Rolex is introducing an Oyster Perpetual Sea-Dweller in a yellow Rolesor version, combining Oystersteel and 18ct yellow gold. This new watch brings 18ct yellow gold to the Sea-Dweller range for the first time. On its black dial, the name “Sea-Dweller” is inscribed in a yellow hue, echoing the colour of the 18ct yellow gold off the unidirectional rotatable bezel, which is fitted with a 60-minute graduated Cerachrom insert in black ceramic. The Oyster Perpetual Sea-Dweller is equipped with the new-generation calibre 3235. This movement incorporates the Chronergy escapement, developed and patented by Rolex, and offers a power reserve of approximately 70 hours.
