Introducing – The Brellum Pandial Power Reserve Black Titanium Chronometer LE

Timex Launches “Timex Atelier” with the New Marine M1a Worn & Wound
Timex Launches “Timex Atelier” Sep 25, 2025

Timex Launches “Timex Atelier” with the New Marine M1a

Timex is continuing its experiment with higher-end horology with its latest release, the Timex Atelier Marine M1a, which the brand describes as a spiritual successor to the Giorgio Galli series and the first watch in the new Timex Atelier line. The Galli series garnered attention for being “luxury Timex,” with minimalist design, higher-grade cases - like the titanium Giorgio Galli S2Ti - and, biggest of all, that prestigious “Swiss-made” label. Timex says the Marine M1a is the “next chapter” in the brand’s history as it continues to build watches in Switzerland with higher-end materials and movements than typical Timex watches. In the case of the Marine M1a, that means a 41mm skeletonized stainless-steel case with an iron-plating coated midcase, a brushed-steel bracelet, a ceramic bezel, Superlominva-filled indices, and an enamel dial. The watch is powered by a Catena SA100 automatic movement finished with Geneva stripes and perlage that you can get an easy look at through the watch’s exhibition caseback. It’s a bit more conservative in design than the retro-minimalism of the Galli watches, and, in the words of Timex’s chief creative director, Giorgio Galli himself, was “not designed to impress at a glance,” but to “be discovered, slowly, over time.” There are many details to discover over time. A signed crown, silver-applied indices, a movement rotor engraved with “Timex Atelier.” But the watch isn’t just aesthetic-oriented - with a...

Hands-On: Renaud Tixier Introduces the Monday Organica by Oliver Vaucher, a Visually Stunning Solution to a Horological Problem Worn & Wound

Hands-On: Renaud Tixier Introduces the Monday Organica by Oliver Vaucher, a Visually Stunning Solution to a Horological Problem

Our first meeting at thai year’s Geneva Watch Days might turn out to be one of the best. Renaud Tixier launched during Watches & Wonders week of 2024 with a bold idea: seven revolutionary horological creations, released in a series of watches that will take nearly two decades to complete. Their first watch, the Monday (guess what the others will be called) is an attempt to solve the problem of the micro-rotor. While these small, often heavy rotors are wonderful for creating automatic watches that are nearly as thin as manually wound watches (and for showing off elaborate movement decoration) they are inherently inefficient. The Monday seeks to solve that problem with a completely new horological invention.  The Renaud of Renaud Tixier is Dominique Renaud, the legendary watchmaker who was one half of the famed Renaud & Papi firm, who carved out a niche for themselves in the 1980s and 90s by creating ultra high end complications for the most prestigious brands. Renaud Tixier works along similar lines, but of course is a brand unto itself, and Renaud seems free to pursue whatever horological problem solving might be of interest to him. These watches, while incredibly beautiful, are ultimately for the hardcore movement nerds among us.  The innovation of this first Renaud Tixier caliber is in the behavior of the micro-rotor. The brand refers to it as “the Dancer” because of the way the mechanism seems to dance at even the slightest jostle. Renaud Tixier’s micro-rotor ...

Diving with the Ball Watch Engineer Master II Diver Chronometer

When Ball Watch asked Dietmar Fuchs to test dive one of the company’s newest watches, the Engineer Master II Diver Chronometer, he hesitated at first.

So he dove in and now shares his experience and thoughts on the watch here.
