The now-discontinued reference 116660 paved the way for the new 126660 variation in the Deepsea collection, distinct from the Sea-Dweller line. The decision to separate Deepsea from Sea-Dweller came to be in 2023. This previous generation model although no longer in production since 2018, made an indelible mark on the watch enthusiasts who missed their chance to secure this timepiece. Limited pieces of this iteration make rounds in the pre-owned market.

This reference 116660 serves well as a diver's watch thanks to an assemblage of technical intricacies such as the multilayered 44 mm case, rendered in corrosion-resistant Oystersteel. While on the front, the case is protected by a substantially-thick sapphire crystal; the titanium caseback comes with fluted edges secured by screws that can be opened only by a special tool owned by Rolex watchmakers. The patented Ring Lock system, unidirectional Cerachrom bezel, and the helium escape valve at nine o'clock reinforce this reference's functional supremacy.

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.
