How do I identify a true military watch?

Authentic service pieces typically bear government issue markings, such as broad arrow symbols or department codes, engraved on the case back. The dial design prioritizes legibility with high-contrast numerals and railway tracks for minute reading. Matching movement serial numbers and specific military nomenclature distinguish actual issued equipment from civilian models styled to look military.

What does Dirty Dozen mean?

The Dirty Dozen refers to a specific group of twelve Swiss watchmakers commissioned by the British Army to supply waterproof wristwatches during the later stages of the Second World War. These timepieces were marked with WWW on the reverse, standing for Watch, Wrist, Waterproof. Collectors prize this specific set because they represent a unified military standard adopted across multiple allied regiments.

How should I care for a vintage watch?

Vintage mechanical movements require gentle handling and regular servicing by a qualified horologist to ensure proper lubrication of gears and springs. Keeping the piece away from excessive moisture and strong magnetic fields preserves its operational longevity. Hand-wound mechanisms should be wound carefully at approximately the same time each day without forcing the crown past its natural stopping point.

Are these watches waterproof?

Original water resistance seals degrade significantly over decades, meaning historical military watches should be kept away from water entirely. Even pieces marked as waterproof during production no longer retain gaskets capable of excluding moisture today. Owners must remove the watch before swimming, showering or engaging in heavy downpours to prevent internal rust and dial damage.
