Rolex Submariner 40 mm 116610LN Steel Black Rolex Submariner 40 mm 116610LN Steel Black

The Rolex Submariner is, without question, the most recognized and revered dive watch in horological history. Introduced in the early 1950s, the Submariner pioneered the genre of the luxury sports watch, blending professional underwater functionality with timeless aesthetic appeal. The 116610LN — the black-dial configuration — represents the purest, most classic expression of the Submariner lineup, pairing a black dial with a matching black bezel for an understated yet commanding presence on the wrist.

At 40mm in diameter, the Submariner 116610LN occupies the sweet spot that made the model a universal classic. The case is crafted in Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional resistance to corrosion and its polished finish. The Oyster case architecture — featuring Rolex's signature screw-down crown — delivers a water resistance rating of 300 metres (1,000 feet), making it fully capable as a professional dive instrument while remaining equally at home in a boardroom or at a dinner table.

The 116610LN pairs a 40mm Submariner Date case with a black Cerachrom ceramic bezel insert. The unidirectional bezel has a 60-minute scale and a luminous marker at zero. The black dial has luminous hour markers and hands for legibility in low light.

Powering the 116610LN is a Rolex-manufactured automatic movement, the self-winding calibre at the heart of this reference, regulated to Superlative Chronometer standards and certified by both Rolex and COSC for precision performance. The movement is protected within the hermetically sealed Oyster case, ensuring long-term reliability whether the watch is worn daily or stored as a collector's piece. The Oyster bracelet, equipped with the Oysterlock safety clasp and the Glidelock extension system, provides fine incremental adjustment for a secure, comfortable fit over a wetsuit or directly on the wrist.

The 116610LN belongs to the 40mm Submariner Date generation that preceded the 41mm range introduced in 2020.
