Grand Seiko After Dark, “Moonlit Birch” SLGW007 SJX Watches
Grand Seiko After Dark “Moonlit Birch” Sep 22, 2025

Grand Seiko After Dark, “Moonlit Birch” SLGW007

Grand Seiko has been fairly quiet over the summer, but has just unveiled the latest addition to its Evolution 9 collection, the “Moonlit Birch” SLGW007. Effectively a new variant of the “Birch Bark” SLGW003 with a steel case and navy blue dial, the Moonlit Birch is a competent alternative to its titanium stablemate. In other words, it’s an attractive new livery for what was already a compelling watch, and retains its best characteristics including a nuanced and ergonomic case, gorgeous dial furniture, and the brand’s latest manually wound cal. 9SA4 movement. Initial thoughts The original “Birch Bark” launched last year and was one of the standout releases at Watches & Wonders due to its elegant case profile and impressive new movement. The Moonlit Birch is identical in most respects, but the case is stainless steel, rather than titanium, and the dial is finished in navy blue instead of bright white. Despite these modest differences, the Moonlit Birch is appealing in its own right. The dial texture is subtle, but it’s enough of a Grand Seiko calling card to prevent the watch from looking too generic; a common trap for time-only dress watches. The stainless steel case exhibits the brand’s Evolution 9 styling, which gives the Moonlit Birch a bold, angular presence. In answer to the demand for slimmer options from Grand Seiko, the dimensions are nearly ideal, 38.6 mm in diameter and just under 10 mm thick. The watch is powered by the cal. 9SA4, which is pa...

Is The Classic Fusion Black Magic Hublot’s Dark Horse? (Hands-On)

Hublot are an ever-present disruptor of the traditional watch industry, but do the brand’s horological standards ‘walk the talk?’ Let’s find out! What We Love: Tough, light & unobtrusive on-wrist Bold design married with demure aesthetics Surprising variation of finishes and detailing What We Don’t: No lume on a sports watch? Chronograph operation feels tougher than most Movement choice makes for a challenging value proposition Overall Rating: 8/10 Value for Money: 7/10 Wearability: 9/10 Design: 8/10 Build Quality: 8/10 When I was first introduced to the luxury watch industry and all the wonders it holds, it was an overwhelming experience. This isn’t a ground-breaking revelation – I’m sure many of you shared the same circumstances at one point – but I found myself quickly scrambling for some watch advice, no pun intended. However, since I was the only watch nerd (that I knew of) in my demographic, I naturally navigated online. There, I was told a great many facts and rules. Some of them were good, like “don’t change the date between 9 and 3 o’clock,” or “take the watch off before you adjust the time.” Other bits and pieces, however, were just opinions disguised as fact. “Never buy [this brand],” “only buy [that brand] …” All the typical drivel we roll our eyes at now; I integrated into my own beliefs as a then watch noob. Of course, this also led me to one of the watch community’s biggest discourses: Hublot. From what I saw, th...

Zenith’s DEFY Skyline Chronograph Review: A Beautiful Blue Ceramic Masterpiece

This isn’t just another colour variant, it’s Zenith pushing the DEFY Skyline Chronograph into full-ceramic territory with its signature blue. The result is a watch that turns heads like a show car but wears like a daily driver. A fitting 160th-anniversary statement piece that blends Zenith’s history with its future. What We Love Full royal-blue ceramic case and bracelet give the watch a bold, cohesive look that stands out from almost anything else in this price segment. Despite the 42 mm size, the ceramic construction keeps the watch surprisingly light and wearable, even on slimmer wrists. Zenith’s El Primero 3600 combines high-frequency accuracy, 1/10th-second timing, and a 60-hour reserve. What We Don’t Matching blue sub-dials keeps the design cohesive, but doesn’t have visual separation compared to contrasting colours. The date at 4:30 is a necessary compromise but still slightly disrupts dial symmetry. Ceramic links can be trickier to size and adjust compared to steel bracelets. Overall Rating: 9/10 Value for money: 9/10 Wearability: 9/10 Design: 9/10 Build quality: 9/10 Earlier this year, Zenith released a host of blue ceramic timepieces in celebration of its 160th anniversary. The timepieces included the Pilot Big Date Flyback, Chronomaster Sport, DEFY Skyline Chronograph, and, of course, the very special Zenith G.F.J timepiece. These special limited edition models were given the blue colour treatment as it’s a signature colour of the brand. The colour ...

