I picked up this small wristwatch at a thrift store the other day - I was sifting through their box of cheap pieces when I saw it sitting there. A few twists of the crown and the thing was ticking again: a few ten minute tests proved that it still kept very good time. The perfect gift for my watchless girlfriend (it'll be her first mechanical, too!).
I can't find any information on it online. The face reads "Gruen Precision" and beneath it says "17 Jewels". At the very bottom it reads "Swiss Made". The metal back says Base Metal Back Stainless Steel, but on the inside of that back it says Prospect Hong Kong. Engraved on the movement, which is in great condition, reads Swiss, Seventeen, 17 Jewels, 227R, Unadjusted, Gruen Watch Co.
You can see some photos of it opened up below. If you have any information or can point me in the right direction, please do! I'm trying to encourage my girlfriend to be as into watches as I am, and I'm thinking that being able to give her some history will help tie her closer to it.
If you don't know anything about the movement, do you know if replacement cases are easy to make/order? The current encasement feels like cheap brass and it's bound together with elastic. The actual bezel seems to have been plated with a gold colored material but it's fading off.
