I have run into a bit of a roadblock with my 7017-6010 Speedtimer project. Looks like I need a S-510 movement holder or something equivalent. My Bergeon 4040 will not work. Any guidance on where I can purchase the proper movement holder or something aftermarket to meet my needs is appreciated. John

Get this for your 7017 and don't think about any other work-arounds:


https://www.ebay.com/itm/VTA-S-510-Handsetting-TOOL-for-SEIKO-7016-7017-7018-Chronographs-NEW-GOLD/292963420287?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D20131231084308%26meid%3Db33494cc83574727bc2ea11f0870d144%26pid%3D100010%26rk%3D5%26rkt%3D12%26sd%3D292095194415%26itm%3D292963420287&_trksid=p2047675.c100010.m2109

BTW, I have the Seiko OEM S-501 and the VTA version for the 6139, the VTA is hands down better.

And do not let anyone tell you these AREN'T (thanks Guy for catching my typo) needed. They just haven't trashed a chrono wheel or bridge yet. Ask me how I know :(

Perfect. Thank you very much. Just ordered one.

At this time I have the winding weight off and have removed the hands and dial. I am using a small plastic case holder with adjustable plastic feet. Is there any danger in continuing the disassemble the movement without the S-510 mvmt holder or should I wait? I know the mvmt holder is necessary for the buildup and for properly setting the chrono second hand. Thanks for your advice.

Yeh carry on. It's for ease of testing pushers and setting the chrono aseconds hand install by making sure the jewel isn't buggered or displaced by the pivot.

You meant "aren't" Jon.

I have this version and I like it a lot. They come up now and again, but the VTA ones will be fine I'm sure.

Firstly Thanks for catching my typo Guy - since corrected !


OOOOh the S-620 I've never seen that one before.

Nothing beats an original.........But, when one isn't available, Adrian's are the next best thing.

Jon, not having a VTA version can you explain why? I might have to get an order in.
Well this is very interesting. I just pulled my 6139 hand setting tools and it turns out I have the S-500, not S-510. The instructions are only in Japanese so I sure can't understand the words but the illustrations tell you fine. Note the numbers inside circles versus the others not inside circles.

It seems to reference the 6139A only, maybe the S-500 preceded the S-510?

To your question Guy, I find the VTA holds the movement more snug and of course I prefer having the start/stop actuator to run it through the paces.

The latest and greatest VTA version even has a 6139A vs 6139B support adjustment. Think I might have to get me one!

Speaking of typos....;)

Going to back to this thread:
https://www.thewatchsite.com/34-wat...-depressing-flyback-button-while-zeroing.html
Hi
I have a few question regarding that method please
a. In a 6139, if I own a standard movement holder, how would you recommend performing this action. I cannot think of a steady way to depress with only one hand, while the other hand is busy pressing the chronograph hand in place.
b. Is this technique also valid in 8110A movements ?
c. Assuming I would like to improvise a holder for a 6139, can I can the mechanical drawings somewhere ?

Thanks!
I just use my Bergeon (other brands are available...) movement holder, zero the pusher and push the hand on. I've never had a problem with the jewel moving. The hand only has one position to go on because of the D shape shaft.

When I fit aftermarket hands it might take me two or three goes to get then in the right position as there is no D to align.

Worry a little less about ipad autocorrect Paul you might try to learn from this thread.

For anyone questioning the need for one of these movement holders to support the jewels while installing the chrono hands, You're better safe then sorry.


Can it be done without the holder that supports the jewel? Yes, it can but as Jon has previously mentioned you stand a chance of dislodging one of the jewels during the process. These chrono hands need more then moderate pressure to install them to "seat" on the pinion properly in order to withstand the inertia they receive during the re-set procedure.


Keep in mind: Used hands have already had their tubes stretched a bit and install easier then new hands. New hands Take at least twice as much force to install them, especially the chrono second hand.

Can an S-510 movement holder be used for the cal 6138 and 6139 or do you need the specific movement holder S-500 for these cal?

You'll need the correct movement holder for the movement you're working on due to the jewels being located in different locations.
