Condition Report

The watch is presented in Grade A+ unworn condition. The bronze case shows the natural warm tone and character typical of this material, which may develop a unique patina over time depending on use and environment.

The black dial is clean and highly legible, with large luminous hour markers, date display and 24-hour subdial. The sapphire glass is in excellent condition. The original leather strap has a strong vintage-style appearance, matching the character of the watch, and fits a wrist up to approximately 22 cm.

The watch is rated 300 m water resistant, but no recent pressure test has been performed, therefore water resistance is not guaranteed.

Story & Heritage

U-Boat was created by Italo Fontana, inspired by historic Italian military watch concepts and by the idea of building watches with extreme personality. The brand became known for oversized cases, left-side crown systems, bold dials and a design language that is instantly recognizable.

The Sommerso collection represents U-Boat’s interpretation of the professional diver’s watch. The bronze case gives this model a special charm: unlike stainless steel, bronze evolves with time, gaining a unique patina that makes each watch personal to its owner. Combined with the large crown locking system, 300 m diver specification and strong black dial, this watch carries both tool-watch spirit and Italian luxury expression.

A remarkable piece for collectors looking for a modern bronze diver with presence, originality and unmistakable U-Boat identity.
