The 116610LN was the Submariner Date from 2010 to 2020 and marked a clear step on from the 16610. The bezel gained a ceramic Cerachrom insert that does not fade and hardly scratches; the case became more substantial, with broader lugs and larger crown guards, and the dial received larger indices and broader hands.
The bracelet gained solid end links and the Glidelock clasp, which adjusts the length in small steps without tools. Inside works calibre 3135, a proven movement with a power reserve of about 48 hours. Case and bracelet are made of 904L steel, which Rolex has called Oystersteel since 2018; the watch measures 40 mm and is water-resistant to 300 metres. In 2020 it was followed by the 126610LN, with calibre 3235 and a 41 mm case.
As a pre-owned watch the 116610LN remains in demand, among others with buyers who prefer the more substantial case to the slimmer lines of its successor. In our assessment we look at the condition of the bezel insert, the luminous material, the clasp and any polishing marks, and at the completeness of the set. The guarantee card states the serial number and purchase date and must match the watch.
