What is a Quartz Watch? Everything You Need to Know Teddy Baldassarre

What is a Quartz Watch? Everything You Need to Know

The advent of the quartz watch was the most disastrous event ever to befall the traditional luxury watch business, an existential threat that nearly toppled the watch industry as we know it. The invention of the quartz watch was among the most significant advances in the history of timekeeping and brought affordable wristwatches to the masses in a way that had never been seen before. These are the two main schools of thoughts on what the quartz watch has meant to the history of watchmaking, and both are essentially correct. As you contemplate whether to purchase a quartz watch, ponder the main differences between quartz and mechanical movements, and try to wrap your head around the various types of timekeeping technologies, let’s explore how quartz watches originated, how they evolved, and what their place is in today’s ever-changing watch world.  [toc-section heading="Quartz Movements Explained"] Unlike a mechanical movement, which stores its energy in a wound mainspring inside a barrel and releases it through a complex series of gears to move the hands, a quartz movement derives its power from a small electrical charge provided by a battery, which then passes through an integrated circuit that applies the charge to a tiny quartz crystal cut into the shape of a tuning fork. Thanks to something known as the reverse-piezoelectric effect, that tiny charge applied to the quartz tuning fork crystal causes it to vibrate at an incredibly high rate that dwarfs the output of ...

The Yema Navygraf is the Latest Diver to get the Mother of Pearl Treatment Worn & Wound

The Yema Navygraf is the Latest Diver to get the Mother of Pearl Treatment

There is something about mother-of-pearl that seems to be catching watchmakers’ eyes lately. While I highly doubt it has to do with the fact that “Mother of Pearl” is a phenomenal drag name, I can’t totally rule that out as a possibility. Instead, more likely, it has to do with the ease in which adding the iridescent substance onto an existing design gives it new personality without really reinventing the wheel. Case in point: Yema’s Navygraf Pearl. Undoubtedly, the Navygraf is a handsome watch. But, like a drag queen, sometimes it’s hard to describe something as both “handsome” and “pretty” simultaneously. At least, that was my first impression of this French-made watch. Using the classic dive watch model, like the Navygraf, and inlaying mother-of-pearl seemed, in a way, incongruous to the steely, masculine athleticism of the silhouette. But, upon examining the bezel and dial a little more closely, I’m more inclined to think this is less of a gimmick and more of a thematic appreciation for the beauty and sport that the ocean provides (unfortunately, I’m only speculating – the press release was more focused on the technical specs of this Navygraf). So, what are the specs? This is a thinner Navygraf variant, equipped with a micro-rotor caliber CMM.2, meaning that the 316L stainless steel case measuring 39mm, only clocks in at 9.75mm thickness. The CMM.2 caliber also promises around 70 hours of power reserve, making it suitable for any diving trips ...

Seiko Tank Review: This $210 Dress Watch Is A Hidden Gem

Seiko has no shortage of dress watches, many of which come from the Presage collection, which boasts some of the best values out there. That said, I recently came across a watch that not only comes from the Japanese brand's more basic, entry-level Essentials collection, but is actually the cheapest Seiko out there at the moment. Yes, the Seiko SWR064 is affectionately dubbed the Seiko Tank for obvious reasons, but there is something distinctly Japanese about it. I had my initial doubts about this watch, but when factoring in the design, style, and price, there was no real way of getting around the fact that this is a starter dress watch that exudes value. Let's get into why. Seiko "Tank" Case The case of this Seiko “Tank” is done in stainless steel, with a gold-plated finish that really fits in with the retro styling. I’m usually really turned off by gold-plating but the cohesiveness with the dial elements pulls it together. As for the size, it measures 27.9mm wide, 38.5mm tall, and 6.7mm thick (30 meters of water resistance). For the sake of comparison, the Cartier Tank Louis “Extra Large” comes in at 27.75mm wide, 38.1mm tall, and 8.18mm thick, so the sizes are very close. There’s not a lot of chatter about this watch out there but I did notice some people say it’s too big to be anything like a Tank, which is demonstrably false. The similarities don’t stop there, as the positioning of the brancards is similar - though I do wish they were just a little b...

Vacheron Constantin Overseas Dual Time Review: Is It The Ultimate Luxury Travel Watch?

