Hands-On: the Haim Legacy Automatic Collection

Once a small brand has gained some traction, they usually do one of two things: dig deep into a hero product, or continue to delve into their brand ethos to create new things. Haim Watch Company seems to be steadfastly in the latter category. Following initial releases like the L2 and the Descent which featured design codes that clearly linked them together, one would be forgiven for assuming they’d mine these models for all they’re worth. But instead, the Chicago-based brand is building new styles that only expand the definition of what a Haim watch can be. Their latest collection is their Legacy Automatic. Coming in three colorways, this line-up shows a break from the previous generations of Haim watches and nods at real growth towards higher-quality, and more eye-catching designs. Compare, for example, the original Legacy collection to the Legacy Automatic. While the former has a fairly inconspicuous charm to it, you can begin to see that Haim is ready to cement itself as a brand that can take risks and maintain its mission statement as a microbrand that brings a luxury feel to a relatively affordable price point.  The Legacy Automatic references boast a lot of firsts for the brand, so I’d like to start with those as a sort of headliner for the collection. For one, it’s the first time and date-only design within the Legacy line-up. Not only that, but it’s Haim’s first custom designed caliber (more on what that really means soon) and is the first watch in Ha...

The Schofield Watch Company Introduces a New Case Shape and Size with their Field GMT

For the past 15 years, UK based Schofield Watch Company has been making watches using the same case shape and dimensions, with various color and finishing details. For 2024 they are launching a brand-new case and size, as well as a new complication. Introducing the Light, a field watch with a GMT function, which retains Schofield’s design esthetics, but at a size that should appeal to today’s sensibilities.  There are two models within the Light collection. Both feature a two-piece 40mm media-blasted case with a vertically brushed bezel, and the movement powering them is the relatively new Seiko NH34 GMT. They also have domed box sapphire crystals and case backs that feature lighthouse artwork printed on a mineral glass, through which you can see parts of the movement.   The aptly named The Light One, has a light gray step dial that features a cream outer ring with black printed numerals. The hour and minute hands are painted dark for contrast, with a light colored 24hr GMT lollipop hand turning within the inner stepped portion. The Dark One, in contrast, has a darker gray center dial, with a black stepped ring and white numerals. The main hands are light gray, the lollipop GMT hand is dark gray, and the case is entirely coated in black PVD. The text, branding and logo on the dials are very discreetly printed and there is no 24hr track, which makes reading the second time zone a little challenging. Therefore, a little commitment to understanding how to read the GMT ...

First Look – The Grand Seiko Pink Snowflake SBGA497, Celebrating 20 Years of the 9R Spring Drive Calibre

Khanjar and Qaboos Rolexes: Are they the Vintage Watch Industry’s Blood Diamonds? (Updated with New Information) – Reprise

Increasing demand for timepieces, especially Rolexes, with the Omani emblem is understandable given the high quality, good condition, demonstrable provenance, and rarity of most of these watches, combined with the fact that they had often been presented to their first owners in the 1970s by Sultan Qaboos in person as a token of gratitude for services rendered. Colin Alexander Smith takes a very close look at the meaning behind these rare timepieces and in this updated version of the article debunks one theory behind the dial symbol.

Watches, Stories, & Gear: Breaking Down Sartory Billard’s New Movement, Tracking the Northern Lights, and Unboxing the Apple Vision Pro

“Watches, Stories, and Gear” is a roundup of our favorite content, watch or otherwise, from around the internet. Here, we support other creators, explore interesting content that inspires us, and put a spotlight on causes we believe in. Oh, and any gear we happen to be digging on this week. We love gear. Share your story ideas or interesting finds by emailing us at info@wornandwound.com Sartory Billard’s SB08 Movement Gets Broken Down at Revolution  Our friends at Revolution have what is easily the most interesting technical watchmaking article we’ve seen in quite some time this week. In part 2 of their examination of Sartory Billard’s SB08 caliber, Cheryl Chia takes a deep dive into the ongoing work in developing this complicated, unique, and frankly quite exciting movement that features jumping hours and jumping minutes and a tourbillon. Part 1 of the three-part series was published in October, and serves as a higher level overview of the idea behind the SB08, and a little background on the Sartory Billard brand, while this latest article digs a bit more into the weeds of the mechanics, and some of the inherent challenges in developing a movement that requires so much power. We don’t often get a view into movement design in what amounts to real time, so this is a must read for anyone with an interest in the highly complicated mechanical calibers. Chia takes us through some fairly complex watchmaking problem solving, and provides a taste of what finished watc...
