The Holton Professional (black dial model 101-001-R06) 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 on the case back.
The Holton Professional series is the first military issued watch from a British company in over ten years and prior to being approved, was the subject of intense testing, surviving some of the most hostile conditions imaginable.
The Brief: capable of prolongued exposure to water and dust, durable, shock resistant, clear visibility day or night, unidirectional timing bezel operable with a gloved hand, easy strap changes and comfortable strapping options that don't break.
The specification of the bezel gives a perfect insight into the level of detail required for the project to be successful.
A precise 120 click high grip bezel houses a stainless steel insert precisely embossed with hours and minutes indentations then flooded with high grade C3 SuperLuminova. The hobnail outer knurling is slightly higher than the insert to form a high grip surface for trustworthy operation even when using the palm of a wet gloved hand. Both components are matt bead blasted, hardened to 1200HV (Vickers hardness scale) then a 0.8 micron PVD coating is applied whose hardness matches that of the stainless steel components.
N.B. this bezel is unapologetically fit for purpose. Please be aware it is likely to catch or wear shirt cuffs etc.
Straps are easily changed and secured via solid steel screw in bars operated with a five lobe tool and matching socket in the strap bar ends.
The recessed crown sits neatly out of harms way at 4H whilst retaining the immense water protection afforded by our proprietary triple seals. An additional screw down mechanism locks the crown into the case. The last three photos are stills taken from a video of a Holton and a Kimmeridge strapped to an ROV in the Gulf of Mexico in March 2020, still working at 3900ft - almost 3/4 mile underwater.
