Hi,

Is it possible to put a new hole on the inner end of a mainspring, where it hooks onto the barrel arbor? I've a couple where this has broken off due to problems with my winder. The simplest solution is just to get a new mainspring, but I am trying to learn as much as I can so thought I would ask. I've seen various topics in De Carle etc., but they seem to refer to repairing the outside end of the spring and the barrel. Thanks

it is quite difficult to do this on the inner coil of the mainspring. It may be better to purchase a new one.

For the "academic" answer, I'd say, there is this pliers like instrument -- Geo shows one somewhere in the forum -- that allows to open a hole on a mainspring...now how to get to the inner coil and do it, that would be a trick! I would definitely go the way Mark suggests!

 

Cheers,

 

Bob

    • How do the timegrapher readings look after the watch has been running for 24 hours? Are you using a phone app or a dedicated timegrapher to take your measurements? Best Regards, Mark
    • From what I see, the crystal is made of mineral glass and is secured to the bezel with a sealing ring. If you might want to replace the crystal without removing the bezel or the movement, I think it's possible, but risky. You have to suck out the old crystal without breaking it into tiny particles. I would not do that. If you remove the movement first you can press the crystal out and press a new one in without removing the bezel.
    • Hello Everyone, A short message to introduce myself. I'm Sebastiaan (50) from the Netherlands and have always been interested in watches. My two kids are at the end of their teens years and so I have more time to start a hobby.  Working on watches was something I always wanted to learn. So I recently started the watchfix repair course. Currently watching level 3. My short term goal is to be able to service the watches we (Myself, my wife and kids) own. I own a manual Omega Geneve from 1974, a small microbrand watch with a NH35 and a wittnauer bumper from 1940's. My wife owns an Oris, Seiko 5 with 7s26c and my son a seiko alpinist sarb017 and sports 5 with 4R36. So enough to learn on the short term..  Looking forward to talking to all of you and enjoying the watch hobby together. Greetings Sebastiaan
    • It works quite well. The only strange thing is that it loses 2/3 mn per day whereas the measurements indicate that it is fast by 1/2 mn. Maybe something wrong with the gear mechanism ...
    • Unfortunate…but you clearly have a Longines branded movement with a year 1936 serial consistent with the caliber. I checked the case maker of the last few Longines I worked on… …same as your watch, so certainly you have grounds to honestly describe your watch as a Longines cal 25.17 tank with unbranded dial…and given the modesty of the watch IMO the Longines authentication wouldn’t dramatically alter the value, if that’s what you are hoping…as nucejoe suggests the value will mostly be determined by how well it runs…