The Vacheron Constantin Overseas Dual Time is a piece I’ve wanted to review for a while now, and finally, my wish has come true. So, how did it live up to expectations? What We Love The versatility of the piece being a sports watch that dresses up or down Ease of use of the Dual Time function and quick set date The brushed silver dial really stands out with an easy to read layout. What We Don’t The watch can wear on the larger side, especially on the bracelet The bezel is prone to surface marks, like most polished metal bezels The strap thickness at the base tends to flare out a little depending on your wrist shape and size Overall Rating: 8.75 / 10 Value for Money: 8/10 Wearability: 8.5/10 Design: 9/10 Build Quality: 9.5/10 There’s something special about a watch that can seamlessly blend luxury with everyday practicality – and that’s exactly what Vacheron Constantin has achieved with the Overseas Dual Time.

Leica’s Latest Watch Collection is Here: Introducing the ZM 12

Sometimes when a new brand enters the ultra competitive watch market, it’s tough to know how seriously to take them. There are many, many upstart watch brands that come in hot and flame out quickly. We can all point to watches and brands that we’ve liked, seemed like a good idea, and then faded away, never to be heard from again. We can also, I’m sure, point to brands that have surprised us with their durability, and stuck around much longer than many would have initially thought. But that’s part of the game when it comes to independent watchmaking – it’s always a bit of a roll of the dice.  These feelings got, well, complicated when Leica entered the watch market a few short years ago. Leica, of course, is a brand that we take very seriously at Worn & Wound. For some of us, it’s a brand that we truly revere for their contributions to photography and the truly exceptional cameras and lenses they produce. So it was tough to know what to make of their entry into the watch world. I think the fear for many was that their watches would simply be licensed products, Leica literally in name only, and produced by the lowest bidder in a manner that lets down everything else they make.  In retrospect, it was silly to be so concerned. Leica, as a brand, seems to have a keen understanding that their products are associated with manufacturing excellence, and that this is a belief held even by those who have never owned or even handled a Leica camera. Their brand image is...

Hands-on – The new Citizen Mechanical Day/Date NY4058 is a Perfect Example of a Gateway Mechanical Watch

When you read magazines like MONOCHROME, stepping into the (absolutely fascinating) world of mechanical watchmaking can be frightening. Not only can these watches be hard to understand, filled with complications and complex mechanical devices, but the prices at which most luxury watches are offered generate a “glass ceiling” effect that’s hard to break. There is […]

Where aviation heritage meets contemporary design, the Zenith x Porter PILOT Big Date Flyback Chronograph delivers bold style and functionality! What We Love The khaki green colour for the case and dial Orange accents stand out beautifully The case isn’t big, even for slimmer wrists What We Don’t The black crown and chronograph pushers seem out of place with the rest of the watch’s colour scheme. Different font are used throughout the dial Velcro strap won’t suit everyone, especially with slim wrists. Overall Score: 8.6 / 10 Value for Money: 8.5/10 Wearability: 8/10 Design: 9/10 Build Quality: 9/10 The Zenith X Porter Pilot Big Date Flyback Porter stands out as a shining example of thoughtful design and craftsmanship in a world where collaborations feel like the norm.

Serica’s Parade is the Brand’s Most Ambitious Watch to Date

Nearly a year ago I sat in on a conference call with some colleagues and members of the Serica team, who outlined their upcoming slate of 2024 releases. They were particularly excited about a new watch they weren’t yet ready to show us that would debut toward the end of the year, a watch they claimed was a significant departure for them in terms of style, shape, and what enthusiasts have come to expect from Serica over the last five years. While not an anniversary piece, per se, they framed this release as one that celebrates the brand and their unique perspective on the watch world, and now, finally, having seen the new Reference 1174 Parade, their excitement makes a lot of sense. This is an ambitious release, and should go a long way in expanding what the community might expect from Serica going forward.  Serica has built their brand on designing purpose built but elegant tool watches in the style of classics from the midcentury period made by Rolex and countless other historic brands. Their watches tend to have a very clear vintage influence without being too on the nose – they never mimic or borrow completely from any specific classic watch. The same holds true for their first watch in a more formal vernacular. The Parade jumps in the shaped case arms race with a dramatic oval, stepped case in what the brand calls a “Stadium” footprint: straight sides, but with soft, curved corners that suggest both roundness and length simultaneously.  The watch might immedi...

