Sniper Proof

The yellow crystal had the purpose of dimming the luminous radium numerals which could give away the position of the soldier in the trenches to a sniper.

The most scientific

The case design of the Waltham Field & Marine was the most scientific of its epoch. This contemporary model draws inspiration from the original Depollier case and bayonet crown patents but is executed with a contemporary and improved construction . The crown-caseback-bezel tripych now guarantees a water resistance of 1000ft-300m which gives a new meaning to the “Marine” designation in the name of this significant timepiece.

The first waterproof watch

As tested by the US Army Signal Corps Laboratory and the US Bureau of Standards in 1918. A watch which helped define a nation and  the future of watchmaking history.

The Fishbowl Mark

In 1920 Charles Depollier registered the famous fishbowl trademark to identify his waterproof watches. This distinctive mark now identifies all Waltham waterproof watches.

The Field & Marine Saga

The book ""The Inconvenient Truth about the World's First Waterproof Watch", by NAWCC awarded Waltham and WWI watches historian Stan Czubernat, documents the story of the ingenious Charles Depollier and his waterproof wristwatch technology. His collaboration with Waltham resulted in the first waterproof watch, the Waltham Field & Marine.

Why should you own this watch?

The first

In 1918 the Field & Marine became the first waterproof watch. Ten years before any other manufacturer. This makes it a historically significant and collectible watch.

Bayonet crown

The only watch on the market today with a bayonet crown. A uniquely robust and user friendly technology from the beginning of the 20th Century.

Hall of Fame

The Field & Marine is displayed in the permanent exhibition of the Musée international d'Horlogerie in La Chaux-de-Fonds. The hall of fame of horology.

Extremely Rare

The original has been missing from the record of American WWI wrist watches era for more than 50 years. This limited edition of 25pcs will be a future collectible
