How do I identify a military issue watch?

Look for specific government or service markings stamped onto the case back, such as broad arrows or serial numbers. Many military pieces also utilise high-contrast black dials and luminous numerals designed for maximum legibility in low light.

Are these watches waterproof?

Most vintage service watches lack modern rubber gaskets and screw-down crowns associated with contemporary diving equipment. Exposure to moisture should be avoided unless the piece has been professionally sealed and tested. Dust and moisture resistance in period pieces relied solely on tight-fitting case backs and crystal bezels.

Can I wear a trench watch daily?

While these pieces were built for active service, their age makes them susceptible to modern impacts and environmental hazards. Gentle, occasional wear suits them best. Regular servicing by a specialist horologist helps preserve the internal brass and steel components for future years.
