Overview
Carbon nanofibre baseplate execution
Introduced in 2005, the V2 replaced the grade 5 titanium baseplate of the V1 with carbon nanofibre. The material was selected for dimensional stability: differing temperature coefficients between movement components can disturb the going train, and a thermally stable baseplate provides a consistent foundation beneath the split-seconds mechanism.
The V2 also incorporated titanium gear wheels and levers to reduce inertia, and a revised generation of split-seconds components.

Design and engineering
- Carbon nanofibre baseplateSelected for dimensional stability under temperature variation.
- Reduced hand jumpTitanium gear wheels and levers reduce inertia, substantially eliminating the initial jump of the chronograph seconds hand on starting.
- Reduced energy drawRedesigned split-seconds components reduce friction on the spindle, decreasing energy consumption by approximately 50%.
- Titanium handsSubstituted for steel following the discovery of static charge accumulation above the carbon nanofibre baseplate; the change was retrofitted to delivered watches.
- Chronograph controlsStart and stop at 8 o’clock, reset at 10 o’clock, split-seconds at 4 o’clock, with two central chronograph seconds hands and the 30-minute counter at 9.
- Function selectorCrown-centre pusher selecting winding, neutral and hand-setting, shown by the W–N–H indicator at 3 o’clock.
