Seiko 6309A Rotor Bearing?

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!

Roger

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.

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!

Roger

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.

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!

Roger

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.

      Been there. Worn that Tshirt.  'ping'. Hands and knees. Nothing. Nada. 20 minutes? Ha! I found it 7 month later. How? Well, after advice from a member, I invested in a £4 UV light torch.  Hands and knees looking for a 'ping' from a Sekonda, found them both within 30 seconds. UV makes the jewel shine. easy peasy. Could have taken longer. Just lucky on the location of the search. Hope this helps.

      Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?

      Never and others. Yes, like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. Clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross

      Hi all, total newbie to watchmaking and I've had a bit of a mishap. Just completing level 2 and was doing ok, but I was just on the last part of the reassembly of my ST3620 when the balance end stone shot across the room, just as I was trying to see if I had put the correct amount of oil between it and the balance end, aarrrgh! Been on my hands and knees combing the carpet for 20mins looking for it but to no avail. Does anybody know where I can get a replacement from and what to look for please?? Thanks.
