The Watch for Action Heroes: Panerai Luminor Submersible 1950 Amagnetic

We don’t think about magnetic fields often and though they are thoroughly pervasive in our high technology environments, we tend to think of magnets as these little buttons of fun used to “hover and drag” metal cars across table tops. It’s time we grow out of childish notions and understand that magnetic fields are generated […]

Watches & Wonders: Bulgari Launches an Octo Finissimo in 37mm

The Bulgari Octo Finissimo is a certifiably unique watch that you can identify on someone’s wrist from across a room. Part of this is because of its exotic integrated design, and the other part is that they are kind of huge, despite being very thin. That contrast has always been part of the appeal, but also part of the problem. For years, the Octo Finissimo has represented an avant-garde take on modern watch design. Thin, minimal, architectural, and kind of brutal, it exists as a distant relative of a Genta-era idea, but pushed into something more experimental. It has also built its reputation on technical achievement, frequently contending for the world’s thinnest watch, and holding that title more than once over the last decade. But this year, Bulgari isn’t focused on thinness. Instead, they’ve turned their attention to something far more practical: wearability. For the first time since the line launched in 2014, Bulgari has introduced a smaller “consumer” model, bringing the Octo Finissimo down to 37mm. On paper, that might not sound like much. In practice, it changes everything. The standard 40mm models were always a bit deceptive. While 40mm is not particularly large for a round watch, the Octo Finissimo is anything but round. These watches are essentially flat squares with wide integrated lugs, creating a large corner-to-corner span and a cuff-like presence on the wrist. The result is a watch that wears significantly larger than its width suggests. It’s...

A History and Guide – How to Use a Dive Bezel

John Scott Haldane had a problem. Britain’s Royal Navy had commissioned the Scottish physiologist to find a solution for a unique problem facing their divers: decompression. Known since the mid-19th century, decompression sickness (DCS) posed a serious risk for divers and laborers working in pressurized environments, such as caissons. It was his job to develop a set of decompression tables for safe diving operations. It boils down to how gases act under pressure. When breathing a gas mixture at depth - for the sake of simplicity, we will say compressed air, or approximately 78% nitrogen and 21% oxygen, with the rest being inert gases - the oxygen is used up by the body, and the nitrogen is absorbed into the bloodstream. This build-up will dissolve as it is effectively off-gassed, as it does when each of us breathes here on the surface. Enter pressure. Should a diver undergo a rapid change in pressure, such as by ascending too quickly, the nitrogen will separate from the blood and form bubbles in the tissues and joints. The resulting pain has a habit of contorting its victims, giving DCS its more readily-known nickname of “the bends.” John Scott Haldane had a problem.

A Comprehensive Look At Mechanical Depth Gauge Watches

Depth matters. And as experienced divers often like to go deep for as long as possible, decompression is a serious issue. The problem with mechanical depth gauges on watches is that they are usually either precise at depth (but not in the 12-meter decompression zone) or in the decompression zone (but not at depth). Dietmar Fuchs takes a deep dive into mechanical depth gauge watches and shares his thoughts and experiences here.

Best of 2024: Complications

Perhaps echoing the paucity of highlights in indie watchmaking, the best complications of 2024 were not numerous, but those that stood out were outstanding. Vacheron Constantin, for instance, unveiled the most complicated watch ever, while Bovet solved the longstanding problem of summer time across continents in an enormous (and enormously expensive) wristwatch. Here’s the team’s take on the best complications of the year. A. Lange & Söhne Datograph Handwerkskunst – Brandon Moore The iconic Datograph turned 25 this year, and collectors were treated to three different limited edition variants to mark the occasion. We were first introduced to the Datograph Perpetual Tourbillon Honeygold “Lumen” and the Datograph Up/Down 25th Anniversary at Watches & Wonders, but Lange was arguably saving the best for last: the first Datograph to receive the brand’s artisanal Handwerkskunst treatment. Featuring a hand-engraved tremblage dial and limited to just 25 pieces, the Datograph Handwerkskunst is a fitting way to celebrate a quarter-century of being best-in-class. While not particularly creative, this very-limited edition captures both the magic of Lange and its Datograph perfectly. Bovet Récital 28 Prowess 1 – SJX The introduction to our story on the watch sums it up best: “The Bovet Récital 28 Prowess 1 is an ingenious solution to an age-old problem: accounting for daylight saving time (also known as summer time) in a multi-timezone wristwatch… the solution is e...

[VIDEO] Mail Time: Unboxing Watches from Gavox, Venezianico, and Ardio

Here at the Worn & Wound office, watches arrive at our doorstep everyday. So many watches are coming in, not everyone in the office can possibly see all of them. It’s a nice problem to have, and presents an opportunity for members of the team to give us their immediate, honest reactions to new watches they’ve never seen before. In this Surprise Unboxing, Zach Weiss and Zach Kazan look at a selection of watches they’ve never seen before, have varying levels of familiarity with, and give you their honest first impressions.  In this episode, Zach Weiss takes a look at a pair of new sports watches from Ardio (recently reviewed by Meg Tocci right here), one of which has a surprisingly detailed textured dial that punches well above its weight class. Zach Kazan struggles with the pronunciation of a diver from Italian brand Venezianico, but is truly impressed by its aventurine dial. And then they look at a pair of watches from Gavox, an old-school microbrand that recently upgraded their Avidiver with a GMT movement.  The post [VIDEO] Mail Time: Unboxing Watches from Gavox, Venezianico, and Ardio appeared first on Worn & Wound.
