Omega Chronograph Cal. 321 Jumbo 1966

Ask any true watch collector about the greatest movements ever designed and there is a strong chance they will affectionately mention the Lemania Caliber 321 movement designed by Albert Piguet. Utilized in the original Omega Speedmaster during the American Space Program missions in the 1950s and 1960s, this workhorse movement has become a thing of legend, and deservedly so.

Our particular watch comes in a 37 mm stainless steel jumbo case and beautiful designed lugs. Accents like the awesome yellow gold hands and hour markers complete the classy look of this piece. 

Our chronograph is bearing the caliber 321, making it a dressier option for the collector who desires a caliber 321 but doesn't want a Speedy.