Rolex Daytona Rainbow: When An Icon Goes Colorfully Gem-Set

Aside from the watch that was made legendary by Paul Newman - and which would forever, unofficially, carry the famous actor’s name - there is probably no version of the Rolex Daytona that is more coveted than the “Rainbow” models that bring a meticulously designed and eye-catchingly beautiful assortment of colorful precious stones to the bezel, case, and dial of the motorsport-inspired luxury chronograph. Here is the story behind the Rolex Daytona “Rainbow” and why it has become yet another smash hit for the Crown in the 21st Century.  To start off, it’s worth answering the question, “Why is the Rolex Daytona so famous in the first place?” The model’s success story begins in 1962, when Rolex, hot on the heels of other genre-defining watch releases like the Explorer, GMT-Master, and Submariner several years earlier, became the official timekeeper of the “Great American Race,” the Daytona 500. In celebration of the partnership, the Swiss brand introduced its original “Cosmograph” racing-inspired chronograph watch the following year. The watch, notable for its tachymeter bezel and three-register dial design, adopted the name “Daytona” shortly thereafter and really took the enthusiast community by storm when actor, director, and part-time racecar driver Paul Newman began wearing one regularly. Newman became a big-screen icon in the 1970s, around the same time that auto racing took off in popularity as a spectator sport, and this confluence of...

Our Favorite Seiko Watches of All Time Worn & Wound

Our Favorite Seiko Watches of All Time

When it comes right down to it, there’s no more important watch brand to the enthusiast community than Seiko. Sure, Rolex is the biggest brand in the world, and the most recognizable brand name (for any product) ever. But no other brand matches Seiko for variety, accessibility, quality, and pure fun. There’s truly something for everybody under the Seiko tent, and it’s a brand that we find ourselves unable to quit, even when they frustrate us for any number of reasons.  But this isn’t about those frustrations. This post is about the Seikos we love the most. We asked our contributors to pick their favorite Seiko of all time, and we think as you read through these selections you’ll find that the thing that ties them all together is a deep personal connection to a watch. That’s what’s at the heart of this hobby, and what makes Seiko so special.  We want to know the Seikos that you love the most, so let us know in the comments what you’d pick.  Elodie Townsend – Seiko Flightmaster SNA411P1 I can’t hear the name Seiko without getting misty-eyed about the watch that introduced me to the wider world of horology fandom: the Seiko Flightmaster SNA411P1. It’s big, brazenly busy, and admittedly over-packed with features that I would never use (calculus, anyone), but that pop of yellow and the charm of its over-complications make it a joy to wear, use, and show off.  My dad got me my “Flighty” as a gift for my 21st birthday years back; when the price hadn...

Fortis Introduces the Stratoliner S-41 Reentry Edition, with a Heat Treated Titanium Dial Worn & Wound

Fortis Introduces the Stratoliner S-41 Reentry Edition, with a Heat Treated Titanium Dial

Space, fire, time. These things are elemental, conduits to deep discussions about our place in the universe, and the nature of life itself. What does it all mean? It’s the stuff of 3:00 AM dorm room deep dives, the kinds of conversations that happen after watching 2001 for the first time. Every so often, a piece of art, or an object (or even a watch!) scratches at these ideas. That’s what I started to ponder, anyway, when I first read about the new Fortis Stratoliner S-41 Reentry Edition, a striking new version of their spacefaring chronograph with a unique (literally) dial with one of the more interesting concepts behind it that I’ve seen this year.  The highlight here, as you can likely derive from the images, is the dial that has been heat treated by hand. The inspiration comes from spacecraft reentering the earth’s atmosphere. This happens at an incredibly high rate of speed – roughly 15,000 miles per hour. At that velocity, the friction caused by the spacecraft as it comes in contact with the atmosphere essentially turns said spacecraft into a small, fast moving, fireball. Have you seen Apollo 13? Then you know basically how this works. A heat shield designed to control that burn keeps astronauts on board safe, and the critical structure of the spacecraft intact.  According to Fortis, every Reentry Edition dial is heat treated by hand and completely unique, thanks to the unpredictable nature of the impact of fire on the titanium surface. The heat produces ...

