I am looking for a new bracelet for a watch. In pictures for the 1161.172 bracelet the clasps are stamped with the omega logo and the strap number, some of them have the 1161 and the number 32 stamped on them and some of them have 1161 and the number 11 stamped on them. Does the variation in the number 11 and 32 have any significance?

Appologies if this is a stupid question, I am learning stuff all the time and appreciate any help.
