The Holton Professional was developed in response to a request from a specialist branch of the military who demanded a fit-for-purpose professional watch capable of a life in the field. The '002 green dial model is identical in specification but does not carry the nato stock number.

Specification:

Bezel: high grip, uni directional divers bezel case hardened to 1200HV Vickers hardness with matt PVD coating whose hardness matches that of the hardened bezel. Highly resistant to marking and provides an outer layer of protection for the watch. The high grip texture enables the bezel to be turned by gripping the sides or pressing downwards and the fine hobnail pattern ensures the bezel can't be caught on anything, turning it accidentally

Case: 316L stainless, anti reflective gunmetal PVD, treated with an anti-fingerprint coating that naturally repels mud and grime. PVD thickness 0.8 microns so it wears beautifully for years - the maximum possible thickness without loss of definition on case detailing (approx twice the industry standard thickness). Every watch is individually pressure tested to 200m at several points during production 

Crown: easy to use yet highly protected. Deeply recessed, screws down into watch case, triple sealed, hobnail knurling for secure grip, 4H position keeps it out of harms way

Dial: easy to read at a glance day or night with a military bearing that’s relevant and familiar. The hour markers are bold C3-coated parallelograms reminiscent of 1970s military dive watches, brought up to date with our trademark 12-3-6-9 cardinal graphics, with a white triangle at 12H to help orientate the watch when it’s dark

Hands: clear differentiation between hours, minutes and seconds hands with minimal chance of confusion. Short stubby ‘sword’ hour hand, long slender parallel minutes hand with pointed tip that reaches precisely to the minute markers. The seconds hand has a fine amber painted tip and C3 filled arrow head counterbalanced by a dark gunmetal ‘lollipop’

Crystal: bevelled 2mm sapphire with anti reflective coating applied to the inner surface to minimise glare for perfect visibility in all light conditions. To pass QC, every crystal must be capable of withstanding an impact applied 3 times by a 17mm steel ball dropped from 0.5m

Movement: Swiss Ronda calibre 715 with low-battery/end of life indicator that prevents the watch being issued with a low battery. It is housed inside a proprietary shock protection system consisting of a steel housing suspended by elastomer shock absorbers. Projected battery life is approximately 3 years

Strap fixing: 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 - no spring-bars to break

Caseback: 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 and bolting the case down ensures the case back logo and detailing are always aligned perfectly
