As Sharp as Your Racing Line

The APEX Carbon is a 42mm Swiss Made chronograph with a carbon fiber dial, tachymeter bezel, sapphire crystal, and 100 metres of water resistance. It houses a Swiss-made Ronda 3540.D quartz movement with 1/10th-of-a-second chronograph precision.

Movement

The Ronda 3540.D is a Swiss-made quartz calibre with a 1/10th-of-a-second chronograph function. Three subdials display chronograph hours at 12 o'clock, minutes at 9 o'clock, and running seconds at 6 o'clock. The anodised aluminium tachymeter bezel allows speed-over-distance calculation, a function widely used in professional motorsport timing.

Dial

The APEX Carbon dial features a genuine carbon fiber weave with cut-through numerals and applied hour markers. Each dial carries a unique weave pattern inherent to the material. All markers and the baton-shaped hands carry Swiss Super-LumiNova for low-light legibility. A date window is positioned at 6 o'clock. The dial sits beneath a scratch-resistant sapphire crystal with multi-layer anti-reflective coating.

Case

The case is 316L stainless steel, measuring 42mm in diameter and 12mm in thickness, with a 51mm lug-to-lug span. It combines brushed, polished, and chamfered finishing. A screw-in crown and screw-in chronograph pushers at 2 and 4 o'clock secure the 100m water resistance rating.
