A great duo for divers : on the left, the Deep One, on the right, the Aquatimer, the only diver’s watch water-resistant to 2000 m. Deep One is an automatic watch that is water-resistant to 100 m and fitted with functions specially designed for professional divers. Thanks to an interior rotating ring operated with the crown at 2 o’clock, it can record the length of a dive and the depth to 45 m. The bathometer is operated with the crown-valve at 4 o’clock.These automatic precision instruments come in a titanium case from the GST line, and on a matching bracelet. A Velcro® strap is included so they can be worn on a diving suit.
