1968 Omega Constellation Ultra-Thin Starburst Opaline Silver 167.021

The 167.021 represents a raising of the bar from Omega's already high standards during the "golden era" of the 50's and 60's.  By the early to mid-60's Omega had reached a very good standard of water resistance and durability as well as accuracy in their watches.  The Calibre 55x series had both improved the automatic 50x series and made it thinner, but the ultra-thin Calibre 712 Chronometer went even further.

The Calibre 712 was, and as of early 2023 still is, the thinnest automatic chronometer movement ever made by Omega.
