I was at my neighbourhood watch shop when I stumbled on the owner's stash of old catalogues. I was looking through a couple when I saw this old Tudor catalogue (well not that old, it was from 2006). Inside I saw these. Never knew there were 4 different models. It is the Tudor with the California dial.
The Tudor Prince Date Day reference 76200-62480. This is the largest at 36 mm.
The Prince Date reference 74000-62470 and this one comes in at 34 mm. The next model is the Prince Date (boys model?) reference 72000-62450 and this one is 32mm. The last model in the collection is the Princess Date reference 92400-62430 at 25mm.
