Somewhere deep in an forgotten drawer I found this old travel alarm that my mother used quite some time ago.
As you can see in the pic the brand on the dial is Topmaster which is/was a brand of Bueche-Girod SA in Biel/Bienne.
There's an AS 1475 movement inside.
The size is about 5 x 3.5 x 1.5 cm (2 x 1 3/8 x 5/8 inch)
My question is: has anyone seen any other examples of this model and does he/she have any other info about it?
Thanks for your help and have a nice weekend.
press the black cover near the hole (wher a chain could be fitted??) on the right to open the case and then press your thumb on the knurled part on the left to flip up the watch.
The spring-hinged cover keeps the watch in place.
Hope my feeble explanation makes any sense to you.
And yes I know, the crowns have a different brand on them. But that's too long a story.
