Omega Constellation Chronometer – Calibre 561 – Octagonal Crown

A beautiful vintage Omega Constellation Chronometer, featuring the elegant design language and technical quality that made the Constellation one of Omega's most respected collections.

The silver dial features a clean, understated layout with applied faceted baton hour markers and elegant hands. A contrasting outer chapter ring frames the dial, creating a subtle two-tone appearance that adds depth and sophistication. The applied Omega logo and Constellation signature complete the classic design.

The stainless steel case features beautifully shaped lugs and is complemented by the distinctive octagonal Omega crown, an attractive period detail that enthusiasts of vintage Constellations will appreciate.

Inside beats the renowned Omega calibre 561, an automatic chronometer-certified movement with 24 jewels. Introduced in 1959, this movement belongs to Omega's celebrated 550 series and is appreciated for its robust construction, precision and traditional mechanical architecture. The date complication adds everyday practicality without compromising the balanced appearance of the watch.

The watch is fitted with a brown leather strap and retains its original Omega pin buckle, a particularly nice detail that completes the vintage presentation.

A timeless vintage Constellation combining chronometer-grade watchmaking, elegant proportions and the unmistakable character of Omega's golden era.
