This beauty is a vintage diving watch from the Swiss manufacturer Sexima from the 1970s.

Technically this watch is very special due to the helium valve in the winding crown. This important component ensured that the overpressure that was generated during diving was able to escape through that tiny hole. Without the helium valve, there is a great danger that the watch glass will burst due to the enormous overpressure. Even well-known professional diving watches did not have such a helium valve.

Another special feature of this Sexima is the bakelite bezel, which has been perfectly preserved. The bezel has rich colors and is divided into a wine red and a light blue half. The black dial is immaculately preserved and has a nice contrast thanks to the creamy color of the hour markers and hands. The luminous material is tritium. At 6 o'clock the dial is marked with "T SWISS MADE T". The square date window is at 3 o'clock.

The stainless steel case has only slight signs of wear. The engravings on the case back are intact and clearly readable. The winding crown is screwed down. The Sexima is powered by an Incablock automatic movement that runs flawlessly and precisely.
