A GMT 2836 movt. is a hybrid, of sorts. An extra gear is added- a reducer for the GMT hand which makes one revolution for every two of the hour hand. This is a modification made in China, so sometimes the quality of the mod is good, sometimes not so good. The ihs mod is fairly simple and pretty reliable. As for parts, I doubt you'd find them as a do-it-yourselfer.