Grand Seiko Goes Gold SJX Watches
Grand Seiko Goes Gold Grand Seiko Sep 19, 2025

Grand Seiko Goes Gold

Grand Seiko has unveils three gold Spring Drive models with the new 9RA2 movement, the Japan-only Heritage Collection SLGA030, SLGA027 and SLGA028, in rose, white, and yellow gold respectively. The new collection benefits from a slimmer case, a longer power reserve, and some new dials to go with the satisfying heft of a full 18k gold bracelet that weighs in at almost 200 g. SLGA030 in rose gold. Initial Thoughts While mostly unknown outside Japan, a trio of gold Spring Drive models in 44GS-style cases on full gold bracelets were a staple of the domestic Grand Seiko catalog for nearly a decade, powered by the cal. 9R15 that was once the brand’s finest automatic Spring Drive movement. While identical to the cal. 9R65, save for a gold medallion on the rotor, Seiko set aside the best performing quartz timing packages for these special movements. The earlier generation of all-gold models, from left to right: SBGA364, SBGA361, and SBGA362. Grand Seiko has decided that now is the time to refresh the line with the upgraded cal. 9RA2, while preserving the heavyweight gravitas and luxurious bracelet of its predecessor. I have anticipated these watches since the second generation of Spring Drive movements launched in 2020; it took five years, but the result meets my expectations, though I would have liked a gold winding weight to match the case material. Selling watches on full precious metal bracelets in this segment is a mark of a strong brand. Gold prices and luxury margins bein...

What is a Rehaut on a Watch Dial? Teddy Baldassarre
Sep 18, 2025

What is a Rehaut on a Watch Dial?

Most parts of a watch that you’ll encounter in your pursuit of horological knowledge are names that are fairly familiar and mostly self-explanatory: case, dial, hands, movement. (We run down the gamut of the most important watch parts in this article). But now and then, you may read about, or hear someone referring to, a watch’s rehaut - a somewhat intimidating-sounding French term that might give you pause at first. What is a rehaut, and what is it used for? Read on. Put simply, a rehaut (properly pronounced “Re-OHH” without the hard “T” sound at the end) is the French word for “flange,” which is the English term most often used in its place when discussing watches. It describes the rim between the periphery of the dial and the crystal. Unlike dials and cases and hands, not every watch has one. But for many of those that do, the rehaut is not only a frame that fills in the space between the dial edge and the crystal but also a utilitarian element that can add interest and even useful information to the dial itself.  Some watchmakers use the rehaut for staging the hour or minute markers, In the case of chronographs, like the TAG Heuer Carrera featured above, the rehaut can provide a spot for added functional markings like a tachymeter scale (which can use the built-in stopwatch to measure speeds relative to distance) or a pulsimeter (which works with the chronograph to measure heartbeat rates). Other watches might use the rehaut for calendar indications ...

Tissot Unearths the RockWatch SJX Watches
Tissot Unearths Sep 18, 2025

Tissot Unearths the RockWatch

Tissot reissues the iconic RockWatch of 1985, now in a larger case but once again made of granite sourced from the Swiss Alps. Although Tissot took a few liberties to suit modern tastes, such upsizing the case to 38 mm and adding monochromatic hands, the new RockWatch is impressive for its fidelity to the original, and retains all of the important details including its one-piece case and dial. Limited to 999 pieces, the RockWatch extends Tissot’s run of mining gems from its back catalogue. Initial thoughts Tissot has been digging through its archives for over a decade now. After excavating the enormously successful PRX in 2021, the colourful Sideral in 2023, and long-dormant Stylist last year, Tissot has finally hit bedrock. Watch cases carved from stone predate even the balance spring, but remained extremely niche and were often quite expensive until Tissot’s original 1985 RockWatch. While originally launched in Alpine marble, the line expanded to include numerous other materials. Historical RockWatches were produced in a variety of materials and featured red and yellow hands inspired by Alpine trail markers. As with most modern reissues, the 38 mm RockWatch is significantly larger than the originals, which were offered in 23 mm, 30 mm, and 33 mm sizes. In addition, modern AR-coated sapphire stands in for the tempered glass crystal of the original. Though larger, the construction is consistent with that of the original with its monobloc case and dial, which are milled...
