I am new to this forum, but have been an Omega Forum member for some time. I am considering the purchase of a Grand Carrera Caliber 8 GMT. The model number is WAV5111. I have not been able to find pictures showing the full range of the GMT dial in the GMT window. So here is my question: is the GMT dial a 12 hour or 24 hour dial? Also, Are they all black markings on a white dial, or are there variations. I am also considering a similar Caliber 17 GMT. Haven't completely made up my mind yet. So far I am thinking the size and heft of the Caliber 8 is more to my liking.
