102406 - Launched in 1967, the Sea-Dweller was the first Rolex divers' watch with a date display. A useful feature for a watch designed for professional saturation divers, who typically "dwell" for days, weeks or even months in pressurized habitats during their missions. Yet the signature Cyclops magnifying lens on Rolex calendar watches could not be integrated on the original models as it would weaken the Plexiglas crystal under high pressure and compromize the watch's waterproofness. On the anniversary edition of the Sea-Dweller released in 2017, Rolex engineers managed to solve this technical issue and add a Cyclops lens for the first time to this iconic model.
