With its black dial, satin-finished steel case, and metallic wristband, this model embodies the quintessence of the Deep Sea 300 diver’s watch. The Crown Protection SystemTM provides a secure watertight seal. Its wristband can only be fastened if the crown at 6 o’clock is fully screwed down. Its ECSTM system ensures optimal rinsing after a dive, enabling the removal of impurities and salt crystals lodged between the unidirectional rotating bezel fitted with a ceramic insert and the case. Its hands and date are driven by a reliable Swiss Made self-winding caliber.
