The Omega Chronostop collection was launched in 1966 as an alternative to the expense Speedmaster and Seamaster chronograph collections. There were three varieties of the Seamaster Chronostop made between 1966 and 1969, all of them having a rotating inner bezel. This bezel is operated by the crown between 9 and 10 o’clock. This model is known as the “Pilot Chronostop” due to the inner bezel which is numbered 1/13, 2/14, up to 12/24 and can be adjusted to have a second timezone for travelers and airline pilots. This specific watch was made in 1968.

The large 41mm case makes this watch rather. Inside the case beats the Omega cal. 865 movement, a simplified version of the famous Omega 861 chronograph founds in many Speedmasters. Pressing the pusher the first time starts the second hands, pushing it a second time will stop the second hand. When the pusher is released, the second hands resets to zero immediately. Despite being a simplified version of the cal. 861,  the movement was a high end movement. It’s having 17 jewels and a rather high beat rate of 21.600 Bph and was accurately adjusted.

The bracelet is the original 1170 with 625 endlinks, both original to this watch and in superb condition. Both the case and bracelet are absolutely unpolished! The bracelet is currently suitable for a 18-19cm wrist, with 1 cm of extra links inside the clasp and one spare bracelet link.



The watch is in very good condition and fully original. The case is unpolished and therefore shows some signs of wear like little scratches. Both crowns are original and signed with the Omega logo. The chronostop pusher is original and in good condition. The dial is in very good condition. The hands are original and in very good condition. The movement is in very good condition, operates smoothly and runs accurate within 20-30 seconds a day. The movement has been fully serviced and the watch comes with a 1 year warranty.


Omega Watch Co was founded in La Chaux de Fonds in 1948 by Louis Brandt, under the name La Generale watch Co. The company collected watch parts manufactured by craftsmen in the region and assembled then into complete watches. The company started to focus on industrializing the manufacturing of watches and making parts interchangeable. In 1894, the caliber 19 was launched. Soon after, this calibre was named Omega, the letter that stands for perfection in the Greek Alphabet. in 1903, the decision was made to sell al watches produced by the company under the name Omega. 

In 1903 Omega was employing well over 800 employees and producing over 240.000 watches a year, making it the biggest Swiss watch manufacturer of that era. Omega won numerous medals for precision timekeeping in chronometers trials. As a result from these achievements, Omega was appointed official timekeeper for the 1932 Olympics. In 1948 the Seamaster was introduced, followed by the Constellation in 1952, the Speedmaster in 1957 and the De Ville in 1960.
