SKELETON TOURBILLON

Crafted entirely in the heart of the Swiss Jura, the Chapter 4.1 T.V.D. Tourbillon by BA1110D is a refined expression of haute horlogerie. Encased in a 44mm Grade 5 titanium body, finished with a custom-developed DLC tantalum-grey coating by Positive Coating, this timepiece radiates understated strength and precision. Meticulous details, from mirror-polished, chamfered, and blued screws to the dual-sided gear train and rolled pivots : highlight the art of fine watchmaking.

At its core lies a hand-wound tourbillon movement, developed in La Chaux-de-Fonds by renowned master watchmaker Olivier Mory. Beating at 21,600 vibrations per hour, the tourbillon cage completes one rotation every 60 seconds and boasts an extraordinary 100 hour power reserve: more than four days of uninterrupted elegance.

The domed sapphire crystal with double anti-reflective coating and a semi-open dial reveals the technical beauty within. White Super-Luminova hands offer legibility with luminous poise, while the watch’s signature crown, positioned at 4 o’clock, is engraved with the BA111OD emblem.

Paired with a luxurious Italian-made Saffiano calf leather strap in midnight blue stitching, the Chapter 4.1 T.V.D. is as refined on the wrist as it is in concept.
