Chapter 4 Skeleton Tourbillon Ice White

BA111OD is back with another statement piece, the Chapter 4 Skeleton Tourbillon Ice White, a watch that strips away the unnecessary and leaves only pure mechanics on display. Since 2019, the Neuchâtel-based brand has been carving out a space in the crowded world of Swiss watchmaking by mixing traditional savoir-faire with a refreshing sense of accessibility. With this latest release, it leans fully into transparency.

The 40mm stainless steel case, complete with the brand’s offbeat 4 o’clock crown, feels sharp yet wearable. The fully openworked dial reveals everything: bridges, gears, and, of course, the star of the show, a tourbillon at 7 o’clock. It’s a complication that needs no introduction, Abraham-Louis Breguet’s 1801 invention remains one of the purest expressions of watchmaking mastery. Here, it’s executed by Olivier Mory, the Jura Arc watchmaker behind many of BA111OD’s movements, and it comes with a hand-wound skeleton caliber offering an impressive 100-hour power reserve.

And while the Ice White is all about showing the movement, it doesn’t forget versatility. You can dress it up with a smooth ceramic strap, keep it sporty with white rubber, or lean into the watch’s industrial character with a steel bracelet. It’s modern, technical, and unapologetically mechanical, a piece that proves BA111OD is still very much in the business of making complications exciting, wearable, and, above all, approachable.
