This pre-owned Rolex Sea-Dweller 126600 – widely known as the 'Red' – is among the most desirable modern Rolex sports references. Introduced in 2017 to celebrate the Sea-Dweller's 50th anniversary, the 126600 marked the return of the iconic red 'SEA-DWELLER' text on the dial – a detail absent since the earliest Submariner variants of the 1970s. Powered by the outstanding Calibre 3235 – Rolex's most advanced movement at the time of launch – and rated to a remarkable 1,220 metres / 4,000 feet, this is a professional dive tool that wears equally well as an everyday timepiece.

Presented in good condition, this example comes complete with original box and documentation, offering a genuine opportunity to secure a highly sought-after reference at a considered price relative to retail.

Water Resistance

Rated to 1,220 metres, the Sea-Dweller's water resistance is exceptional. However, gaskets degrade over time regardless of stated depth rating. If you intend to use this watch for diving, have it pressure-tested before first use. The Triplock screw-down crown provides outstanding waterproofing — always ensure it is fully screwed down before exposure to water, and never operate the crown while wet or submerged.

Service Intervals

Rolex recommends servicing every 10 years under normal conditions. The Calibre 3235 is robust and tolerates extended service intervals well. Authorised Rolex service centres charge approximately £800–£1,200 for a full service; independent specialists experienced with Rolex movements can often offer competitive pricing without compromising quality.

Bracelet Care

The Oyster bracelet's Glidelock extension allows fine adjustment of approximately 5mm without tools. Clean the bracelet regularly with a soft brush and mild soapy water — ensuring the crown is fully screwed down first. The brushed and polished link finishing can be professionally refinished if significant wear develops over time.

The 43mm case suits wrist circumferences from approximately 16cm to 21cm (6.3 to 8.3 inches). The integrated Oyster bracelet with Glidelock extension allows fine adjustment without tools, making it easy to perfect the fit for seasonal changes or different wear situations. Additional link adjustment — to add or remove links — requires a professional watchmaker to avoid damage to the precision-fitted screw links.
