Description

Introduced in 2017 to commemorate the 50th anniversary of the Sea-Dweller, the Rolex reference 126600 represents a significant evolution of the professional dive watch lineage. Its 43 mm Oystersteel case enhances wrist presence while preserving the robust engineering expected of the model. The black dial features the historic red “Sea-Dweller” signature — a nod to early prototypes — alongside Chromalight hour markers and hands for optimal underwater legibility.

For the first time in the Sea-Dweller family, Rolex fitted a Cyclops lens over the date at 3 o’clock, paired with a domed sapphire crystal engineered to withstand extreme pressure. Inside, the automatic caliber 3235 provides improved efficiency, precision, and a 70-hour power reserve. The unidirectional ceramic bezel with Cerachrom insert ensures durability and clarity, while the Oyster bracelet with Oysterlock clasp, Glidelock micro-adjustment, and Fliplock extension system guarantees a secure and adaptable fit over a wetsuit. The 126600 balances technical capability with modern proportions, making it one of the most versatile contemporary professional Rolex references.
