Sea-Dweller Deepsea Challenge

In Context

At 50 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. At 23 mm it is very tall, and sits high off the wrist. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 11000 m is a professional diving rating, far past any demand a wrist is likely to make of it.

The movement winds itself from the motion of your wrist. 70 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

126067-0001 is one of 2 executions of the 126067 base reference. Underneath they are the same watch; what separates this one is a black matte dial and a titanium, ceramic case.

The 3230 is the no-date version of Rolex's current three-hand movement, introduced in 2020 for the Oyster Perpetual, the Submariner and the Air-King. It powers 37 watches in this library. It is the [3235](/calibers/rolex-3235) without its calendar: the Chronergy escapement, the blue Parachrom hairspring, Paraflex shock absorbers, a 70-hour reserve from a redesigned barrel, 31 jewels and a beat of 28,800 vph at 28.5 mm across, tested after casing to the Superlative Chronometer standard of two seconds a day. The [3135-to-3235 piece](/blog/rolex-3135-to-3235-what-changed) explains the generation. In the library it powers 16 references of the 41 mm [Oyster Perpetual](/brands/rolex/oyster-perpetual), 14 of the [Oyster Perpetual 36](/brands/rolex/oyster-perpetual-36) with its coloured dials, 3 Explorers, 2 [Sea-Dweller](/brands/rolex/sea-dweller) Deepsea Challenges at 50 mm, one no-date [Submariner](/brands/rolex/submariner) and one Air-King. The 41 mm case accounts for 17 references and the 36 mm for 16. The [3130](/calibers/rolex-3130) is the 48-hour no-date movement it replaced, and the [2232](/calibers/rolex-2232) its counterpart in the 28 mm to 34 mm Oyster Perpetuals.

36 other watches in the library run the Rolex 3230.
