*GASP!* (Rollie Guy infiltrating the Breitling area to post!)
...I would like to know about this too, but not for the SA, and just for my GMT-IIc.
It´s my second one, and the first one had an tight bezel with solid clicks, but this second one is a little loose as you said your SA is.
I heard the construction structure of the GMT-IIc bezels is different from the other Rollies now (bi-directional and with less clicks) So I´m relutant to stick a blade between the bezel and the watch and try to pop it out.
Gonna ask the mod experts around too, but I haven´t seen any GMT-IIc disassembled yet by anyone.
Cheers,
Spirit.
