Hi there,

welcome to this forum. Both watches you are keen on are not solid gold. Strap 16 is available in white and yellow gold color, but are gold filled. You are right the is a sweep second variant with long central second hand and as such it was a good model to take a pulse.
Strap 35 is as well gold filled, this time with an extra thick plating called "reinforced with gold". Thickness of the gold plating is about a third...
Strap 35 was only available in white gold color. I am not aware of a solid gold variant of this watch.
So what you might be looking for us a Strap 24 which is the cushion form, round glass, sweep second variant in solid white gold.

Best regards
Barney

Hi Dali,

the strap numbers come from "The Catalog", the only known document which had almost all Gruen watch models from 1922 to 1958. The standard mans models are the Strap line and they are simply numbered from the very first in 1922 to the last in 1958. It was recently digitally remastered by Mike Barnett and is available through Lulu.com -> http://www.lulu.com/shop/mike-barnett/the-gruen-watch-catalo g-economical-soft-cover/paperback/product-22412671.html
Afire is correct with the solid green gold version being Strap 17 (Although the catalog says yellow gold), the white one is the mentioned Strap 24. There is also a version in Sterling silver which is Strap 15.
