I suspect it will have an Adolf Schild Ca. AS 1463 inside:Yes , it's digital power-reserve indicator, I bought it very cheap price at market, someone offer me 100 Euro, prefer to keep it for my self
Richer, when fully wound the number on the power reserve is 44.I suspect it will have an Adolf Schild Ca. AS 1463 inside:
bidfun-db AS_1463: AS 1463
...the same as the AS 1382N but with the power reserve by window (rather than with a rotating hand). Alternatively a Felsa Cal. 699 Permutator:
bidfun-db Felsa_699: Felsa 699 Permutator
The AS calibre has 36 hours power reserve, the Felsa 44. The maximum number on the power reserve when fully wound should help identify it.
