Is there a 'golden rule' relating to relocating a hairspring onto a balance staff with regards to getting zero beat error after it has been removed for attention. I usually take pics or use marker pen but sometime forget!
I received a lys Longines 5L for cleaning. Upon opening the case, I saw some surprises under the balance bridge.
I have outlined my steps on how I uncoil a tangled hairspring in hopes that others can benefit by this method.
I’m a new member and new to this ‘hobby’. This site seems to be where it’s happening.
my very first attempt is with a BFG 866 which I have stripped cleaned and rebuilt. Not applied any oils or greases yet as I plan to do this a few times. However... I have noticed that the hairspring has come detached from the ‘cock’ plate? I cannot see nor find how this is reattached... is this broken?
Any guidance is much appreciated.
I need help with removing and then putting back in a hairspring that has a friction fit stud. I know there is a special tool one can use for this purpose. Does anyone have any pictures and know who might have made it? Can anyone "walk me through" how to remove and replace a hairspring without using the tool? Thanks!
I have a few old Vostok 24xx movements which seem perfectly fine except the the hairsprings are ruined. Most of these movements have come from eBay sold as “for parts or service”.
So, my plan is to buy a few new balance wheels complete with hairsprings (like these) and replace them. (I just haven't got the tools or skills to just replace the hairspring).
I have a pretty good idea about how to remove the hairspring stud (like this, or is there a better/easier way?), but how do I remove and re-fit the hairspring from the regulator arm? Can it just be lifted off and re-fitted with a tweezers, or do I need some special tool or procedure for this operation?
I haven’t seen any instructions or videos about this, perhaps because it’s so easy or obvious? Well, at least that’s what I’m hoping!
Hello again, so on a movement like this, the escapement wheel teeth or pallet stone jewels (not pivots ), I would use moebius 941, and on the balance jewels, I would recommend moebius 9010. I think using the 9501 which is recommended for friction areas like the canon pinion and chronograph parts, is going to be too think and would reduce the amplitude and also the 941 for the balance jewels. Please let me know if this helps, best of luck. Anthony
If I’m not mistaken Tissot still provides time pieces for officers of the IDF today. I ran across a newer one for around $4,000. A chronograph as I recall, never worn.
