Need help to find an alternative Mainspring


Recommended Posts

Hey guys! I just broght a Universal Geneve watch with cal 1-42 movement. The dial is amazing and the price is very low so I dont even hesitate to buy it. But the buyer did notice me that the MS is broken so I need to replace one. Unfortunatly the original MS is out of stock, I can not find a original replacement. So I'm thinking about buying an alternative one.

I haven't receive the package but I dig some research so these are what I know now:

width of the MS: 0.9mm

Thickness: 0.10mm

Inner barrel diameter: 8mm

Length: unknown

It will be very helpful if you can help me find an alternative. I dont have a GR book so I dont even know where to start.

Thank you guys!

Generale Ressorts lists a 0.90x 0.10x 260  8 spring, which happens to be for their replacement for Movado 245 and Universal 820. Should work fine.

Thanks. But these two are not so easily accessable as well:(

NS has identified the approximate length you need. It is not critical. Just get the closest length you can. 
 

If you are UK-based then I can take a look through my sets if you can’t find something from Cousins.

GR catalog can be downloaded on Cousin's, click "documents" on any mainspring page.

Just checking if cousins can ship to my country.

Cousins ships to any country. In another topic you wrote that shipping to your one cost too much, I'm surprised by that since under ₤25 they can ship untracked at actual cost. I pay GPB 2.20 to EU, I assume it's just a little more for the Americas or the rest of the world.

I live in China so an untracked post is definitely not an option, your package will be lost in China for sure! I need three MS because I got 3 universal 42 suffering the same problem... And the cost of the shipping is €20. If unfortunately I get taxed in China I will pay €5~10. I'm still a postgraduate so I'm buying on a budget. That's why I'm considering other cheaper alternatives. If that's OK it will be a big relive because you don't know how frustrated shopping worldwide in China.

Find a friend or service to reship to you from the UK or other reliable country. I know that "proxy buyers" are popular, shopping on behalf of others, then smartly packaging and declaring goods to China.

Thanks for the advice. I will consider your proposal if it's available.:)

    • Depends where you are with repairing, watches like you have just mentioned  the Smiths, Ingersolls, Services are often pin pallet watches with low jewel counts, not impossible to fix but often quite difficult due to having more wear than a fairly standard 15 or 17 jewel movement. Saying that you may be lucky and pick one up that was never used much. As an example i spent a few weeks on and off getting the most i could from an old Smiths Empire, that did actually finish at within 2 minutes per week that could be improved further now i know it is fairly precise but not quite accurate . Sekondas are good practice pieces at around a tenner, though some folk call them rough but robust.
    • Hello people , this is maybe a question that the moderators can answer.  Can seperate posts be unmerged from each other. Sometimes posts are missed by others because of a continuation of them . Even when answering seperate people the posts are grouped together as one. Maybe it saves message board space ? 
    • Just got these good quality diamond files from the bay for Just a fiver, we all love a bargain dont we. Brand names are J.K.Smit  and Triefus, two old diamond tool makers so not cheap crap.
    • Its a touch under ive just remeasured it and added a wrist shot. Unbelievably it was £13  plus 3 postage. You dont find watches that nice for that money every day of the week. Maybe removing the epilame in the oil region improves the purpose of it. We may know very soon as i emailed Episurf 4 hours ago to ask that exact question. 🤞they are happy to provide an answer for us. How do you fancy trying a stearic acid vapour treatment experiment  H .  Shall i have a go this afternoon ? Stearic acid experiment underway,  its started to melt at around  65° C. The idea is to find a large cap jewel to suspend over the vapour release. 
    • That's the size of my grandfather's Ernest Borel watch. Definitely not a lady's watch! 👍
