How do I identify a military issue watch?

Military issue watches usually display specific government engravings, broad arrow marks, or serial numbers on the case back. These stamps denote the branch of service, such as RAF or army trade patterns. Contrasting dials with 24-hour markers or specialised department codes also indicate official military provenance rather than civilian production.

Can I wear a vintage military watch daily?

Many collectors wear these watches regularly, provided they receive proper care and routine servicing by a qualified horologist. Mechanical movements from the mid-twentieth century remain remarkably resilient. However, because most vintage models lack modern waterproof seals, owners should keep them away from moisture and heavy impacts.

What does Dirty Dozen mean?

The Dirty Dozen refers to a specific group of twelve Swiss watch manufacturers who supplied standardised waterproof wristwatches to the British Ministry of Defence during the Second World War. These pieces share specific military specifications including black dials, Arabic numerals, sub-seconds registers, and stainless steel or nickel-chromium cases.

Why do some military watches have shrapnel guards?

Shrapnel guards were added to early trench watches during the First World War to prevent the fragile glass crystal from shattering during combat. Soldiers strapped these protective metal grids directly over the watch face. Finding a period piece that retains its original guard is uncommon, as many were removed when owners returned to civilian life.
