Hey all. Finally got around to opening my Nivada Aquamatic and am hoping that the movement pics will help shed some light on the origins of this piece.
It is a gold case, with a gold guilloche dial. The dial reads "Nivada Grenchen Aquamatic", and the caseback reads "2251 J14k". The J is stylized and is almost definitely a goldsmith mark.
The watch is automatic, and the movement reads as follows:
On the rotor:
Nivada SA Grenchen
Seventeen 17 Jewels
Under the rotor:
To remove hammer assembly
unscrew 2 screws A
Obviously the last part is servicing instructions (nice of them to include...) but the rest is gibberish to me. The movement is signed COW, for Croton.
Anyone have any idea on the date, provenance, other interesting factors here?
