Introduced in 1982 after a long line of chronometers that made Omega a household name, the "Constellation Manhattan" is one of the few eighties designs to stand the test of time.  Originally designed by Carol Didisheim and patented in 1985, the barel shaped case features "not one sharp line on the enire case and bracelet--even the case back edges are rounded off."*
 
The four distinctive gold claws identify its strikingly elegant and timeless look, further pressing the sapphire crystal against the case, assuring the watch's water resistance.  Form and Function unite to create the ultimate in design achievement.The extra flat quartz movement adds to the boldness in the art of watch design--for the connoisseur fascinated by elegant good looks. 
 
The example is the "Full 18k gold bar" embellishing the stainless steel bracelet with hidden clasp, 18k bezel and crown and beautifully textured face. 
 
Condition:
Recently serviced by an Omega certified, WOSTEP watchmaker, including new battery, Genuine Omega Case gaskets and Crown.  The watch fits my 7 3/8 inch wrist comfortably,  and measures 7 1/2 inches.  Additional links are available from Omega. The dial is exceptional and crisp, the bezel shows a very small blemish at 9:00, and the one gold bar near the clasp is slightly indented, but does not affect functionality.
