That?s correct!

Actually the ref. 25930 is discontinued since 3 years ago; the current 25932 is the only model with this case size.
Over the years, there have been quite some dial variants for the 25930. For a rough overview of some variants, you may have a look here:

Of these dials, there?s some stock at GP Switzerland. This allows for dial changes, but not every colour or execution variant ever made is still available these days.
So best to do is to check back with a GP AD for availabilty.
Changing the dial is something most GP Service Centers and many GP dealers (at least here) can do in little time, so you won?t have to send it in.

The 25930 is a very nice watch, particularly the WG and RG variants.
Personally i like the classic dials like 115/216/615 a lot and it makes for a timeless look. On my wrist the 25930 doesn?t look small; the relatively thin and curved case is very comfortable. I greatly love these
Just that "common taste" prefers the larger cases such as the "Kingsize" models. The current 25932 is a bit of an "uni-sex" model and between the classic men?s and classic ladies models, but with some decidedly feminine dials in the lineup. It?s not a typical ladies watch in my books and i find the classic dials to be perfectly ok for the guys, though.
Still if you are used to wear 40mm round cases or larger, the larger cases may be worth having a look at!

As an alternative with a slightly larger case, the (discontinued) ref. 25990 column-wheel chronograph might be interesting. It?s a higher and slightly wider case, which wears a lot larger due to the chrono pushers. And it?s the only men?s watch to sport GP?s own chronograph, which makes it pretty special inside and out.

Cheers,
