If it is true, the landlord's Tudor is a Prince series or a Junjue series, model 10DI, you are talking about a gold bracelet, and all the gold ones are 18K gold. The watch movement is ETA2824/ETA2834, and its polishing is far better than Longines.
Now this new watch is still a replica, Tudor watch and Rolex watch belong to the same company, so if this watch is real, the conservative price is above 2.3W
