I have been given the watch by a dear old lady and I have had it cleaned by Rolex dealers. Unfortunately I have forgotton to ask them the name and model number, as well as replacement of straps etc. It is a very dainty piece and I am thrilled to bits to own it. I have attached a copy of a 1953 advertisement on which it appears but I can't find any further information about it. I did speak to Tudor watch dealers in london but they have lost a lot of their old records and such. I see lots of stuff about oysters,princes etc but nothing about ******tail watches. I would be grateful for any help or info you could let me have.
