The order that created a branch: Admiralty Order 857/52

Most watch names are invented in a marketing meeting. Ours was written in an Admiralty office in 1952.

By the end of the Second World War, the Royal Navy had learned — at great cost — that ships and harbours could be crippled by what lay beneath the surface. Mines fixed to hulls, unexploded ordnance in harbour mud, blocked approaches that had to be swum, inspected, and cleared by hand. The men who did this work during the war, notably the harbour clearance parties — the “P-parties” that cleared liberated ports of explosives — proved that diving was no longer a supporting trade. It was a discipline of its own.

In 1952, an Admiralty order formally established the Royal Navy Clearance Diving Branch — turning wartime improvisation into a permanent profession, with its own training, its own standards, and its own crest: the diving helmet flanked by dolphins, beneath the crown.

What the branch became

A clearance diver's work is the unglamorous end of naval operations: explosive ordnance disposal, mine countermeasures, deep search and recovery, underwater repairs on ships' hulls. It is methodical, cold, dark work where the margin for error is zero — and where knowing how long you have been down, and how long you have left, is not a convenience. It is survival.

That is why the branch's history is inseparable from the history of its equipment — including the watches on its divers' wrists. Divers of the 1950s and '60s were issued military Submariners — the watches collectors now call MilSubs — built to Admiralty requirements for absolute legibility and reliability under pressure.

Why we put a filing number on a dial

857/52 reads like what it is: an entry in a ledger. Order 857 of 1952. We chose it because the story of the branch does not need embellishing — the most meaningful name we could give our diver's watch was the piece of paper that made the profession exist.

The 857/52 Clearance Diver 200M is our tribute to — and continuation of — that lineage: Swiss-made mechanical movement, 200 m water resistance, aged lume, and the branch crest engraved where the diver would never see it, but would always know it was there.
