The three current Oystersteel GMT-Master II variants share the same in-house caliber (3285, ~70h power reserve, Superlative Chronometer) and the same dual time-zone function. The choice between them comes down almost entirely to the bezel — and one design detail only one of the three has.
Two-tone black/blue Cerachrom bezel. It has a Cyclops lens over the date, like most of Rolex's date-equipped sport references. It's the most understated color contrast of the three, making it the easiest to wear daily.
Two-tone red/blue Cerachrom bezel, the color most historically associated with the GMT-Master name in popular culture. Also has a Cyclops lens over the date. Same technical specs as the Batman: the difference starts and ends at the bezel.
Two-tone black/green Cerachrom bezel. It's the only one of the three Cazador has documented WITHOUT a Cyclops lens over the date: the sapphire crystal sits flat, breaking from the rest of the GMT-Master II family's visual identity.
If you want the cleanest date read, the Sprite is the only one without a Cyclops lens — decide whether you like that before anything else. Between the Batman and Pepsi, the choice is purely aesthetic: same caliber, same certification, same two-tone Cerachrom bezel, different color.
