The watch Purchased directly from the original owner, this elegant Omega De Ville is a distinctive and uncommon hand-wound example that has just been professionally serviced. The refined hexagonal case, measuring 25 mm, gives the watch a unique architectural presence and pairs beautifully with the grey linen dial.
The watch has been kept in excellent condition, showing only very minor signs of wear consistent with careful use. The case and original hesalite crystal are particularly clean, while the caseback displays light marks from previous servicing. The watch is fitted with a 14 mm Hirsch leather strap with crocodile print, complementing its vintage character.
All components are original. The hesalite crystal is correctly signed with the Omega logo, as is the crown.
The watch has been fully serviced by a professional watchmaker in January 2026. The service included complete disassembly, cleaning, lubrication, and reassembly.
It is offered as a full set, including the original box and papers.
Details The Omega Caliber 620 is a manual-winding mechanical movement introduced in the mid-1960s as part of Omega’s 600-series. It was developed primarily for smaller and slimmer dress watches and reflects Omega’s focus at the time on reliable, compact hand-wound calibers.
The movement runs at a frequency of 19,800 vibrations per hour (2.75 Hz) and contains 17 jewels. It has a diameter of approximately 23.7 mm and offers a power reserve of around 42 hours. The Caliber 620 is equipped with shock protection and is known for its robust and straightforward construction, making it relatively easy to service.
Produced during the late 1960s and early 1970s, the Caliber 620 represents a period just before quartz technology became dominant in the watch industry. Today, it is regarded as a solid and dependable vintage Omega movement typical of the brand’s mechanical production of that era.
