Professional diver’s watch
The EDOX Hydro-Sub is a Swiss-made automatic chronometer built for serious underwater use. Its 300 m water resistance and unidirectional rotating bezel meet the core requirements of professional divers. A screw-down crown with a double O-ring seal reinforces the case integrity at depth. The 42.00 mm stainless steel case houses the calibre 806 movement.
Sapphire crystal and deployment clasp
The domed sapphire crystal resists scratches and maintains clarity under pressure. A stainless steel bracelet with a deployment clasp secures the watch during active movement. The date window at three o’clock adds daily utility without cluttering the black dial. Index markers and analog hands provide instant legibility in low light.
Depth rating and mechanical headroom
The 300 m rating covers saturation diving and prolonged immersion far beyond recreational limits. Automatic winding removes the need for battery changes during extended trips. The chronometer-certified calibre 806 delivers consistent timekeeping across temperature shifts. Buyers needing a helium escape valve or a depth sensor will not find those functions here.

Questions about this item
How often does the automatic caliber 806 movement require servicing?
The automatic caliber 806 movement typically needs professional servicing every three to five years to maintain chronometer accuracy and ensure the movement oils remain effective.
Which component limits the depth rating during prolonged dives?
The screw-down crown with its double O-ring seal is the critical barrier; it must be fully tightened before every dive to maintain the 300m water resistance under sustained pressure.
Does the stainless steel case and bracelet become uncomfortably hot during all-day wear?
The 42.00 mm stainless steel case and bracelet stay close to skin temperature in normal conditions; they do not generate heat and feel neutral during continuous daily wear.
