This is a used Ulysse Nardin Maxi Marine Chronometer Blue Rubber Watch Strap. 

This is a OEM strap that was recently taken off of a Ulysse Nardin watch.

This strap will fit 22mm lugs and is 4 pieces that are designed to be used with a Nardin Maxi Marine Deployment clasp and metal bars. 

Included are 2 smaller pieces both marked "500" and 2 larger pieces marked "103". 

This strap being rubber was cut down and would fit a 7.5" wrist when on a deployment clasp in the middle, so you could probably cut it down further or use it as it is cut for wrists 7.25" to 7.75". 

The strap is in used condition. It has no rips/tears, but there are light scratches and other signs of wear on it from use.
