LEVMASTER SUB-PROFESSIONAL 300 HELIUM VALVE

This feature, much appreciated by professional divers, allows you to reach depths of up to 300 meters without problems. The bezel is unidirectional with 120 clicks and, as befits a professional instrument, unidirectional in an anti-clockwise direction, to prevent a casual and involuntary movement of the numbered bezel from extending the time limit for recovering decompression times during the ascent to the surface beyond the expected limit. The glass is obviously made of scratch-proof sapphire and treated with anti-reflective treatment on the inside, to prevent a line on the surface during sports use that cannot be repaired without replacing the glass. To make it easier to read the date at 3 o'clock, the glass also has a magnifying glass. The movement is automatic. The unidirectional bezel is made of ceramic. The crown, characterized by a functional knurling for easy grip and operation. The winding crown is screwed to the case and guarantees water resistance thanks to the gasket (1-2) as regards the helium expulsion valve, this will be activated automatically during surfacing from dives. The steel bracelet is provided with a comfortable and functional professional buckle that includes an additional extension link to be able to wear it over a neoprene wetsuit.
