New Old Stock G-S brand acrylic watch replacement crystal for an Omega Speedmaster earlier reference 1960s/70s model. Very economical option compared to trying to source an original Omega crystal. This is a non-Omega replacement part for Speedmaster watches requiring a 34.2mm diameter crystal part. Does not come with the metal reflector ring; you just re-use the one from the old crystal. Does not have the Omega symbol etched into the plastic. G-S brand part PA474-50 sent in its original packaging shown. The packaging diagram serves as an accurate illustration of the shape and type of this crystal. 

Measure your watch case accurately with digital calipers to determine the size you need or take it into a watchmaker first. There are no returns for wrong size ordered.
