VIDEO: Grand Seiko’s Spring Drive technology explained … in 2 minutes

Fundamentally, there’s not a whole lot of variation in watch movements. Sure, the peripheral details might vary, but basically you’re either looking at a purely mechancial movement, with a mainspring and escapement setup that’s remained pretty much unchanged for the last few hundred years, or you’re looking at a battery-powered quartz watch that’s come to … ContinuedThe post VIDEO: Grand Seiko’s Spring Drive technology explained … in 2 minutes appeared first on Time+Tide Watches.

Something old, something new –that’s the theme that runs through much of watchmaking.  Lest we forget, the basic technology of watchmaking consists of a mainspring barrel, gears, a lever escapement, and a temperature compensated balance controlled by a balance spring.  All of those elements –every one –were in place by 1750, boys and girls, when […]

Insight: Screw-Down Showdown SJX Watches
Omega Speedmaster Moonwatch 1h ago

Insight: Screw-Down Showdown

Mechanical movements attract most of the technical interest in watchmaking, but considerable engineering also goes into keeping them dry. For an everyday watch, the waterproof construction of the case and crown is central to its reliability, yet the way these components keep water out is often misunderstood. Screw-down crowns and case backs are widely regarded as the best way to seal a watch. But the choice is not always straightforward. On a hand-wound watch, for example, a screw-down crown must be unscrewed and tightened regularly, adding an extra step to winding and potentially compromising the threads. The Omega Speedmaster Moonwatch, on the other hand, features a conventional crown and is rated to 50 m. Even so, some owners remain wary of exposing it to more than an occasional splash. So the question is, how much protection can a conventional crown provide, and what does a screw-down construction add? To understand the distinction, we take a closer look at the crown, its tube and the gaskets that form the seal. As a disclaimer, this discussion concerns modern watches with seals in good condition; vintage watches and those long overdue for service should be checked for waterproofness prior to contact with water. A common misconception The actual waterproofness of a joint relates to the uniformity of the seal pressure. In this case, “waterproofness” is used broadly as the ability of a mechanical joint to keep water from seeping in under normal functioning conditions...

Review: the Christopher Ward Sealander - the Best Boring Watch Money Can Buy

Christopher Ward introduced the C63 Sealander in 2021 as a go-anywhere, do-anything watch. It was meant to be the brand’s contemporary, bread-and-butter line: a less specialized variation of the C60 Trident diver that had long been its core, while avoiding vintage pastiche. The Sealander was simple, easy to digest, and versatile. It was also, somewhat, a return to Christopher Ward’s original bang-for-your-buck ethos. When the C63 launched with a $695 three-hand automatic, it was a statement about the brand’s values, not just value. The GMT, meanwhile, started at $950 on a strap. Both offered a lot of Swiss-made mechanical watch for the money. the Sealander in 2021 Fast-forward five years, and I don’t know if any watch brand has changed quite as much as Christopher Ward. The Bel Canto arrived in 2022 and totally reframed how the company was perceived. The Twelve followed in 2023 and raised the standard of its core watches. Then came the Twelve X, which put its in-house movements and finishing capability in the spotlight, and finally the Loco, which proved the Bel Canto was not a one-off. Christopher Ward was redefining what value could mean in the context of avant-garde independent watches. As such, the brand that launched the C63 in 2021 is very different from the one releasing its replacement in 2026. It is bigger, has a much larger customer base, enjoys far greater awareness, and, frankly, has a better reputation. The new Sealander reflects that transformation, r...

