Nauticfish German Made 1000 Meter Automatic Pro Divers Watch with AR Sapphire Crystal #Thusunt-swarz NauticFish Thusunt - The new generation. The Old High German word thûsunt (thousand) stands for the outstanding reliability and water resistance of over 1000 meters of the new NauticFish generation. The goal was to realize a consensus between high reliability, modern functionality and retro-oriented design. The Thusunt has not been developed for the mainstream market as much more we see the series as a specialty among the diving watches. The dial impresses with its unusual used-style color sequence, the pillow-shaped case with its dimensions of 43x43mm leaves nothing to be desired in the wearing comfort. The excellent readability is ensured by the convex-loupe AR sapphire crystal with an enlargement factor of approx. 1.3. Further technical highlights such as the automatic PVD coated helium valve or the crown seal system perfect the performance of the Thusunt. The movement used to power the watch is the Swiss Made ETA 2824-2 automatic with 25 jewels. The watch comes with a leather strap, and a second silicone strap.
