Having flicked through the 'smoke and mirrors' thread and having been fully aware of my Tudor prince oysterdate having an eta movement, along with a large quantity of my watches it seems, i was wondering if anyone can tell me which luxury watches use movements which are entirely their own?
I presume Patek Philippe do, as do Vacheron Constantin, but who else? The older Rolex datejust movements are original or eta based? some seemed to have been Piguet?
Are my vintage 50s Omegas eta based?? I hope not and believe the contrary to be correct anyway. 685 etc.....
Thanks, good collecting to you all!!!
