Omega Marine - First ever divers watch 1932 Watch designer was Louis Alex, made by Frederic Baumgartner. What made the Marine so unique and so capable was this two-part case, which had its top and bottom pieces connected to the straps, while a large clasp locked them securely on the case back. Furthermore, the Marine was the first watch to have a synthetic sapphire front, clearly an important step forwards in terms of reliability compared to any other material used at the time. The "package" was completed by a seal leather strap which, by Omega's claims, were extremely resistant to salt water. The concept was ready so it was time to put it to its paces: Omega, likely "inspired" by Rolex's marketing successes, set out to prove the special capabilities of their watch by testing through a series of challenges, challenges which were of previously unimaginable difficulty. In 1936 a couple of Marine watches spent minutes in hot water (of 85 degree Celsius) and were then quickly submerged to a depth of 70 meters in the 5 degree Celsius cold waters of Lake Geneva for thirty minutes. When they were taken out, all pieces (two complete watches and a case with no movement inside) were functioning perfectly, showing no traces of water inside.
