I am on a mission in getting the bar bracelet for my Speedmaster TV dial 176.0014. I found other type of Speedmasters are using the similar bar bracelet, however the number on the clasps are different. Normally it is written in the format of xxxx/xxx as and example 2104/212. I have attached a couple of pics showing that. Both are bar bracelet type but has different number on the clasps. Can anyone enlighten me with the meaning of the numbers on the clasp? Does that mean that they are interchangeable between each other? Thank you in advance for all the info and inputs given. Have a nice day all! Josh
