Practice with shock spring


Recommended Posts

Had a bit of practice fitting a shock spring which was fun, and ended up making a little tool to fit it back into the movement.

Anyone know what the spring is called, movement is a Seiko 7S26.

Many thanks from Jon

That looks useful!

What the spring is called? It's a Diashock i.e. Seiko's shock protection system.

Thank you.

I can only seem to find pictures of the flower type design and not the one pictured above so was a little perplexed.

Only seen them on newer 7 series movements and some newer Seiko movement. They are a pain in the ....  to put back. 

Agreed.

I played around for a couple of hours, then left it till the next day and made my little tool which did the trick.:woohoo-jumping-smiley-emoticon:

    • I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.
    • There are some parts on Ebay for the seiko 6020A, it may just be a waiting game for someone to strip one down, NOS will be more scarce . K would strip your movement down to the module then start looking at other seiko movement to see if that coil is used, then seek out a seiko part dealer. Also Retrowatches youtube owner Mike may give you some advice try him on his site . He also hangs around amateur watchmaking groups.
    • I would agree, in order to work harden something you need to exceed it's yield strength when it moves from the elastic zone to the plastic zone and you get permanent deformation and work hardening which is fairly close to its failure point, relatively speaking and dependent on the material/alloy of course. In theory you can load something constantly within its elastic range and not suffer work hardening issues.
    • Probably easier to get a complete new movement - but CousinsUK list it as discontinued. Maybe someone on here knows a substitute movement ?
    • Any other thoughts on how I can get a replacement coil? Any “hidden” or unknown physical shops (in Australia or elsewhere) that might have them in stock (but not always online)?
