CTSFO limited edition Holton quartz


The Holton Professional was originally developed in response to a request from a specialist branch of the British military who demanded a fit-for-purpose professional dive watch. Since its launch five years ago, it has proven its worth as the watch of choice for military and law enforcement personnel, with thousands worn daily worldwide.

120 click high grip bezel with a hardened black stainless steel insert with pale yellow-green C3 SuperLuminova. The hobnail knurling around the edge is slightly higher than the insert to create a high grip surface for trustworthy operation even when using the palm of a wet/gloved hand. 
The recessed screw-down crown is located out of harm's way at 4H ensuring it won't dig into the wrist and can't get caught or damaged.

Beadblasted dark grey 316L stainless case with black bezel insert and C3 Superluminova markings
9H-3H 43mm excluding crown
12H-6H - 52mm max to tip of case shoulders
Maximum thickness 12mm
Easy to read at a glance day or night with clarity. The hour markers are bold pyramids reminiscent of 1970s military dive watches, brought up to date with our trademark 12-3-6-9 cardinal graphics, all printed in C3 Superluminova.

Clear differentiation between hours, minutes and seconds for minimal chance of confusion. The stubby ‘sword’ hour hand and slender parallel minutes hand are both filled with C3 Superluminova.

Flat sapphire glass with internal anti reflective coating to minimise glare for perfect visibility in all light conditions. Fitted using a black sealing ring to match the case.


5-jewel Swiss made Ronda 715 quartz movement with 4yr battery life and low battery warning. Housed inside our shock protection movement housing with elastomer shock absorbers.

Strap bars:
Solid steel strap bars that screw directly into the case shoulders, driven by a 5-lobe head so that the driver (included with the watch) can't slip or climb out, ensuring simple and fast strap changes whilst also providing maximum security

Bolted down using hex bolts creating a perfect compression seal and correct tension for the shock absorption system. Multiple surfaces minimise skin contact for comfort. Caseback engraving will always be vertical as shown.


We design and re-design every component to make watches that are fundamentally fit-for-purpose, minimising or eliminating typical points of failure such as spring bars breaking, straps snapping, or watches leaking - all potentially catastrophic failures.

Any watches damaged in service can be repaired quickly and economically at our in-house workshop in Poole and returned to service with the minimum of disruption.

Not only is our servicing world class, the warranty has no small print. It’s honest, comprehensive, and straightforward. The whole watch is covered for 5 years, not just the movement. The only exclusions are accidental damage, the battery and wear & tear.
