Omega Constellation Chronometer C-Shape Day-Date (1970) – Iconic design meets genuine white gold

The “C-Shape” case is one of the most distinctive designs in the entire history of the Omega Constellation – named after the striking, tapered case shape, which remains one of the brand’s most elegant vintage designs to this day. This 1970 Constellation combines this iconic case with a genuine 18k white gold bezel in mint condition – a combination rarely found on the market in this quality.

Iconic case, high-quality bezel

The 18k white gold bezel is in mint condition and is the clear highlight of this Constellation. The grey day-date dial is in very good condition and harmonizes beautifully with the professionally refinished steel case. Before sale, the case was high-polish finished, the watch was fitted with a new crystal that presents as new, and it was paired with a new leather strap – the strap itself is in like-new condition. The case back is in good, age-appropriate condition.

Freshly serviced – a chronometer-certified automatic movement

In September 2026, the watch was fully overhauled by our watchmaker: the movement was cleaned, oiled, and regulated to -3 seconds per day, and the entire watch was professionally inspected. Inside beats the Omega Caliber 751 – an automatic movement certified as a chronometer. The post-service measurements confirm its very good condition:

• Power reserve (manufacturer spec): 50 hours
• Rate deviation: -3 seconds/day
• Amplitude: 260°
• Beat error: 0.2 ms

These values indicate a smooth and precise movement – fully in line with the chronometer standards for which the Constellation became famous.
