British watchmaker, Christopher has teamed up with Swiss skeleton watch pioneers, Armin Strom to create the brand’s most ambitious-looking diver to date.

This is the new C60 Apex Limited Edition watch which comes five years after the release of the Caliber SH21, Britain’s first commercially viable movement in half a decade.

The C60 Apex Limited Edition celebrates this milestone with use of a special architectural aesthetic that reveals as much of SH21 as possible.

The watch comes with features such as a Helium Escape Valve, power-reserve indicator and for the first time in CW’s diver family, an exhibition case-back.

This affords views of the decorated Caliber SH21 housed inside its 42mm in diameter, marine-grade Stainless steel, 300m water-resistant case.

A navy blue and orange color scheme with anodized orange power-reserve indicator itself sat on a 3D bridge at 9 o'clock take care of the watch’s sporty, semi-open-work dial -
while the SH21's exposed hour wheel is surrounded by vertically lined plating. The Apex's raised indexes and hands: brushed, polished and multi-faceted are filled with Grade X1 GL C1 SLN.

The dial is then topped with a museum-grade Sapphire crystal which is surrounded by a zirconia ceramic bezel diver’s bezel. It’s all very nice!

The SH21 is has a ton of cool design features such as its aluminum and tungsten construction. The tungsten used for its rotor for example has been hollowed-out and finished in anodized orange.

The Contrôle Officiel Suisse des Chronomètres certified SH21 is a twin barrel movement so can deliver up 120hrs of autonomy from a full wind.

The 100-piece Limited Edition is available in three variants one with a steel bracelet and two strap models. Prices are from 3,495GBP. You can preorder now for the end of September.

Thoughts? This is a pretty cool release; quite unexpected from CW who are better known for perhaps a more classic take on modern dive watches. What do you think?
