The watch has an attractive blue dial with applied silver-tone hour markers, black hands, a white outer timing scale and a framed date window positioned at 3 o’clock. The combination of the blue dial and brushed stainless steel case gives the watch a characteristic late-1960s sports-watch appearance. It is powered by the Omega Calibre 920, a manual-winding mechanical chronograph movement with a date function. The Chronostop system uses a single pusher: pressing the button starts the chronograph hand, pressing and holding it stops the hand for reading, and releasing the button resets it to zero. The dial is in clean and attractive vintage condition. The stainless steel case and bracelet show scratches, marks and signs of previous use consistent with the age of the watch. The acrylic crystal may also show light scratches and age-related marks. Please examine all photographs carefully, as they form an important part of the description. The watch is fitted with a stainless steel bracelet that complements its sporty vintage design. The manual-winding movement is currently working, including the date and Chronostop functions. However, as with all vintage watches, long-term accuracy, power reserve and water resistance are not guaranteed unless otherwise recently serviced. The service history is unknown. A distinctive and collectible vintage Omega Chronostop, suitable for collectors and enthusiasts of unusual Swiss mechanical chronographs. Shipping: The watch will be carefully packed and shipped with a tracking number via international courier. Customs & Duties: Any customs duties, import taxes or other charges that may arise in the buyer’s country are the responsibility of the buyer.
