Before the invention of diving watches, what did the divers use? Today, we are just starting from the 1950 s and let's review the history of diving watches.

In the early 1950 s, Rolex and Blancpain launched their first professional diving watches, but they just created the model of modern diving watches and reformed the traditional rotating watch bezel, the first piece of diving watch in the history were not invented by them. Let's go back to the second world war, the navy at that time, especially Italy frogloks proved the importance of underwater warfare and the necessity of salvage, and therefore the demand of water-resistant is greatly increased. All kinds of water-resistant swiss replica watches appeared on the market in the 1940 s, at that time, in order to increase the water proofing property, water-resistant watches were equipped with more than one metal crown.

In the early 1930 s, Panerai began to offer all kinds of instruments for the Italian navy and worked together with the Rolex to provide them with the first batch of watches that were specially made for divers. Over the same period, Omega introduced a rectangular Marine watch, the double-layer watch case by sliding connection and unique locking devices constituted a airtight waterproof space, thus make the wrist watch waterproof deeper than 100 meters (at least it is true in theory). Because of these features, this watch was worn by the diving pioneer William Beebe and Yves Le Prieu. But we still have to go back earlier, in the 1920 s, the wrist watch manufacturers have started to introduce various types of water-resistant watches. Rolex at the same time had launched its most famous oyster type watch, the water-resistant watch accompanied with famous Natalie miyuki Disir across the English channel, without any damage after socked in the sea water for 15 hours and a quarter of an hour to be famous since then.
