This is a massive 1973 41.5mmx49mm. OMEGA SEAMASTER automatic chronograph essentially displaying pristine (new old stock) condition with the original full-length bracelet. The blue dial and original handset looks fantastic. The caliber 1040 movement with 24 hour feature was recently cleaned. The chronograph and timekeeping are excellent. The OMEGA case has the original OMEGA brushed finish-WOW! Where else will you find such a pristine example of a desirable vintage OMEGA chronograph? This OMEGA CHRONOGRAPH is blood AMAZING!
