Seiko 6309A Rotor Bearing?

[64americandeluxe]

I was contemplating the purchase of a Seiko 5 (online) and noticed in the pictures of the movement that it looks like the oscillating weight has been rubbing on the movement.  I assume the bearing the weight spins on will need replacement.  That bearing seems to be part of the frame it is attached to (according to the Seiko parts list) and not a separate piece.  My questions is, can this bearing be purchased and installed separately?  I am waiting to hear back from my local parts supplier to see if the bearing and frame assembly is even available.  The auto mechanic in me wants to remove the old bearing and install a new one in the original frame.  Here is a pic of the movement and what the complete replacement part (Seiko 193 601) looks like...

Cheers!

Hi Roger,

 

I believe that part will be either hard to get from a supplier or very expensive considering this movement has been discontinued for many years. CousinsUK list it as obsolete (that's where I get my Seiko parts). You may have an option buying a donor movement from ebay or something...unless you find someone that has one around and want to donate/sell it to you. I usually prefer the 7S26/7S36 and newer movements to work on because of parts availability (mainly).

 

Have your thought about do a complete "transplant" and use a more recent Seiko substitute movement? On the other hand, it might just be a matter of tightening the rotor screw...I bought a Seiko once with the rotor almost loose inside and after tightening it worked perfectly.

Hens teeth are a lot easier to find, not an uncommon problem on the earlier Seiko's. Just keep an eye out on fleabay for a donor movement.

To my beginners eyes those marks you see (the brassy coloured arc?) Doesn't look to be caused by the rotor. Not defined enough and the ones I've seen are dark in colour.

That kind of damage certainly points to a worn bearing, if you look closely the weight has even managed to rub against the edge of the spring barrel.

Try

Speedtimekollektion.com they are a bit slow in delivery as the company is based in Spain but they do carry a lot of used old movement parts.

Thanks for all the helpful insight everyone!  I haven't bought the movement yet so will most likely pass on this one and try to find a Seiko 5 with a movement I can source parts for.  My local supplier also confirmed they no longer carry the rotor bearing assembly.  Clockboy, I will check Speedtimekollektion when I get home from work tonight for future reference - thank you.  Bobm12, I hadn't considered a transplant as I was hoping to buy a Seiko 5 that had a useable movement, but you certainly opened up some other interesting possibilities that will get me thinking in a new direction.

Have a great day!

So I couldn't wait until tonight to check this site out clockboy, so I just went online and they do have the part! http://www.speedtimerkollektion.com/shop/index.php?cPath=32_97_116  I'll have to make some decisions now about the cost of the part with shipping and determine if I'll purchase the watch.  Have you purchased from them before clockboy?  Would they ensure the used part is actually serviceable?  Thanks again!

Very good link clockboy I also saved it! Thanks.

I have used them a few times this year and parts are used but perfect for an old watches when new parts are not available. It,s either use the used part or scrap the watch.  They do give a 10% discount on your next purchase.

Use them myself AOK, however they are based in Spain but most of their stock comes from the Philippines.

[bobm12]

Maybe they just buy broken stuff from ebay and inspect/recondition them and resell.

Ok, I have already spent waaay too much time on this site!!! :D 

[clockboy]

The preferred option is to fit a new part. But if not available there is no other option. After Swatch drop the hammer next year we might as well get used to this scenario. If it is for a customer then we will just have to be honest with the clients.

Hi guys,

 

Talking about this sort of problem and identifying it, there is a nice picture of another Seiko here: http://www.watchrepairtalk.com/topic/1145-seiko-6106-movement-in-loving-memory/

 

Lawson made this strip down and maintenance thread and also talks about this. Thought it helps too.
