The 1940s were undoubtedly the most difficult years for the Swiss watchmaking industry. At the end of World War II, several companies were extremely dangerous. Years of devastating wars throughout Europe have kept watch production at record levels. For example, the export volume of Omega dropped from 23.9 million watches in 1937 to 11.8 million in 1944, but if Omega did not receive large orders for military watches, the situation could be even worse. After World War II, sales of Omega watches quickly caught up with pre-war figures, reaching 18 million by the end of 1945. Celebrating the company’s centenary in 1948, Omega management decided to invest 20 million Swiss francs to build a new plant to increase its production capacity and began to shift its focus to the booming ‘professional’ market. Based on the experience of making waterproof watches for the British Army during World War II, Omega wanted to use rubber to produce waterproof rings instead of the lead rings, shellac, and grease that were common at the time. In the end, a series named ‘Seamaster’ was born. At that time, Ref. CK 2518 small three-pin Chronometer observatory version and Ref. CK 2577 large three-pin version were released, and the waterproof depth reached 60 meters. During a tour of Venice, Omega designer JEAN-PIERRE BORLE discovered the seahorse decoration on the side of the gondola ship, and made this pattern into the logo of the seahorse series. Because of its waterproof design in the early days of the hippocampus series, the target customers were people who were inclined to sports, rural, outdoor, so it won the reputation of ‘professional’. In 1957, Omega launched Speedmaster and Railmaster, two special watches also known as ‘professional’, so the hippocampus logo is not limited to the Seamaster hippocampus series. In 2012, the London Olympics was about to be held. In order to commemorate the birth of the Seamaster series, it actually originated from the experience of making waterproof watches for the British army during World War II. Therefore, Omega launched a replica of the hippocamp Ref. CK 2518, using the Ref.2202 movement. , And certified by the COSC Observatory, limited to 1948 pieces on sale.
