What does 50 m water resistance mean?

From 50 m (5 bar) water contact is fine — showering is possible, swimming from 100 m. The metre rating refers to the test pressure of the water-resistance test, not a diving depth.

Description

U-Boat Classico 30 Lady Aquamarine with the reference 8900.

Ilvo Fontana, a skilled worker in precision instruments, received a prestigious commission from the Italian Navy. He was to design a new watch for their pilots. This challenge was to meet the high quality standards of the Navy and very precise technical specifications, but above all it was to guarantee maximum visibility and reliability in any light or weather conditions. However, unfortunate circumstances at the time did not allow this to happen. In 2000, Italo Fontana, Ilvo's grandson, came across the precious designs which became his inspiration for the first submarine watch.
