Vintage Challenge: 1934 Bubble back

[cactakla]

Greetings! Rolex noob here. I just received my late great grandfather's watch. It was passed down through the family (via my late great uncle and just now by my father) and I just took possession.

The case number is 310xxx. Following some research, it appears it was made in 1934. I've not seen this exact watch, but the elements are recognizable in other watches of the time (dial, hour/minute hands, case)... except for the second hand. I haven't seen a second hand without a tail, but I don't have access to 100 Years of Rolex.

Further, I'm not sure why a second hand would need to be replaced, so I'm a bit confused on everything.

I plan on getting it serviced as it's been sitting in a drawer for at least 15 years and probably longer as I never recall seeing my late great uncle wear it. Just wondering if I do something about the second hand while I'm at it.






Thanks!
