Interesting! The font and 24h dial remind me of the Canadian market Oysters from the 30's and 40's

I did get it from Canada some months ago.

Similar style to this rare Canadian "Rolex Tudor." (Photo by watchestobuy) They didn't really solidify their vision for Tudor until the late 40's it seemsRolexTudorBoys.jpeg

Also did you see this eBay listing?

Up for sale is a vintage used and rare Tudor Donald watch. This watch is in great running condition, clean dial, and a clean Rolex 59 movement. The Tudor Donald dial is very rare!!

On the other hand, the Pioneer case is eroded externally as seen in pictures. Great for restoration.

The so-called "Rolex 59" caliber is really just Fontainemelon caliber FF30 with a few finishings by Rolex; it's the manual-wind movement that Rolex Canada used throughout the 30's-40's. I think your Dennison case is rarer than the Pioneer cases as far as Canadian Rolex/Tudor/Oyster watches go.
