Although the portfolio includes two more highly popular aquatically-inclined collections, Sea-Dweller has become quite a cornerstone model for Rolex. Its balanced design sensibility and marine prowess are much celebrated and have led to the emergence of a completely new line of watches - the Deepsea.

This reference 126603 was introduced in 2019 and stands out from its predecessor with its refreshing two-tone look. The case is still 43mm wide and water resistant up to a whopping 1220m, but it's now rendered in stainless steel and yellow gold. Other familiar details include the black unidirectional Cerachrom bezel and a discreet helium escape valve at nine.

At Second Movement, the pre-owned division of Ethos Watches, we adhere to a rigorous verification process where expert watchmakers carefully inspect every watch to certify its authenticity, ensuring it is not counterfeit. We also go to the maximum extent possible to ensure that the timepiece is not a stolen property and that all duties are paid. However, in the absence of any central database, a 100% verification is unlikely for any pre-owned entity in India. Nevertheless, we can still provide a provenance guarantee for watches purchased from Ethos.
