U-Boat Watches - Back in 1942 the Officine Fontana was poised to produce a professional watch for the distinguished officers of its navys U-Boats. Though the project was ultimately scrapped, the distinctive original drawings, color samples and innovative materials were lovingly preserved for more than 60 years.
U-Boat models are unmistakable, with blocky crowns at the 9 o'clock position, thus situated in order to allow divers full wrist motion underwater, simple dials, often with Arabic Numerals at only the 4, 8 and 12 o'clock positions, and extremely oversized cases.
