The unique structure that we’ve created when masterminding WatchBase makes it possible to browse by caliber and quickly get an overview of all watches that have used said movement – well, at least the ones we’ve added to our database.
One movement of which I’m pretty sure that I’ve got a near complete list of watches for is the Patek Philippe Annual Calendar Chronograph caliber CH 28-520 IRM QA 24H. I think only one reference of 5960 or 5961 is missing.. Can you tell which one?
PS – should you happen to know the reference number of the sapphire-set 5961, please let me know!
