Omega. An unusual and special Omega reference CK 2077 chronograph with multicolored central scales and a beautiful aged patina dial Model: Chronograph Material: stainless steel Reference N°: CK 2077 Year: 1940's Case N°: 10123408 Caliber: 33.3 Bracelet: leather strap Dimensions: 38 The present Omega CK 2077 chronograph is an astonishing object and a very rare wristwatch for its unusual dial layout combining pulsometer and tachymeter scales with the attractive two-done color scheme and very good overall condition. When reference CK 2077 was first launched in 1937, it was Omega’s first water-resistant chronograph and can also be considered a turning point in the firm’s history equipped with the famous caliber 33.3. This manual winding movement is an icon amongst collectors: it was firstly introduced as a mono pusher in 1933 but was later readapted and used for two pushers chronographs given birth to the first water-resistant watch. As we have seen, the present timepiece is a wonderful, early example of these water-resistant chronographs with its oversize, for that time, stainless steel case measuring 38.5 mm and two round pushers in contrast with the classic olive or square buttons. The screw back in still very fresh with clear engravings “waterproof model+depose”. The silver dial with wonderfully aged patina also offers the unusual Roman numerals in addition to the copper-colored tachymetre scale, inner gilt and copper-colored spiral telemeter scale. The exciting feeling from seeing and wearing the present chronograph is undeniable, and makes it an important and special watch for a discerning collector. € 30000 - 60000
