The Davosa Ternos Professional series is specially designed to meet the exigent needs of extreme divers. It displays a very high water resistance of 50 ATM, it is particularly robustly built, and it has an automatic helium valve set at 9 o’clock, which is essential when using a decompression chamber in very deep water. The three new DAVOSA Ternos Professional models are a modern addition to DAVOSA’s popular series, adding a dash of lifestyle to the functional, professional diving collection, effectively bridging the gap between technology and design. 

• PERSPECTIVE FOR PROFESSIONALS - For the Ternos Professional Nebulous Automatic, the mechanics of the watch have been made visible thanks to a semi-transparent sapphire crystal. It lies directly on the movement and is fixed by the skeletonised dial ring, whose indexes filled with SuperLumiNova® BGW9 together with the hand play ensure optimal readability.
• VALUES YOU CAN RELY ON - The water resistance to 500 metres (50 ATM) allows for larger expeditions to deeper underwater destinations. Particularly resistant materials, such as the anti-reflective sapphire crystal with its special thickness and the fully threaded screw-in case back, ensure maximum reliability. As part of the product development process, the Ternos Professional passed a wide range of tests that go beyond guaranteed water resistance. The safety of the diver is paramount. The water resistance of 50 ATM is the unique selling point of the Ternos Professional series.
• CONVENIENT ADJUSTMENT - Another highlight of this model is the redesigned TriaLink stainless steel metal bracelet. The individually screwed solid bracelet links end on both sides in a folding clasp newly developed by DAVOSA, which with two side pushers and a WaveSlide fine adjustment inside the clasp enables convenient adjustment - without any additional tools.
