Just bought the blue titanium speedmaster and its ticking is noticeable when compared to my Rolex GMT-Master 2 which is completely silent. Could the noise be a result of the non-metal back?
Different watch, different movement and different material the variation is to be expected really. Having said that I've never owned a silent Rolex or even one that could be described as particularly quiet.
Except for manually winding my Rolexes have all been dead silent. .. when manually winding... it purrs like a kitten... But back on topic:quite normal... in general less waterproof watches are ticking louder especially vintage ones
