Introducing: The Re-Engineered 42mm Hublot Big Bang Meca-10 In Three Versions

Ever since the Big Bang Meca-10 came out in 2016, the watch has stood out thanks to its 10-day caliber with a Meccano-inspired architecture. This year, though the 10-day power reserve isn’t new, some other things are. The re-engineered Hublot Big Bang Meca-10 now measures 42mm in diameter and comes in three variations.

Hands On: Grand Seiko Spring Drive Chronograph SBGC275

Twenty-twenty four marks the 20th anniversary of Grand Seiko’s 9R Spring Drive movement platform, an occasion the brand has chosen to mark with a range of anniversary editions including the Grand Seiko Caliber 9R 20th Anniversary SBGC275. A large, richly detailed watch with a captivating dial, the SBGC275 is robust, interesting, and capable of nearly anything, short of fitting under a short cuff. Initial thoughts At first glance, the SBGC275 looks like just a Spring Drive chronograph with a red dial. But a closer look reveals a highly nuanced colour that changes from red to orange depending on the angle – the result of a proprietary dial coating technique. At 44.5 mm in diameter and nearly 17 mm thick, the SBGC275 is unapologetically big and bold. That said, the watch feels smaller than it is thanks to the use of titanium for the case and bracelet, and the unusually wide 23 mm lug width helps reduce the visual size. This latter dimension may limit the options for aftermarket straps, but since most owners will likely stick with the bracelet, this concern is largely academic. The watch is powered by an upgraded version of the familiar cal. 9R86 Spring Drive chronograph GMT movement, which made its debut in 2007. But eagle-eyed movement geeks will notice the SBGC275 is equipped with the fine-tuned cal. 9R96 first seen in 2017, which was also used in the Nissan GT-R 50th Anniversary edition. In many ways, the SBGC275 captures Grand Seiko’s strengths and weaknesses. The b...

The Difference Between Quartz, Manual, and Automatic Movements Worn & Wound

The Difference Between Quartz, Manual, and Automatic Movements

When shopping for a new watch, the movement is often a point of consideration for many enthusiasts. But what does it do? Simply put, the movement, often referred to as a “caliber,” is the engine powering the watch and regulating the rotation of its hands. While some may feature additional features called complications, their primary duty is accurate time-telling. Today, we’ll walk through the basic differences between manual, automatic, and quartz movements. When shopping for a new watch, the movement is often a point of consideration for many enthusiasts.

Grand Seiko Just Released a Collector’s Dream Watch! Worn & Wound
Grand Seiko Just Released Sep 2, 2024

Grand Seiko Just Released a Collector’s Dream Watch!

At Watches & Wonders 2024, Grand Seiko announced the new 9SA4 caliber and the first two watches featuring it, the SLGW002 and SLGW003. As a refresher, the 9SA4 is a manual hi-beat (36,000 bph), 80-hour, time-only caliber featuring their in-house dual-impulse escapement, first seen in the 9SA5. With a power reserve on the back of the movement, beautiful bridge designs and finishing, and a unique “wagtail-bird-shaped” winding click, it set a new bar for Grand Seiko’s mechanical calibers. But, perhaps just as exciting as the movement itself was that the watches featuring it were sized at an idyllic 38.6mm diameter and 9.95mm thickness with a 20mm lug, addressing the naysayer’s concerns around Grand Seiko’s sizing. While a pair of fantastic releases, since introduction, we have been wondering where we will see this movement next. Well, we just got our answer, and I have to tell you, I’m equally surprised and delighted. They went vintage rather than with the new case and a different dial, which would have been most expected. Yes, they decided to bring back, as a limited edition, of course, a “recreation” of the 45GS from 1968. A little history, the 45GS came out a year after the 44GS and featured the same case design, but differed in that it featured the brand’s first hi-beat manual wound movement, the 4520. The SLGW005 – the return of the 45GS The 44/45GS case defines the Grand Seiko “Grammar of Design” as set out by Taro Tanaka, with flat, Zaratsu poli...

Breitling Debuts First In-House Perpetual Calendar Chronograph SJX Watches

Breitling Debuts First In-House Perpetual Calendar Chronograph

Breitling marks its 140th anniversary with a new calibre, the B19. Based on its longstanding B01, the B19 adds a perpetual calendar on top to create the most complicated in-house calibre in the brand’s stable. The B19 is making its debut in three different models, all clad in 140th anniversary livery: the Premier B19 Datora 42, Navitimer B19 Chronograph 43 Perpetual Calendar, and Super Chronomat B19 44 Perpetual Calendar. Initial thoughts One of the most sophisticated chronograph constructions in the mid range of the price spectrum, the B01 gains a worthy upgrade with the perpetual calendar. Granted the additional complication adds substantial height to the case – all of the three models are well over 15 mm high – but that’s acceptable for a self-winding chronograph with perpetual calendar. Interestingly, the B01 base movement of the B19 has been upgraded over the standard version with some improvements (no doubt courtesy of Kenissi, which bought the rights to the B01 construction), though it’s uncertain if these will make their way into the plain B01. Though all three are identical mechanically, they look and feel different. The Super Chronomat is super chunky and the largest of the three, while the Navitimer and Datora are slightly more compact and definitely more retro in terms of style. The old-school, four-register calendar layout arguably suits the vintage-inspired style better. All three retail for US$59,000, which is par for the course for this double com...

