Rolex 126600 (New with box and papers) — USD 18,975 on eBay

The Rolex Sea-Dweller reference 126600, introduced in 2017, marked a significant update to the Sea-Dweller line, commemorating the model's 50th anniversary. This reference is notable for its increased case size and the reintroduction of the single red line of text on the dial, a nod to early Sea-Dweller models. It bridges the gap between the traditional Sea-Dweller and the larger Deepsea models, offering enhanced presence on the wrist while maintaining the core design language of the professional dive watch series. This model features a 43 mm Oystersteel case, equipped with a helium escape valve, and is fitted with a unidirectional rotating bezel with a black Cerachrom insert. The watch is powered by the Rolex Caliber 3235, an automatic movement known for its precision and a power reserve of approximately 70 hours. A sapphire crystal protects the black dial, which includes a date complication at 3 o'clock, a departure from previous Sea-Dweller models that lacked the Cyclops lens. The 126600 appeals to collectors seeking a modern Sea-Dweller with historical design cues. Its larger size and the distinctive red text differentiate it within the contemporary Rolex sports watch lineup. While it maintains the robust engineering expected of the Sea-Dweller, its specific aesthetic details and technical upgrades make it a distinct offering for those interested in the evolution of Rolex's professional dive watches.
