I was hoping I could get some info on this watch I have from some of the resident experts here or anyone that could shed a bit of light on this thing. It's an Eterna Challenger "Birks" pocketwatch. It was my grandfathers who passed when I was a kid 35 yrs ago. It was given to him by Canada Steamship Lines and has an inscription on the back for 25 yrs. of service. The date in the inscription is 1953. It's a 17 jewel Eterna in a Keystone 14k (gold filled I think) case. I now live in Ohio and nobody here has heard of Birks and I explain Birks was like Tiffanys down here. Anyhow, big question is: Why can't I find anything about this watch? There just seems to be zero information on Eterna pocket watches. Checked online for Birks commissioned watch makers and Eterna brand movements and still cannot find another one that has this large Eterna movement in the Challenger design. The chain and pocket knife seem to be gold plated. All this has been under a glass domed display thingy and has just sat on my dresser forever. I'd like to get a guesstimate on value if possible. The pics don't do it justice. It has no scratches on the open face that i can see and wear in minimal on the case. The Eterna movement is totally mint and works perfectly. Thank You Thank You for any input.
