Omega Constellation 168.017 (C-Shape): Vintage Reference Guide

January 8, 2026 Joshua Grillet

The Omega Constellation 168.017 is one of the most distinctive vintage Omega dress watches: a late-1960s chronometer housed in the rare "C-Shape" case (a cushion-case variation), powered by the Omega caliber 564 with quick-set date. This reference sits at the crossroads of Omega's chronometer-certified Constellation legacy and the bold case design language of the late 1960s. Here's the complete reference guide to the Omega 168.017 — dial variants (including the rare finely striated dial), movement, how to spot an original, and current market value.

The Constellation range was launched by Omega in 1952. The movements are chronometer-certified and the case backs are engraved with the image of the Geneva Observatory and eight stars.

These watches are elegant, precise, and beautifully finished.

The model we are interested in here is reference 168.017 SP and dates from the late 1960s. The case shape is known as “C Shape” on this reference, a variation on the cushion case. A brushed bezel and chamfers are also featured, creating a beautiful play of light across the whole piece. The movement is an Omega 564, chronometer with a quick date function.
