Description:
The BA111OD Chapter 4.5 TVD 40mm Tourbillon brings the technical architecture of the Chapter 4 collection into a more compact and refined format while preserving its mechanical power and contemporary identity.

At its heart beats the hand-wound BA.01 tourbillon caliber, equipped with a variable inertia balance and delivering an impressive 100-hour power reserve. Operating at 3 Hz, it ensures chronometric stability and consistent precision, positioning the model within independent haute horlogerie.

The Grade 5 titanium case with anthracite gun metal DLC coating combines extreme lightness, durability and cutting-edge aesthetics. With a 40 mm diameter and only 11 mm thickness (excluding crystal), it offers elegant and balanced wrist presence.

The semi-open dial reveals part of the mechanical architecture, reinforcing its instrumental character. The white SuperLuminova hands ensure optimal legibility in low-light conditions.

With 2000 Gauss magnetic resistance and 5000G shock resistance, the watch demonstrates exceptional structural robustness despite its high complication.

The Italian-made Saffiano leather strap with night blue stitching adds refined contrast and sophistication, completing a timepiece that merges engineering, exclusivity and modern design.

The BA111OD Chapter 4.5 TVD is a statement of contemporary Swiss mechanical innovation in a more versatile size, ideal for collectors seeking high complication with refined proportions.
