    Universal geneve unisonic wrist watch

    Hi Looking for some infomation on my Dad's Unisonic, it is a 18k housing with a black face unisonic movement, diamonds onthe face and a date at the quarter mark, would like to know year and possible value, also looking to change strap, what would have been the original strap, and what mm strap would fit?

    Thank you in advance

    Sorry, the stickies (articles at the top of the forum) say why we don't do valuations.... a common question though.

    A pic of the movement would be needed for better dating but I think "Unisonic" was used in the '60s by UG.

    These expandable bands often gouge the lugs of the watch. I'd swap it out. (And service it... using it with dried lubrication will ruin it even if it will run.)

    Your Dad has good taste!

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    "Unisonic" points to the fact that it has a licensed Bulova Accutron (tuning fork) movement. Sort of an in between thing between mechanical and quartz. It still needs servicing and requires someone with really good experience in tuning fork watches - the connecting wire between tuning fork and watch is extremelythin! Once up and running, it goes at a frequency of 360 Hz (mechanical high frequency movements run at 5 Hz and above!) which means, it doesn't tick - it hums! At a tone close to the F# above middle C to be precise.....

    Ah yes... I was thinking of the Ultrasonic (Enicar?). The Unisonic is a variant of the Accutron 218 I think.

    Here's a little write up on the Unisonic from the Crazy Watches website

    UNIVERSAL GENEVE 1-53 UNISONIC 218 ACCUTRON 1965

    And with tuning fork watches, it is generally recommended to have it serviced before starting it up with a battery.
    Very robust movement that could potentially destroy gears if not properly lubricated, etc.
    I've got more Converse sneakers than watches, but it is a close race.

    I'm curious to know the straps size. You can measure between the lugs to get an idea
