Ebay have that spring. The only address I can find is this, but I don't think it is any help.

Thanks for your input. I have been following the springs offered by schillachi61 and will use him as a backstop. I'm not in a  bind on this one as I had a spair,  just looking to replace it. BTW, there is some good info in his sale. It appears the following models use the same MS "Seiko 6105, 6306, 6309, 6117, 6106, 6119, 6118, 6319, Mainspring"  PN 414615. The 6139, 6138 Seiko BOM calls for PN 414616, but he claims it works and I assume it's the same.

After watching @Mark video on measuring and ID'ing a MS using a the GR catalog, I was able to find the catalog online and find the GR code. Now, with the code (GR Code: RA1S04958, GR Ref:: 2534-X) who supplies GR spings by code number?

I would think valume repair shops are going somewhere to order MS by dimensions & config. The difference in cost would be $3-5 vs $30.

Thanks again

I have never found a MS on CousinUK using their search feature.  Yesterday, I was looking up a MS for a cheap  Gruen and entered the measurements I made and got nothing.  I even fooled around with some of the measurements hoping for a hit.  Have I gotten a bad url or does COusinsUK just hate me?

Cousins probably just took a dislike to you. Don’t take it personally :D

I usually enter the bare minimum of information, i.e. height and end type and see if any of the results are workable

 

That's probably good advice.  I have probably been too specific with my searches.


Thanks,

Just throw this in- I order direct from GR as a "manufacturer" but it's the same deal for guys I know who order as repair shops; the springs are about 25 bucks straight from them. If you find cheaper these days it's old stock from suppliers who didn't adjust their prices or don't replenish their stock. I remember fondly the days of 7 dollar mainsprings.

I don't know if this would help but I have ordered the exact mainspring -- for Seiko 6309A movements -- from cousinsuk.com . I'm also from Norcal but have found that none of the US vendors use GR codes and their websites are extremely hard to navigate when ordering parts. With Cousins, I just type in "GR2534X" in the search box and they will show you the item listing. I usually order a bunch of mainsprings to save on overseas shipping (it takes about 7-10 days to reach the US and clear customs, which is quite fast).

    • So, I'm gonna try and post a couple of photos shortly, both Seiko of course for reasons stated earlier.   The blue one is apparently called the "ashtray" bezel. It winds, works, keeps good time, over the last 8 hours anyway, the only snag being the day pusher function does not operate every time.  The silver one is a Seiko deluxe which does not wind or work, in fact it makes a disheartening rattly noise when shaken, like something has come adrift inside.  They were purchased as items for me to take apart and study, then hopefully reassemble, having cleaned and lubed.  The ashtray arrived from India today, the deluxe arrived from Japan today, both were ordered last midweek. How easy these days to begin a new hobby, what with international freight, the Internet, and training vids on you tube. I may not even renew my porn subscription, this hobby could save me money!!!   Next purchase will be a set of intro level tools, then to business. 
    • One option for white is to use a toner reactive foil. This is what I used with success: https://www.circuitspecialists.com/pcb-trf-white.html I didn't use decal paper for printing but used toner transfer paper. My presumption this would still work with the film-less decal paper. Getting the toner reactive foil to work is tricky though. It requires both heat and pressure. Too much heat and pressure and entire dial turns white. Too little and it would only partially stick. It also requires some brushing to remove any bits of foil left over. It took a lot of time, practice an patience for it to work for me but it is certainly possible. I wouldn't recommend this on a dial you only have one-shot with, try with a blank you can practice with.
    • Ah yes, a coupla good ideas there!  I'll go find a welder and cadge a rod, that's a cheap option. Thank you fellas. 
    • Thanks, nickelsilver!  You mean, the first hairspring, the one still mounted is beyond repair? I haven’t touched it. If it is what you meant, it’s disappointing.  Thanks for the clarification on the vintage tools!
    • Can we have a look at the back. I'm sure the movement comes out from the back. That is not a waterproof case.