The Exaequo Melting Watch is a Surrealist Take on Watch Design Worn & Wound
Cartier Crash OK maybe it’s Nov 5, 2024

The Exaequo Melting Watch is a Surrealist Take on Watch Design

If you’ve been paying attention to the world of the Hype Watch over the last few years, you’ve no doubt stumbled upon the hypiest Hype Watch of them all: the Cartier Crash. OK, maybe it’s not the hypiest Hype Watch, but it’s close. In terms of genuine rarity and the Crash’s ability to show up on the wrists of movie stars, recording artists, and top tier influencers with regularity, it’s certainly a big part of the conversation. There are a lot of reasons why the Crash has become so sought after in recent years, but one of them is certainly a movement among the larger watch market to pieces that are, at least on the surface, more unusual, and lead with design. The Crash, then, is really part of the rising tide that is lifting the ship of shaped cases more generally. And that brings us to the Exaequo Melting Watch, an unusual avant-garde design with a shaped case that is, at least in some ways, Crash adjacent, but a small fraction of the cost and quite a bit more approachable.  Longtime enthusiasts might remember the Exaequo Softwatch from the 1990s, which has carried on cult favorite status even to this day. The Melting Watch is effectively the modern rendition of the Softwatch, and has been brought back this year in a well timed bid to take advantage of a movement toward uncommon shapes and designs.  While the possibly apocryphal story of the Crash involves a Tank being accidentally melted in a fire after a car wreck, Exaequo has always proudly touted their w...

Grail Watches: The Holy Trinity – Patek Philippe, Audemars Piguet, and Vacheron Constantin – And What is a ‘Grail Watch’ Anyway?

“The Holy Trinity,” as any watch nerd knows, refers to the triumvirate of Patek Philippe, Audemars Piguet, and Vacheron Constantin. Colin Smith takes a look at what we mean – or think we mean - when we describe PP, AP, and VC as the “Holy Trinity” of watchmaking and when we describe a timepiece as our “grail watch.”

Is the Seiko Presage SPB445 the best Arita Porcelain dial watch yet?

One of the things that makes Seiko such an interesting brand is that it’s not afraid to celebrate its Japanese-ness. This is most commonly expressed through the brand’s dials, which frequently pay homage to different elements of Japanese nature or culture.

The Speake Marin Ripples Infinity Date is One of the Best Named Watches and Coolest Under the Rader Integrated Bracelet Sports Watch Options Around

I have a small obsession with watch naming conventions. I’m absolutely fascinated by the decisions brands make in what to call their watches. Some brands, for example, use only reference numbers, and collectors wind up giving the most popular watches nicknames (Grand Seiko comes to mind, although last year saw a notable exception to the rule). Then there are countless brands that incorporate language of adventure, particularly on high seas, into watch names: the Submariner, the Supermarine, the Sea-Rambler, and on, and on, and on, and on. And of course there are brands that steal a strategy from car manufacturers (or is it the other way around?) and give their watches names in one of the Romance Languages, an attempt to instill a sense of class and taste. But what I like are the simple and punchy names that get right to the root of what the watch is about. Memorable, sometimes funny names that communicate an ethos and make you go, “Oh yeah, of course,” all at once. The Speake Marin Ripples is one of my all time favorites.  The Ripples is Speake Marin’s take on the integrated bracelet sports watch, a category that seems about as far afield as you might get from the brand’s roots, but that’s a story for another day. In my opinion, the Ripple is one of the most distinctive integrated bracelet designs to come on the scene in this recent period during which everyone under the sun has tried their hand at this type of watch. It belongs, I think, in the same conversat...

The New Field Chronometer From Serica is Full of Subtle Upgrades to the Watch that Put the Brand on the Map

Just in time for the Windup Watch Fair, Serica has announced their latest release, an update to the original field watch that brought them to the attention of so many collectors just a few short years ago. The new 6190 Field Chronometer gives away a key update in the very name of the watch (bringing it up to spec with the rest of the collection), but there are a host of other refinements that speak to the continued improvements Serica have made with each release. We’ve seen a number of brands putting contemporary spins on the classic field watch recently, and the new release from Serica serves almost as a counterpoint. An example of a more traditional field watch, but seen through a modern lens.  The case of the new 6190 Field Chronometer has been overhauled with slightly more complex geometry and a thinner profile that should please owners. The case height is now just 10.4mm, and Serica has maintained the impressive 200 meter water resistance rating even with the more slender dimensions. The diameter is just under 38mm, and the lug to lug span is 46.5mm, which equates to a watch that should wear much like the vintage watches that inspired it. The flat, brushed bezel is also now slightly wider, and the twisted lugs have a new polished chamfer along their outer edge.  In addition to the case updates, Serica is offering the 6190 Field Chronometer in three new dial variants. The Denali is Serica’s first fully lumed 3-6-9 dial, with hour markers that have been moved inwa...
