It is for GMT.
What is GMT? GMT is an absolute time reference & doesn't change with the seasons

Thanks for contacting FixYa.
Looks like they are push pin type if I got the right style #.
SHould be able to follow directions from here:

If this is not right, then you will need to take to local jeweler who has the right tools to do.

I have the same problem.  Following the instructions, by pressing A it wants to set the GMT differential. It will not go into manual receive mode.

You can do it yourself but proper watchmakers screwdriver is needed.
Check the sides of your bracelet and you will see screw ends with grooves. Unscrew them and adjust your bracelet (take the links out). Then screw them back in.
