Hello from Utah, and a question

Recommended Posts

Hello,

Im pretty new to watch repair, just a few watches serviced so far.  This forum has been a big help.

As for the question:  I’m in the middle of a Slava 2416, and have a reassembly issue with one of the mainsprings.  I was trying to rewind it, but after a rather epic battle, I now have a mainspring fit for the trash can.  I’ve had no luck trying to source a replacement, including the cousins site, and am hoping someone can point me in the right direction.  I found a donor Slava 2427 on eBay, but I don’t know if that’s compatible.

thanks for any help!

OK in my GR catalogue it shows a Slava cal: 2414 and it’s mainspring is as follows:

GR 3919DB  the DB indicates it has a special bridal which is the shape of the start of the spring. It’s size is 1.45x0.075x240.

Cousins also supply the above as a complete barrel. 

The nearest size I could find re the sizes you have supplied is:

GR4059 1.50x0.07x240

there is also a GR4059DBH which is another shape of the start of the spring but Cousins do not supply that spring. 
 

You need to know the shape the spring see attached pic.

    • Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
    • Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?
    • Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.    
    • Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?      
    • Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
