In a "trade" with a Canadian, he threw in what looked to me to be an old (S/N207062) Waltham 10-12s Pin Set Stem winder. But the Signature: "Cahoon Bros., Donegal Place, Belfast" threw me for a loop. How about an expert opinion on what this is.

Very PLain Dial

Nice Silver Case

It will be interesting to see what the Waltham guys have to say about your watch

This is definitely NOT a Waltham product. I believe it is an English make. The hairspring stud and regulator are typical of some other English watches that I have seen.

It is clearly NOT Waltham, I am sure, and it appears to use a straight line pointed tooth lever escapement with 16 - 19 Jewels. As many as 5 pairs of pivot jewels, 3 pairs of cap Jewels, roller jewel, and 2 escapement jewels.

Now That I found it again in my "stuff" and as it appears to be in very good condition, I will make it all better next week and see what it has "in it" as far as a timekeeper goes.
WHAT A NAME! Cahoon Brother's! I love it!
