Rolex watches have a sturdy case and movement

The Oystersteel instance provides a more robust outlook shielding the watch against intense conditions either due to wind, dust, water or pressure. Dive watch can quickly set their period, together with the knurled edges of the bezel. The watch is further punctuated using the Chromalight zero marker, making it functional even at the darkest corners underwater. At all times, the watch is firmly secure from the wrist, as a result of the patented glidelock of the bracelet.
Equipped with the 3135 calibre movement, the Rolex Submariner comes with a self-winding mechanism entirely developed and manufactured by Rolex. COSC-certified Swiss chronometer, this in-house calibre movement comprises Rolex’s Parachrom hairspring, boasting great resistance to shocks and changes in temperatures. Finally, the unidirectional rotatable bezel allows the diver to monitor the dive-in period and decompression. It is also scratch-proof, therefore unaffected by the high-chlorinated seawater.
