    Another identification job - Nivada Aquamatic

    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
    Croton
    E3TE C555

    Under the rotor:
    Unadjusted Swiss
    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?

    Thanks!

    Nivada made pretty good watches I believe this one has an early ETA movement.

    Yes, it looks like an ETA 245x. Nice Nivada! Can You do a close up of the dial - it seems to be very pretty!

    Sure, it was a bit of a job as the guilloche is so fine but I hope this satisfies

    An interesting update to this post - I thought I'd mention that despite being as young as 50 and possibly as old as 70 years (and probably never serviced), this watch started up on the first shake. And now that I gave it a proper power reserve (the movement handwinds), it has lost less than two seconds in 12 hours.

    This is the only one I have, but it's pretty cool! It's so small though... the entire watch is smaller than the face on my Chrono Avenger. I'm still hoping someone has some idea what year it's from!

    It's impossible to date accurately. The fact that it has a 245X movement means pre 1970 the dial and hands suggest the 50's. If the watch is less than 32mm it really suggests pre 1965 and more likely pre 1960 but that's as close as your going to get.

    Ah, OK. I could tell from the dial and the history of it that it had to be around that timeframe. I was hoping those random characters on the movement would mean something to someone. Thanks!

    I would guess it dates from the late '50s. From an industrial design standpoint. Looks like a speedometer from a 58 Buick to me!
