BA111OD Unveils the Chapter 4 Tourbillon GMT Limited Edition 2025

The young Swiss watch brand Ba111od, based in Neuchâtel, continues its ascent in haute horlogerie with the Chapter 4 Tourbillon GMT Limited Edition 2025. Limited to just 30 pieces, this new iteration builds on the 2024 Chapter 4.8 GMT Tourbillon Greenwich, reinterpreting its signature tourbillon and GMT complications in a refined, understated color scheme. A distinctive feature is its GMT display, which accounts for half-hour time zone increments, as seen in cities such as New Delhi. The dial comes in a sophisticated gray, enhanced by a delicate sunburst finish. It provides an elegant stage for the minute tourbillon at 4 o’clock, rotating under a V-shaped bridge, and the opposing GMT indication, designed in the form of a miniature globe. In the spirit of minimalism, the slender markers and hour and minute hands harmonize seamlessly with the color palette, allowing the two complications to take center stage.

Measuring 44mm in diameter, the case is crafted from lightweight yet resilient grade 5 titanium and treated with pink gold PVD coating. Despite its refined appearance, it is water-resistant to 50 meters and shock-protected up to 5,000 G. Characteristic design elements include a slim bezel that gives the dial ample room to shine and an unusually positioned crown at 4 o’clock. The sapphire case back reveals the finely finished manual-winding BA.01 caliber, conceived by renowned watchmaker Olivier Mory. Operating at 21,600 vibrations per hour, it offers an impressive power reserve of approximately 100 hours and is protected against magnetic fields.

The two-tone elegance of the watch is complemented by a gray nubuck leather strap. The Chapter 4 Tourbillon GMT Limited Edition 2025  is available for pre-order at Ba111od  for $10,900, with deliveries scheduled for spring 2026.
