Omega Seamaster 600 White Dial (1966) – a rare piece of Omega history

Some watches bear their rarity in their name. The Omega Seamaster 600 is one of the less frequently offered vintage models of the brand, and this 1966 example embodies exactly what Omega stood for in that era: robust craftsmanship, clear design, and a character rarely found today. Freshly serviced in August 2026, this Seamaster 600 is a truly remarkable piece for any vintage collection.

Historical, rare, and lovingly preserved

This Seamaster 600 impresses with its original Omega crystal – a detail that is not to be taken for granted in a watch over 55 years old and further emphasizes its authentic character. The case and dial are in very good condition, as is the crystal. Before sale, the case was highly polished and the original acrylic crystal professionally polished, so the watch now presents a well-maintained yet authentic appearance. The look is complemented by a new leather strap in like-new condition. The case back shows age-appropriate but charming traces of its long history.

Freshly serviced – a hand-wound movement with character

In August 2026, the watch was fully overhauled by our watchmaker: the movement was cleaned, oiled, and regulated, and the entire watch professionally inspected. Inside, the Omega Calibre 601 ticks – a robust hand-wound movement from the 1960s. The measurements after service show a very well-functioning movement:

• Power reserve (manufacturer specification): 48 hours
• Accuracy: +5 seconds/day
• Amplitude: 255°
• Beat Error: 1.0 ms

A low deviation of only +5 seconds per day is an excellent value for a hand-wound movement over 55 years old and shows how carefully this caliber has been maintained and regulated.
