2017 Rolex Sea-Dweller 126600 MK1 Dial 43mm – Box & Papers – Excellent Condition

2017 Rolex Sea-Dweller 126600 MK1 Dial 43mm – Box & Papers – Excellent Condition

Offered here is an exceptional 2017 Rolex Sea-Dweller Reference 126600 featuring the desirable early-production MK1 dial, presented in excellent condition and accompanied by its original Rolex box and papers.

The reference 126600 was introduced in 2017 to celebrate the 50th anniversary of the Rolex Sea-Dweller, making early examples from this production period particularly interesting to collectors.

What makes this example especially noteworthy is its MK1 dial. The early MK1 configuration is distinguished from later-production 126600 dials by subtle dial details, most notably the absence of the small Rolex coronet between the “SWISS MADE” text at 6 o’clock. Later MK2 examples incorporated the coronet.

Combined with its 2017 production year, original box and papers, excellent condition, and MK1 dial, this Sea-Dweller offers additional collector appeal beyond that of a standard pre-owned 126600.

Iconic Red Sea-Dweller Dial

The black dial features the signature red “SEA-DWELLER” lettering, a design detail that pays tribute to early vintage Sea-Dweller references and gives the 126600 its distinctive identity.

Large luminous hour markers and hands provide outstanding visibility, while the date window at 3 o’clock is paired with Rolex’s signature Cyclops magnification lens.

Surrounding the dial is a black Cerachrom ceramic unidirectional rotating bezel, providing the unmistakable appearance of a modern Rolex professional dive watch.

43mm Professional Oyster Case

The Sea-Dweller 126600 features a substantial 43mm Oystersteel case, providing noticeably greater wrist presence than the traditional Submariner while maintaining classic Rolex proportions.

Engineered for professional diving, the Sea-Dweller incorporates Rolex’s helium escape valve and is rated for water resistance to an impressive 1,220 meters / 4,000 feet.

The watch is completed by the iconic Oyster bracelet with Oysterlock safety clasp, delivering a secure and substantial feel on the wrist.

Rolex Calibre 3235

Powering the Sea-Dweller is the Rolex Calibre 3235 automatic movement, offering exceptional reliability, precision and approximately 70 hours of power reserve.

The movement represents Rolex’s modern generation of mechanical engineering and makes the 126600 equally suitable as a serious everyday luxury watch or an important addition to a Rolex collection.
