yes it is indeed made of SS and Ti and let me tell you that it is absolutely fantastic. remember that this particular model is an extremely limited edition from a few years back and anyone that knows what the shade the dial should have or the distance of the bulb to the center pin will ALREADY know that it is a rep for any one of 15 other reasons. not just reasons to this particular model, but to all pams. things like the 'flick' of the lever on the CG or that 1 extra mm of thickness of the crown itself or the luminosity of the dial and hands or the shape/depth of the rehaut or the font of the tachymetre numericals or the fact that the gen doesn't come on bracelet (apparently, i'm not 100 percent sure of that, only 99 percent sure) etc etc etc.
all of that being said, this one is absolutely amazing. probably my favorite of all of my pams. not to mention that the venus copy movement inside has been rock solid and dead on accurate.
buy this watch.
