I just got back from the watchmakers who gave my recently acquired Thomas Russell Son wristwatch a CLA, now it's ticking away merrily. When I got it the crystal was broken with a couple of gaps at the edges, the crown has its boss for the stem knocked to one side; a new Robur crystal has been installed and the leaning boss in the crown straightened out a fair bit, but he is looking for a replacement crown.

It's my understanding that Thomas Russell's pocket watches are much more commonly found than their wristwatches; mine has a Swiss movement in a Dennison case measuring 30mm in diameter with 16mm lugs; obviously much later than their pocket watches. It has a white dial, with lume hands and Arabic numerals on the dial. The brownish lume is gone from the minute hand, and some of it has gone from the numerals.

I do not know if the lume material contains radium, I do not have the instrument for radiation detection, but it would be nice to find out. I am thinking: what if I put the watch and a some sensitive material, such as a piece of photographic film or paper in a sealed, light-tight canister, and after a while develop it?

REally a nice watch. The caselooks like the 1950 ties with a retrostyle face. Do you've a picture of the movement?
The dial looks like enamel. Many yearsago we's done this radiographic exposure to detect with C14, S32 or Tritium marked proteins in very thin tissue sections and direct contact to the film. We patch the film wet over the slice. It works but we used very sensetive special films, a very dark and chilled working room. I don't know if you can use a simple comercial film for detection through a plexisglas with a film in a cube even if Radium is a strong stuff. I would leave the clock like this. If you are a friend of the restoration, then I would let the Lumina completely ornately removed by someone who nows what he do and replaced with new Old colored Lunima.

SilkeN,

Thanks for the information. I am also looking into getting, or borrowing some sort of radiation detector for testing the lume, I do not know of anyone who can do the removal. While redoing the hands would be easy enough, there are the specialists who can relume the dial as the numerals are very small and any mistake would be very obvious; I'll proceed to get the testing done first.

As for movement, here it is; it's not branded anywhere so I do not know who produced it.

Hi there,

As for movement, here it is; it's not branded anywhere so I do not know who produced it.
I occasionally take posts like yours as opportunity to test the advanced search feature of my archive (top right on every page).
In this particular case it picked 5 movements out of 10,691, two of them being yours and a rebranded counterpart. Pretty efficient though, and you should try it yourself on this page:

Hi Roland,

Thanks for the tip, I shall be giving the feature a try.

Journeyforce,

Your Enicar is superb! As for my watch: being who they were I suppose Thomas Russell would have wanted a porcelain dial to give their products a sense of continuity, even though they use bought-in movements. I wonder: what's the case diameter and lug size?

Hartmut,

Thanks for spotting it as the Revue 59; the lack of shockproofing might be an indication that it's an earlier example between 1945 and 1959 perhaps/
