Thread: Seiko 7a38-702a project

  1. #1

    Seiko 7a38-702a project

    Got this for pizza money from a Hong Kong seller as non working. Asked for movement pics but he said he had none. Had tried battery but no life.

    Decided to take a punt anyway as it's a 7a38

    First impressions were quite good.

    Then I opened it up to try a new battery

    Took the top plate off to take a look at the circuit block

    Started to look around for either a donor or even a circuit block. None at all

    Then I posted my anger and disappointment on Wristsushi where a very generous member offered a working donor

    It has made its way from NJ USA in 3 days and has arrived at Heathrow. Now the wait starts.

    Once here, quick movement swap and a really deep clean and I'll have my first 7a38 (next a 7a28 )

    nice when a plan comes together
    one night I dreamed I was locked in my fathers watch, with Ptolemy and twenty one ruby stars mounted on spheres and the primum mobile coiled and gleaming to the end of space and the notched spheres eating each other's rinds to the last tooth of time and the case closed - John Ciardi ...

    Should be a fun small project.

    Wonder what can be done about that bezel? Polished and replated? I used to have a home plating kit in a tub.

    Is it that good then ?

    I remember having a stepper motor chrono in the 80's/90's and just loved how they tracked back to home when reset

    Better than the 7txx movements that use plastic.

    7a28 would be even better as they were a milestone in watch history.

    Just searched for what I used to have.

    Medallion liquid 24k gold plating solution $35

    Can't find a UK seller yet.
    In the meantime, sent a quote request to a gold plating company. Let's see what huge number they come up with

    I used to to know a guy couple of decades ago ..... Mr Gent , and he was a right gent too .... for nothing he plated a lovely silver antique table clock for my now deceased stepfather.

    The company was one of those companies just hanging on on the outskirts of H&S
    I guess Mr Gent is gone now too.
