Omega Constellation 2000 Ref.355.0814 – Vintage Men's Watch Black Dial 1970s | Cal. 711 Automatic Ultra-Thin

Eight millimetres of automatic ambition.

The Constellation 2000 ref. 355.0814 is one of Omega's most quietly radical designs — a full-rotor automatic dressed in a case so thin it reads as quartz at first glance. That 8 mm profile is the work of the Calibre 711, a movement designed for exclusive use by Omega, running at 19,800 vph with a 42-hour power reserve. Thinness this extreme in an automatic was extraordinary in the 1970s, and it remains impressive today.

The square stainless steel case — 31.5 mm wide, 37 mm tall — integrates seamlessly into the bracelet, the two becoming a single object on the wrist. Dauphine hands sweep over the matte black dial, framed by a gold-bordered bezel. Brushed and polished surfaces work in contrast across the case and tapering bracelet links. The hidden deployant clasp keeps the profile clean from every angle.

Just serviced and ready to wear. Dial in excellent condition. Comes complete with original box, hangtag, and 3 extra links.