Breitling Teams Up with NBA Superstar Giannis Antetokounmpo SJX Watches
Breitling Teams Up Jul 19, 2024

Breitling Teams Up with NBA Superstar Giannis Antetokounmpo

Breitling’s latest collaboration is a pair of limited-edition Chronomats conceived together with Giannis Antetokounmpo, the Greek-Nigerian basketballer who plays for the NBA’s Milwaukee Bucks. The entry-level model is the Chronomat Automatic GMT 40 Giannis Antetokounmpo in stainless steel, an edition of 1,750 pieces. And then there’s the Chronomat B01 42 Giannis Antetokounmpo in 18k red gold that’s limited to 250. Both share the same dial with baton indices, finished in a green reminiscent of the Milwaukee Bucks’ team colours. And NBA superstar himself gets a unique creation: an all-red gold Chronomat B01 42 with the same green dial but with the registers and flange in contrasting white, along with Eastern-Arabic numerals (pictured above). Initial thoughts The Giannis Antetokounmpo editions are essentially identical to the respective standard Chronomat models, save for the dial colour that’s  a brighter shade of green, along with the basketballer’s discreet “GA” as the second hands counterweight. The chronograph has the addition of a basketball emblem on the seconds register. The basketball elements in the design are minimal, so the two are a good cosmetic alternative to the standard models, even for someone who doesn’t follow basketball since the sport. That’s especially so since the Giannis Antetokounmpo editions are priced the same as the standard models: the GMT costs US$6,150, while the B01 chronograph is US$42,500 on the red gold Rouleaux brac...

Girard-Perregaux Introduces a New Casquette in Collaboration with Saint Laurent

We love quartz watches at Worn & Wound. For many of us, they were the first watches we ever wore, and represent a foundation of enthusiasm that has stretched on for years. There are many, many facets to quartz, and if you think of quartz watches simply as “affordable” alternatives to mechanical, you’re missing out on a lot of history, unique design, and special movements that simply aren’t possible with a mechanical caliber. One of my favorite little quartz rabbit holes is the output of traditional, high-end Swiss brands during the earliest days of the technology, leading up into the period often referred to as the “quartz crisis.” It’s fascinating to look back and see how these brands handled such a major shock to a centuries old industry, and the quartz watches produced by the most storied Swiss brands during this period are almost always significant, carrying with them design attributes that effectively distinguish them from traditional mechanical watches.  The Girard-Perregaux Casquette is one of my favorite examples of a storied Swiss brand experimenting with quartz at the very beginning. The Casquette first appeared in 1976 and was brought back as the Casquete 2.0 in 2022 in a limited edition that quickly sold out to some degree of fanfare and acclaim. The watch has what is now frequently referred to as a “driver’s style” orientation, with an LED display that displays the time digitally when viewed from the side. In the mid-1970s, this certainly ...

Grand Seiko Birch Bark” SLGW002 May 27, 2024

Hands On: Grand Seiko “Birch Bark” SLGW002 and SLGW003

Nature-inspired textures are a consistent motif across Grand Seiko’s portfolio, so it comes as little surprise that the brand would choose this familiar theme for the launch of its newest dress watches, the hand-wind and mechanical Evolution 9 “Birch Bark” SLGW002 and SLGW003.  With a dial that features a fresh take on the texture of tree bark, the Birch Bark is also noteworthy for the movement within: the first manually-wound caliber in Grand Seiko’s 9S movement family that hitherto was entirely self-winding. The SLGW002 (left) and SLGW003 Initial thoughts There are few things I like more than a manually wound, chronometer-grade dress watch. With this bias in mind, I am predisposed to like watches like the Birch Bark. But Grand Seiko made things easy by making it attractive as well, with a new iteration of its Evolution 9 design language that is lighter in terms of visual weight. The big news is, of course, the thickness, or rather the lack thereof. The Birch Bark is 1.75 mm (15%) thinner than its automatic siblings like the SLGH003, answering’ calls for slimmer, dressier options in the Grand Seiko catalogue. The watch is also 1.4 mm (3.5%) smaller in diameter, resulting in a form factor that sits comfortably on the average wrist and will slide under most shirt cuffs. Dimensions aside, the Birch Bark in titanium feels smaller and lighter than expected due to the case material. This runs counter to expectations, since most dress watches are in precious metal....

Oris Aquis Buyer's Guide Teddy Baldassarre

Oris Aquis Buyer's Guide

The Oris Aquis collection of sporty dive watches is one of the Swiss brand’s most popular - and notably hosted the first Oris watch outfitted with the in-house Caliber 400 - even though it traces its history back just over a decade, to 2011. Like many watch models that catch on strongly with both collectors and casual fans, however, it actually represents the successful evolution of several models that preceded it. Here’s everything you need to know about the Oris Aquis, from its history, to the most prominent models available now, to its central role in Oris’ environmental sustainability initiatives.  ORIS ORIGINS AND AQUIS EVOLUTION Oris, one of the watch world’s few remaining major independent brands, traces its history back to 1904, when it was founded in Hölstein, in the German-speaking Swiss canton of Basel-Landschaft, by Paul Catlin and Georges Christian. The company, which the co-founders named after a brook near the factory, expanded throughout the early 1900s, at one point becoming the largest employer in Hölstein, with over 300 employees and factories throughout Switzerland. In 1925, Oris began making wrist watches, and in 1928, under the leadership of Christian’s brother-in-law Oscar Herzog, a new era of expansion and innovation began. Oris started making its own escapements in the watershed year of 1938, which also saw the release of the brand’s iconic Big Crown watch with pointer date function. The first automatic Oris watch was launched i...
