THE 1918 FIELD & MARINE Waterproof and Dustproof Watch
FIELD & MARINE
Engineered for the trenches. Built for a Lifetime.
The harsh conditions of WWI trenches required a water-resistant and mustard gas resistant watch which until then did not exist. The bayonet crown, clinched bezel and compressor case-back technology developed by Charles Depollier in collaboration with Waltham for this purpose, assured the first true water-resistance to a wristwatch in 1918. Still today, the Field & Marine is the only watch with a bayonet crown.
A watch born from American scientific and industrial ingenuity.
Field & Marine Dual Time
The first waterproof watch with 24h dual time and power reserve complications and a bicompax dial layout.
MAKING HISTORY. SINCE 1918
The original patent
The bayonet crown of the Field & Marine has been developed on the basis of the original patent granted on January 28th in 1919. In total four patents for screw down crowns have been filed by Depollier and Waltham team between 1917 and 1919.
BAYONET CROWN
A technology from the early 1900s and still today the most robust, reliable and user-friendly one. Together, the decompression case-back, the clinched bezel and the bayonet crown constitute the 30ATM waterproof construction of the Field & Marine.
