This is a rare Omega Speedmaster Reduced, model 3513.53. “Reduced” means it is an automatic movement instead of a handwind only movement.

This was only released to the Japanese domestic market, which makes these very hard to find.

There are scratches on the case and bracelet, and a couple small dings on the top of the lower left lug (see pics). The external AR coating is pretty marked up, which is not unusual with a ~20 year old watch. The crystal is sapphire. The watch functions correctly and resets the chrono hands to 0. I have not noticed any issues with the timekeeping, but I am unaware of the service history.

The inner Omega box is in pretty poor condition. Those red faux leather boxes do not hold up well.

It comes with an OEM bracelet. It is currently mounted on a non-OEM leather band, which is included.