The Foundation Haute Horlogerie Expands the FHH Academy by Partnering with the Gemological Institute of America

In 2014, the Foundation Haute Horlogerie (FHH) introduced the FHH Academy, a series of courses that span the fundamentals of watchmaking to culture and heritage as well as more advanced technical curriculums, catering to both industry professionals and enthusiasts. One of the most unique aspects of the program is that it’s offered entirely online in 11 different languages, resulting in participants across 20 countries worldwide. While accessibility has been at the FHH Academy’s core, there are also select courses offered in-person at the FHH headquarters in Geneva as an extension of the platform. Now, the academy is expanding once again as the FHH announces a new partnership with the Gemological Institute of America (GIA). The GIA is globally acknowledged as the foremost authority in gemology and a leader in the gem and jewelry sector. Since its founding in 1931, the organization has set the standard, educating more than 200,000 professionals worldwide across its seven campuses throughout the United States, Europe, and Asia. With its longstanding commitment to education and the dissemination of specialist knowledge within the luxury jewelry industry along with its global reputation and reach, the GIA presented itself as an incredible partner to expand its offerings into the world of horology and for the FHH to expand its in-person training. The partnership marks the first time the GIA has worked with an external entity and allowed trainers outside the institute to teac...

Hands-On: The Pattern Recognition B-Theory Series 1

About a year ago—or maybe two—I remember sitting in an Uber with Ben and some of the Hodinkee team as we drove down the Rue de Lausanne in Geneva, heading to Watches & Wonders. We had just grabbed a quick breakfast when Michael Friedman unexpectedly joined us. Yes, that Michael Friedman. The "AP, Michael Friedman, my friend's cooler" rap lyric guy. The guy who just so happened to have also formerly been a curator at the Willard House & Clock Museum and the National Watch & Clock Museum, Head of Watches at Christie's New York, a client advisor to people like Eric Clapton (during his pièce unique Patek years), and most recently the Head of Complications at Audemars Piguet. Okay, maybe you don't know Michael Friedman. But I knew him well and had some formative early-career experiences bumping into and getting to know him. I also knew he was working on a new brand, but had absolutely zero idea what it was. "It's wild," said Ben—or some approximation of that. "It's not so much a watch as a cuff, with a bunch of diamonds." What could that even mean? I had ideas in my head, but as they spiraled, they got further from the truth. As of a few months ago, we have the answer, and it's not what I had envisioned. The B-Theory Series 1 from Friedman's new brand Pattern Recognition is, as Ben said, far from a watch in most respects, but closer than I expected. Yes, it's jewelry. There are diamonds. And yet it's got the bona fides of technical watchmaking and connections with the pa...

Oris Extends Its Muppets Line with the Most Audacious Version Yet

Like many generations of kids past and present, I grew up on the Muppets, and well, quite frankly, I’ve never outgrown them. They are one of those rare and fantastic so-called kids’ universes that really transcend age and time. However, when Oris first partnered with the franchise in 2023, I was skeptical. Cartoons, superheroes, Muppets – there are plenty I love, and, of course, I also love watches. I’m just not sure I love the two together. Now, I’m fairly certain I’m in the minority. The Oris ProPilot X Kermit Edition seems to be an enduring fan favorite, later followed up by the ProPilot X “Miss Piggy.” The designs are by all accounts very simple and subtle, with Kermit’s face casually appearing in the date window and Miss Piggy only featured on the caseback. Still, something about them always felt a bit kitschy to me. About a month ago, a teaser came through my inbox announcing a forthcoming Muppet model, and I slotted the information away. Like many of us can tend to do once we’ve been deeply ingrained enough in the watch world, I filed the announcement under the category, “this is not for me.” Let this serve as a good reminder to remain open and willing to change your preferences – to be surprised. When I finally got the full press release for the new ProPilot X Gonzo Edition, I started rethinking my position on these types of collaborations altogether. The creativity and attention to detail really blew me away. A lot of brands talk about ma...

