The Grand Seiko 45GS Returns with the New Hand-Wound Hi-Beat Caliber 9SA4

Photo Report: Assembling Caliber 9SA4 at the Grand Seiko Boutique

I’ve always had a fascination for peeking behind the curtain. Whether it was tearing apart broken electronics, rebuilding car engines, or opening the caseback of my first Seiko, I’ve always wanted to see and know how things work. As I’ve gone deeper into the horology rabbit hole, I’ve become more interested in the physical process of assembling a movement. While I can watch any number of YouTube videos, there’s something special about seeing it done in person, especially when you get to watch a Grand Seiko Watchmaker at work. Last week, I was invited to Grand Seiko’s boutique for a live assembly of their new 9SA4 movement, a high-beat, manually wound high frequency movement featuring Grand Seiko’s proprietary dual impulse escapement and 80 hours of power reserve. If you’d like to learn more about the 9SA4 and how it was created from the 9SA5, Zach Kazan covers that in detail here. This event was hosted at Grand Seiko’s Madison Avenue boutique (we celebrated the grand opening of this boutique in March, click here for the recap article) which features a gorgeous open concept main level, and an intimate lower level they’ve dubbed “The Cellar”. Unlike any cellar I’ve ever been in, this lower level features multiple lounge spaces, a full bar, a dedicated presentation space and, of course, plenty of watches. You’ll also find various items of cultural significance from the towns surrounding the Grand Seiko Studio Shizukuishi, which inspire the design o...

YEMA Launches a Kickstarter to Support a Manufacture Caliber in New Superman Bronze References

Watch brand YEMA has long been synonymous with French elegance and their latest model, the Superman Bronze CMM.10 is no exception. Utilizing crowd-funding through Kickstarter, YEMA has produced a limited edition watch that is as architectural in design as it is reliable when it comes to performance. Available in two sizes (39 and 41mm) and two dial color options (gradient blue and lacquered black), potential customers have the choice of a watch that best suits their individual preferences. Both dials are a striking contrast to the bronze, adding a balance of warm and cool tones that pair well with the rugged design of the Superman model. The watch itself has undergone a few changes from the original Superman models, most notable in the subtle upgrades to the dial, including the iconic “shovel” second hand has been replaced with a lollipop sweep hand, creating a more harmonious overall design. The timepiece now proudly exhibits French engravings and features the new “MANUFACTURE FRANÇAISE” signature thoughtfully placed at the 6 o’clock position. This change reflects YEMA’s updated brand positioning, resulting from their decision to internalize the manufacturing of components for the CMM.10 caliber. Speaking of the CMM.10 caliber, this movement promises 70-hours of power reserve and is rated to -3/+5 seconds per day is made from non-magnetic alloys to keep it from being impacted by magnetic forces during daily use. YEMA says that they worked in collaboration wit...

Collective Horology Introduces their Latest Limited Edition, a Collaboration with Montblanc Featuring a Gorgeous Minerva Caliber

Collective Horology, the private watch club/independent brand retailer/producer of thoughtful limited editions, is back with their latest release in an ongoing series of collaborations. This time, they’re working with Montblanc, tapping into the brand’s association with the historic Minerva manufacture, maker of some of the most important chronograph calibers in the history of watchmaking. The 1858 Minerva Monopusher Chronograph “Blue Arrow” P.05 is a high end “What if…?” hypothetical come to life, and a great showcase for a truly special movement. As with all Collective limited editions, this one is something more than a reissue or a tweaked colorway. It exists to tell a specific story about the brand in a way that can often only be done from the outside.  According to Collective, the seed of inspiration for the P.05 came from Eric Wind, or more specifically a watch in his case at the 2022 Windup Watch Fair. That year, Eric brought a Minerva stopwatch to the show, and it reminded Collective founders Gabe Reilly and Asher Rapkin of Minerva’s sporting roots, opening up a series of entirely new design possibilities. The 1858 Monopusher Chronograph that Collective and Montblanc came up with drew on the sportier design cues from that stopwatch, including the colors, finishing techniques, and the case material (robust stainless steel, of course). The end result is a chronograph that has many key vintage inspired design elements that are core to Montblanc and Mi...

Lorier Updates their Hydra and Hyperion Lines with New Watches Featuring the Miyota 9075 “Flyer” GMT Caliber

A few years ago, one of the most discussed topics on watch forums, Instagram, and indeed in the Worn & Wound office, was the huge opportunity and desire among enthusiasts for a new crop of affordable GMTs with local jumping hour capability. For a time, it seemed that small watch brands could not keep up with demand for so-called “caller” GMTs with independently set 24 hour hands, but these watches are in fact massively inconvenient for travel, even though, in most cases, they were marketed and sold as watches tailor made for crossing time zones. A watch with an hour hand that reads local time and can be jumped quickly without hacking the movement is the ultimate in terms of travel functionality (with or without the ability to track home time, in my opinion), and there was a time not too long ago where it was thought that a watch with this feature deployed by microbrands in watches under $1,000 might be nothing less than a paradigm shift in the hobby. Well, we’re fully there, folks. The Miyota 9075 exists, and has been popping up in new watches from some of our favorite small brands for the better part of a year, and now Lorier has dropped it into a pair of GMT equipped watches, finally making them the dedicated travel companions many hoped they could be.  The Hyperion is what Lorier describes as “the archetypal GMT,” fitting a well established mold of classic travel watches by Rolex and others. It has deep vintage vibes, with a red and blue 24 hour bezel, gilt a...

Breitling Pays Tribute to Giants in the Sky with Navitimer B01 Chronograph 43 Boeing 747

When the Boeing 747 was revealed to the world in 1968, it instantly introduced a new era in air travel. Those in attendance, press and interested aviators alike, had no words for what they were looking at. The sheer size of the aircraft and its distinct upward curve above the flight deck was nothing like any other plane that was carrying passengers 30,000 feet up in the air at the time. It quickly became a coveted experience to travel in a Boeing 747, and that’s saying something considering this was a time where people got dressed up to fly in an airplane. Not like now, where sweatpants, a cozy hoodie, and noise canceling headphones are the norm. Flying back then was an event. The lore of the Boeing 747 only grew, as it was featured in many films including the 1973 James Bond flick, Live and Let Die. Even till this very day, the 747 is the aircraft of choice for the President of the United States. Introducing For The First Time Ever, The Boeing 747 But like all good things, they must come to an end. After 1,570 individual jets and 53 years of navigating the skies, the Boeing 747 has finally decided to retire. And to celebrate the original jumbo jet, Breitling has released a limited edition piece in partnership with Boeing called the Navitimer B01 Chronograph 43 Boeing 747. Breitling has a history that is deep rooted in aviation. Their very first designs, from dial layout to various complications, were created with pilots in mind. With both brands having a rich heritage i...
