Rolex Sea-Dweller 50th Anniversary

About this reference

The Rolex Sea-Dweller reference 126600 entered production in 2017 to commemorate the model's 50th anniversary and remains in the current catalog. This reference introduced a 43mm stainless steel case, a departure from the traditional 40mm size, and integrated the caliber 3235 movement with a 70-hour power reserve. Collectors prioritize this model for its "Single Red" dial, featuring the Sea-Dweller name in red text as a tribute to the original 1967 prototype. It was also the first Sea-Dweller to include a cyclops magnification lens over the date window, a controversial design shift for the line. On the secondary market, prices typically range between $13,000 and $16,000 depending on condition and documentation. Early 2017 production units are sometimes distinguished by collectors as "Mark 1" dials, which lack the small Rolex crown emblem at the six o'clock position introduced in later iterations.
