Can anyone tell me who the USA supplier for GR springs are?

I am trying to find a mainspring for Seiko 6139 which of coarse are discontinued. 

I have found a GR chart and matched the demention to a GR8 code and now looking for a supplier. 

MS INFO

Seiko 6139 A/B mainspring measurements Type: X (Auto - welded brae spring) Length: 425mm Width: 1.03mm Thickness: 0.12mm Barrel ID: 11.mm Strength: ? Based on measurements ( GR Code: RA1S04958, GR Ref:: 2534-X

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).

    • Hello and welcome to the forum, the best path to take is to get some medium priced tools , look at Cousins UK . They are a material house and are open to all. There medium priced screwdrivers are middle of the road and wil if looked fore serve you well into the foture I have added a little reading for you to help.  TZIllustratedGlossary.pdf Watch_tools_tipps.pdf
    • After another long hiatus (while waiting for truing calipers to arrive), I’ve made some more progress. TRUING IN THE FLAT I was able to use the calipers I purchased to true the wheel in the flat. There’s still a very slight eccentricity in the round, but I’m going to leave it as is. It doesn’t wobble any more and I’m happy with that. Thanks for the tool recommendation @mbwatch. It worked well, though I must say it takes a delicate touch to get the balance between the calipers. Also, my calipers effectively have four different variations based on the orientation of the arms (2 sides, 2 orientations each). Some are more tapered than others, though to what end, I can’t quite tell. My first thought was that flipping them over yields arms that can be used for poising. They are K&D horizontal calipers, btw. OSCILLATION TEST @nevenbekriev @JohnR725 After truing the wheel in the flat, I carefully remounted the hairspring and did your oscillation test. Balance wheel mounted to balance cock, no pallet fork, rotate balance wheel 180 degrees, let it go, and time+count the oscillations. Results as follows for dial down orientation: Duration: 1m 15sec (to full stop) # of oscillations: About 125, though the amplitude of the oscillations decreased significantly, as one might expect I should redo the test in at least two other orientations…Forgot to do that. 🙂  In general, it’s safe to say this watch has a pretty low amplitude, likely for a variety of reasons. I haven’t oiled the balance jewels FWIW…I should probably do that, but I really don’t want to keep disassembling and reassembling the balance. Is it possible to oil those jewels (top and bottom) by just removing the capstones and putting in a tiny amount of oil, with balance in place? I can see how having the pivot in the jewel hole could change how capillary action works, and thus might pull more oil in than desired. However, those capillary forces will be in effect anyway once the balance is inserted. PRACTICE MOVEMENTS @JohnR725 I agree with your sentiment about using practice movements wholeheartedly, and I’ve done that to some degree. The watch I’m currently repairing is for a friend, and she was willing to have me treat it as a “learn-by-doing experience.” With that said,, I probably should have purchased a few more “beaters” before getting to something where I don’t want to muck things up. I’ve still got a couple of those on the bench that I used as donors, and I’ll try to rehabilitate them.
    • Hi, this is the first place I found when looking for advice so I hope someone could advise me.  Im completely new to touching watches but I’ve always wondered how they work.  I’ve bought a cheap movement, an ETA replica to take apart and rebuild.  Im thinking I’ll need some screwdrivers, tweezers, movement holder and a loop? My goal is just to have a go first and see if I enjoy it enough before buying more tools.  Do I buy cheap tools for now and get better quality tools later if I enjoy it like I think I will? or will the cheap tools be a pain and take some of the fun out of it?  With quality tools being relatively expensive I’m unsure what to buy.    Any advice would be greatly appreciated!
    • Yeah I have seen 44-56 documented for Elgin 18 size elsewhere. I have the style of gauge that's like a set of feeler gauges and I never noticed before today it is faintly stamped "Elgin". Pictured is the way I have been measuring. I am going to go to a larger jewel than the 42 that had been in there. I recently won an auction on a big set of Fitrite jewels all in the little bottles, to discover that the what's actually in the bottles bears no relation to the chart of sizes printed on the box. In most cases it seems to be all mixed so in fact I have about 24 little bottles and thousands of assorted jewels of all diameters and lengths, which is better than nothing. But since I don't have a micrometer with a table, measuring for the exact diameter will be a big job. Instead I will test a lot of them in the fork slot the same way I measure with the gauge. But this is still the next thing. I have to get the escapement to unlock first.
    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.
