One of the most newsworthy Rolex introductions from 2017 was surely the new 43 mm diameter Sea-Dweller.
The 2017 Sea-Dweller features the next generation Rolex 3235 caliber automatic, that has a 70-hour power reserve and is a so-called Superlative Chronometer with impressive -2/+2 precision after being cased up.
A new ceramic bezel with numerals and graduations coated in platinum resists scratches. Water-resistance is 1220 meters (4000 feet), along with an escape valve, which is nowhere near the superfluous depth rating of the 44 mm diameter Deep Sea, but it is more than enough for any professional diving needs, and it does so in a smaller 43 mm diameter case. Moreover, at $11,350 it is less than the Deep Sea. (Ref. 126600)