Introducing: Gallet Multichron Pilot Hodinkee

Introducing: Gallet Multichron Pilot

What We Know Today, amongst a slate of other launches and re-releases, Gallet — now a part of the Breitling "House of Brands" — lifted the curtain on the Gallet Multichron Pilot. The new watch takes the recipe of the original 1969 Multichron Pilot and updates it, and the result is a watch that is recognizable but also, arguably, the most contemporary model in the very fresh Gallet lineup. The new watch does borrow heavily from its namesake, and seeing the two watches next to each other highlights the similarities. The new Multichron Pilot is still a tri-compax chronograph, with a bi-directional twelve-hour bezel, pump pushers, stick hands, and cut-off arrow-shaped markers. By way of comparison, a vintage Gallet Multichron Pilot. Image, courtesy Analog Shift. But there are definite differences too, many of which are concessions to modern taste. For one thing, those cut-off arrow-shaped indices are now lumed instead of polished, but there's also a date — visible through an aperture at 6 o'clock — and while the telemeter remains on the new watch, the tachymeter (which appeared as a second scale on vintage examples) is omitted. The watch is also bigger than vintage Multichrons.  The new watch has been upsized from 38 to 42mm, is 11.3mm thick, and measures 45.59mm lug-to-lug. At that size, the new Multichron Pilot is the largest watch in the new Gallet catalog but is still quite reasonable and a far cry from some of the oversized watches that still seem to populate Bre...

Zenith Chronomaster Solo Sport What Sep 2, 2026

Introducing: Zenith Chronomaster Solo Sport

What We Know Now in its sixth decade as one of the most famous movements in the industry, the El Primero remains at the heart of Zenith's offerings. To kick off Geneva Watch Days, Zenith is doing something slightly different, launching a Chronomaster Sport without a chronograph—the Chronomaster Solo Sport. The watch arrives in four variations: three with ceramic dials and bezels in black, white, and brown, plus a no-date option also in black. All four come in a 40mm stainless steel case with a ceramic unidirectional rotating bezel. The dial features hours, minutes, and seconds, with date added on three of the four references. Despite losing the chronograph, there's still a lot going on up top. The words "36,000 VpH" and "high frequency" alone take up two lines of the dial, and the subtle "shark tooth" minute track gives a nod to vintage Zenith references.  The dial itself is ceramic, built around a repeated 45° Z motif meant to evoke the rhythm and vibration of the movement underneath—rendered as a sunray finish on the white version and a polished surface on the black and brown versions. That same pattern carries over to the counterweight on the seconds hand. The El Primero 3620 powers the watch, derived from the El Primero 3600 chronograph movement and operating at 5 Hz, or 36,000 VpH, while retaining the star-shaped rotor. It's equipped with a silicon escapement and a stop-second mechanism for precise time-setting, and it offers a 60-hour power reserve. Also featur...

Introducing: TAG Heuer Monza Flyback Chronograph Carbon Limited Edition Hodinkee
TAG Heuer Monza Flyback Chronograph Carbon Sep 1, 2026

Introducing: TAG Heuer Monza Flyback Chronograph Carbon Limited Edition

What We Know This weekend, Formula 1 returns to Ferrari's home track (for the series, at least) of Monza, and with that return, TAG Heuer is releasing a new version of the eponymous Monza Flyback Chronograph. The watch was originally released in 1976 to celebrate Ferrari's return to the top with the constructors' and drivers' Formula 1 championships, with its black-coated case setting the stage not only for the model's future but also for similar releases from Heuer (and later TAG Heuer). A Monza isn't a Monza unless it's black, so this new release fits the remit perfectly: a 42mm by 15.22mm case in forged carbon, with red accents on the dial. Often known as the Niki Lauda (after the driver who won the title in 1976), the original watch featured a lot of red (and was reissued over a decade ago), though the dial layout has changed significantly from the original. This time, that red has been swapped around, with accents on the minute-counting and chronograph hands, the combination pulsometer and tachymeter flange scale, and the flyback mark at 6 o'clock. The date is still included, moved to 9 o'clock (which in turn puts running seconds at 6 o'clock), but with an angled window. The indices are all printed, and the hands and hour markers use white Super-LumiNova. The watch is powered by the COSC-certified Caliber TH20-12 automatic movement, running at 4Hz. TAG Heuer didn't provide specifications here, but past versions of the Monza with this movement had an 80-hour power rese...

