Bracelet: Without a bracelet, I plan to have (when I don’t know) a bracelet made just like back then.
Other info:
- Of my Gruen, she’s the one who makes the most noise: tick tock, tick tock.
- The gold-colored crown is not particularly attractive.
- The dial has developed significant yellowing beneath the crystal.
- In photograph number 4, the small "bear" standing on the side of the case is the official Swiss hallmark for silver watch cases of 0.875 fineness or higher, used from 1882 to 1934.
- I'm sure you'll be able to tell me many more details. ;-)
