What the 1,220-metre rating and helium valve mean
Rolex lists the 126600’s water resistance as 1,220 metres (4,000 feet) and equips it with a helium escape valve. These are design specifications for a professional dive watch; the rating is not a recommendation to expose a watch to that depth casually. For care, operation and any questions about the watch’s condition, consult an Official Rolex Jeweler.
The bezel is unidirectional and graduated for 60 minutes, with a black ceramic Cerachrom insert. Its scale supports elapsed-time tracking, while the Triplock screw-down crown and screw-down case back form part of the Oyster case construction.
Calibre 3235, date and daily precision
The watch uses Rolex’s self-winding calibre 3235, with an approximately 70-hour power reserve. Rolex specifies precision of −2/+2 seconds per day after casing. The date appears beneath a Cyclops lens on the scratch-resistant sapphire crystal.

How the 126600 fits the Sea-Dweller history
Rolex says the Sea-Dweller was updated in 2017 for its 50th anniversary. The update brought the larger 43 mm case, calibre 3235 and Cyclops date lens, according to the brand’s 2017 history page. The red “Sea-Dweller” name on the dial is a reference to the first model, Rolex says.

Rolex directs buyers to Official Rolex Jewelers and says their skills, technical knowledge and special equipment help guarantee the authenticity of parts. A retailer page also says the official retailer completes and dates the guarantee card, which certifies authenticity. When considering a purchase, verify the seller’s official status and the accompanying paperwork; these details alone should not be treated as a universal authentication checklist for a pre-owned watch.

Who should consider the Sea-Dweller 126600?
The 126600 is most relevant to someone who wants a substantial 43 mm steel dive watch with a date, a high stated water-resistance rating and Rolex’s professional-watch features. Its specifications do not, by themselves, establish that it is a better choice than a Submariner, Deepsea or another dive watch. Compare case size and fit, water-resistance rating, bezel design, movement, power reserve, date display, bracelet adjustment, price and intended use before choosing between models.
