The Rolex Submariner 16610LV was built to commemorate the 50th anniversary of the Submariner's introduction, which was introduced in 1953. The Submariner 16610LV is unique for its green bezel and black dial, as well as being the first Sub to feature a modern maxi dial, with larger hour makers on a glossy dial. The 40mm case and oyster bracelet are constructed of 904l steel and have a brushed finish. The Submariner LV can hold its own under water as well, thanks to lumed hour markers and hands, a chronometer certified movement, and a depth rating of 1,000ft/300m. The automatic movement inside was developed and built in-house by Rolex.
