I have been reading list and studying the model / serial number breakdown. I have a F1 that is WAH1110 JV2503. Can you break down the meaning of the JV2503 and what type of band this comes with? I really thank you for the help in due of me being new here.

 

If "JV2503" is on the caseback, right below the WAH1110, it's the serial number for your watch.

The bracelet reference might be BA0850 or BA0858, and the rubber strap would be FT6024.