These are 9 Under the Radar Enamel Dials You Should Know

Probably one of the proudest informal titles I’ve garnered in my nearly 15-year career in the watch industry is “the resident enamel girl.” As a refresher, I fell in love with the artform in a hands-on workshop during a press trip several years ago and have gone on to complete three different apprenticeships in Switzerland studying the craft. I have an immense appreciation not only for the beauty of enamel dials but also the meticulous creative process behind them. Enamel dials were long held in esteem as one of the elements of watchmaking reserved for the elite, much like high complications. It’s no small feat to bring a well-executed enamel dial to life. The materials, tools, machines, and the expert level of training for the craftspeople were once gripped tightly by top brands like Patek Philippe, Breguet, Vacheron Constantin, Jaquet Droz, and Van Cleef & Arpels. Let me be clear – in practice, brand clout ultimately does not correlate to the best enamel dials. There’s a particular maison not named here (and who I will not call out by name) but who is one of the biggest names in the industry, with every resource at their disposal, and one of their recent and highly popular enamel dials is unbearably mediocre if you give it a look under a loupe. Thankfully, the collector community is starting to come around to this notion that enamel from independent brands can be equally good if not better than the old guard. If you need further proof, here are nine under the...

Wren Introduces the Diver One Abyss Worn & Wound

Wren Introduces the Diver One Abyss

Are you afraid of the dark? No, really—it’s one of the most common phobias and for good reason. The dark represents the unknown, the impossible, and the very idea of danger. And while that uncertainty often leads to an understandable (and innately biological) fear reaction, it also makes the dark exciting beyond measure. Why else would we send divers down to the crushingly dark abyss of the deep ocean? New York City-based microbrand Wren has taken that question head on, and turned it into a dive piece that embodies the environment it’s inspired by: The Wren Diver One Abyss. The single most striking thing about the Abyss is, of course, its namesake. The dial is black, with a black bezel, but it’s not a “normal” black; instead, Wren has made use of the Koyo Orient Japan-derived Musou Black water-based acrylic paint that absorbs 99.4% of visible light. Unlike other such “superblack” paints, like the infamous Vantablack, Musou Black is commercially available, and while it’s not quite as dark as the former, it bears a lot of similarities in composition. Koyo keeps the full breakdown close to their proverbial chest, but basically, what makes it “darker than dark” is its ability to bounce light back out, giving the human eye nothing to latch onto. This makes the color read as bottomless, giving it a strange, disconcerting “depth”, which Wren furthers by using a sandwich construction method for the markings and indexes (additionally coated with Super-Lumi...

Longines Adds a Light Blue Conquest Heritage Central Power Reserve

Don’t look now, but Longines is having an uncommonly strong year. The release of the reworked HydroConquest dive watch in March remains one of the most discussed new releases of the year from a major brand, and their quiet but smart update of the Master Collection in June was also well received. Last month, they launched a new version of one of the more curious watches to be plucked from their archives in recent years, and while it’s certainly more of a niche product than the diver or the classically styled pieces in the Master Collection, it shows that the brand is still considering the enthusiast in spite of what is clearly a larger, big tent approach focusing on core models.  The Longines Conquest Central Power Reserve in light blue is the third such watch following cream, anthracite and black dials introduced in 2024. These are incredibly charming watches in person, and lift from a design that originally debuted in 1959. It’s a fairly straightforward watch, with the central quirk (literally) being a power reserve indicator represented by a subdial in the dead center of the dial. The date appears at 12:00, and studying the dial reveals an idiosyncratic sector-like layout that is easily readable and visually interesting.  The case of the Longines Conquest Central Power Reserve measures a tidy 38mm in diameter and 12.3mm thick. That is a tad taller than I’d typically like on a watch in this style, but I think it’s the price we pay for a modern, tech forward mo...
