Pierre Nicol watches were released in the late 80s early 90s. They are affordable high quality pieces you don't see all the time. These Geometric style ones are even more rare to find. 

This Sapphire blue Pierre Nicol is in good condition.

The dial is clean with no dust build up.

The Crystal isn't foggy and doesn't haven't any scratches

Gold plating on the case is a little lighter on one side then the other but no discoloration.

The band went too long with out conditioning so unfortunately while it may last just once or a few more times or 20 more times you will needs new band. There are several areas where the band is dry rotted.

The last 2 pictures are where the band is connected. Not sure how it would be measured for a new one, so I gave both possible measurements.
