Omega Constellation Chronometer – Automatic Day-Date – Original Brown Spider Dial – 38 × 37 mm

This vintage Omega Constellation pairs a broad, rounded-square stainless steel case with an original brown dial that has developed a distinctive spiderweb patina. Slim silver-tone baton markers and a framed day-date display stand out against the aged dial, while the stepped bezel gives the watch a strong architectural profile. It is fitted with a dark brown leather strap and presented in its original red Omega Constellation box.

Story & Heritage

The observatory on the case back is a fitting detail for a watch whose dial bears the words “Chronometer Officially Certified.” The dial speaks plainly about precision; the reverse gives that idea a visual form, with an observatory dome beneath a field of stars.

What makes this particular Constellation memorable is the contrast between the precise geometry of the steel case and the irregular pattern that time has left on the dial. The fine web is especially visible below the hands, where the brown tones deepen. Against that surface, the silver batons and white calendar discs keep the display easy to read.

The red Constellation box adds a final touch to the presentation. For a collector drawn to shaped steel cases and dials with visible age, this example offers both in a watch with a distinctly individual appearance.
