Watch is sold as-is. Other than it looking new and unused, running about 10 seconds fast per day, case dimension about 32mm x 40mm x 10mm, and fitting a wrist up to 6.5", I do not know the specs of this watch. What you see is what you get (Omega Watch and Red Omega Box shown). To change the date, you would have to continuously wind the crown until the correct date is shown. (Caliber 1011)? Any Constellation collectors would know more than me regarding this sharp and clean watch (the only blemish I see is the hairline scuff on the back--you can see it too). Watch will be sold for $230 obo, paypal preferred, shipped CONUS with tracking.

Sold and purchased many watches online here, so I do have great references if needed.

Kind regards,
Louis
