The Submariner was introduced by Rolex in 1954. The watch comes only on an Oyster bracelet and has a 40mm case. The steel model is only available with a black dial. It has the common single direction rotating bezel with minute markers for the first 15 minutes. The original models until 1958 are often considered "James Bond" models and have some easily recognizable difference. Primarily, they had a smaller crown, no crown guard, and the bezel only had minute markers every 5 minutes. In the late 70s the model 16800 was introduced. It sported the new sapphire crystal and quick-set function. In 1989, the current 16610 was introduced with a improved movement and a more secure bezel. The Rolex Watch Company, for a period of 35 years, from 1970 - 2004, presented a 'Submariner' watch to the fastest channel swimmer of the year in addition to supplying each Observer with a totally accurate timepiece for the purpose of timing the swim. The Submariner is one the most popular models and comes in 4 styles, $5450 for steel (no date), $6000 for steel (with date), $9300 for 18k & steel, and $27,250 for the all gold model.
