Designed and produced for use in extreme sports, this watch features a broad steel and titanium case guaranteed water-resistant to 120 metres.
MONTECRISTO PROFESSIONAL is equipped with either an elaborate mechanical self-winding movementor a quartz-driven chronograph movement.
The assembly, adjustment and precision testing of this watch are performed in the LOCMAN laboratories by the technicians and master-watchmakers of the S.I.O. 
The steel unidirectional bezel for measuring dive times is notched to ensure a better grip and facilitate adjustment even under water.
Fitted with a folding clasp, the strap features a device facilitating length adjustment, which avoids the owner needing to have this operation done by a watchmaker or by the company itself.
