Light scratches throughout consistent with desk diving. The watch has been modified with a genuine sapphire exhibition caseback from a 3572.50, installed by a watchmaker. This includes the correct movement spacer ring and extra gasket. The original steel caseback/dust cover/movement spacer is not included, though those can easily be found on eBay if you want to restore it. If done, you could easily sell the sapphire caseback and spacer parts for $800+ on eBay. Note that a little bit of the black enamel has worn off the inscription. The watch was last serviced by Omega in 2016 and still keeps COSC time (even though it's not COSC-ceritifed) when worn. Unfortunately, the service paper and original leatherette box were thrown away because they were drenched/damaged by flood waters during Hurricane Harvey in 2017 in storage at a separate location. Original warranty and pictogram cards are included.
