Tudor Watch Identification?

I’m not near my reference material at the moment, but IMO, your Oyster Tudor is likely 1940, or thereabouts. The way I read it, at one time, Oyster watches were a range unto their own. Subsidiary to Rolex. Since the Oyster design case was used on both Rolex and Oyster, Rolex was selling Rolex Oyster watches, AND Oyster watches. Oyster watches became TUDOR watches, so Rolex could use the Oyster name on both Rolex and Tudor watches. Your watch pre-dates that. I am not certain as to when Tudor became the name of the companion line to Rolex, but it seems like it might have been in the early to mid -1950s, or thereabouts. By the 1960s, Tudor watches were a range unto their own, and had a logo on the dial. Either the Tudor rose, of the later shield shaped Tudor logo. So the way I see it, yours fits into sort of a transitional period in time.

I was in the retail jewellery business in the 1960s, selling TUDOR watches. And my late father was in the jewellery business in the 1950s, selling Tudor watches. By the 1960s Tudor watches were badged Tudor. And they were all equipped with KIF shock protection. The subject watch is not. And they used ether the Tudor Rose or the Tudor shield on the dial. That watch is most definitely not from the 1960 era. You can take that to the bank. I am not aware that a reliable serial number/date chart exists for Tudor watches. That watch is from the 1940s! The Ranfft archive is reportedly not totally accurate but it is a good guide. Take note of the era when the FHF 30 (Oyster calibre 59) movement was produced.

Not a Rolex movement in any sense, but an FHF-made cal 30 re-badged as a Tudor 59, which is certainly correct for this model. As @Canuck mentioned, the lack of shock protection suggests that it is from no later than the 1940s.

The image I have uploaded is of a Tudor watch sold to a family member by my late father when he sold Tudor watches in his jewellery store.. This watch was sold in 1955. It has had a hard life. It was sold to a cousin of mine who worked in construction, he was a millwright, and an auto body mechanic. It was originally sold in a gold filled case which was not up to the use it was given. I re-cased it for him circa 1985, in a steel Rolex case. Note the dial. By the late 1950s the TUDOR name was prominent on the dial. At this time, Rolex sold Rolex watches and Tudor watches, both using the Oyster name. This one was known as a Prince Oyster Date. The Oyster name was no longer dominant, but secondary to the TUDOR name. Also, notice that above the TUDOR name is the TUDOR ROSE. This is how Tudor dials were marked after about the early 1950s. If you need more examples of Tudor dials of the ‘50s and ‘60s, I have them. Back to the watch owned by the OP. IT IS FROM THE 1940s!

This dial perhaps better shows the dial markings for Tudor, in the 1950s. Notice this is a TUDOR watch, after Rolex changed the name for Oyster watches, to TUDOR, for their subsidiary watch brand. The TUDOR name is dominant, and you will notice by the 1950s, the Tudor Rose emblem was added to Tudor dials. Until this re-branding occurred, the OYSTER name was dominant, and the Tudor was secondary. And there was no Tudor Rose on the earlier dials. Rolex began to realize what an asset they have in the OYSTER name, so it was used to signify an Oyster case on both Rolex and Tudor watches.

The private numbers watch repair people use are often meaningless to anyone but themselves. Unless you see a number like 09/17/49 (for example), it is anybody’s guess when it comes to interpreting these numbers. Don’t confuse numbers that are die struck into the interior of the case back by the case maker.

Probably not going to find that dial anywhere else as it appears to be a pretty bad redial using typography from an earlier watch.
