I recently had the pleasure of finding a damaged hairspring needing care. My first! It’s an inexpensive orient watch, gaining 20 minutes a day. I am taking Mark’s fault finding course, and have other inexpensive hairsprings to practise with. I also got some vintage tools I’d love to use. Until now for me levellers were only the Oliver Cromwell people, but ebay never ceases to surprise...
I could pass the first stages of correcting the coil, with two tweezers. But could not find a use for the vintage tools. Could you help me to figure it out?
Picture 1 is the bent hairspring
picture 2 and 3 the box of tas levellers
picture 4 is the hairspring suffering under my tweezers now
picture 5 shows the tip of the tools
picture 6: from De Carle. Would this be the purpose of the levellers? The overcoil?
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!
GLAD TO BE HERE NEED SOME EDUCATED HELP ON A ETERNA MILITARY THE SERIAL NUMBER DATES THE WATCH 1942.THE MOVEMENT LOOKS ALMOST LIKE A 852S BUT FROM WHAT I HAVE READ THE 850,852 AND THE 852S WERE ALL 15 JEWEL.MY WATCH HAS A POLISHED SURFACE 17 JEWEL CENTER SWEEP WITH SLIGHT VISUAL DIFFERENCES FROM THE 852S .NOW I DID READ THAT ETERNA MADE ETA'S 853 THROUGH 859 AND THERE IS NO DOCUMENTATION ON ANY OF THOSE.AND THE LAST THING IS THE HOUR HAND HAS 2 DOTS FROM WHAT I HAVE READ THEY COULD HAVE BEEN USED AS A PILOT WATCH .I HAVE RESEARCHED THIS FOR A LONG TIME AND HAVE NOT SEEN ANOTHER ONE FROM ETERNA OR ANY DOCUMENTATION ANY HELP WOULD BE GREAT THANK YOU AND GLAD TO BE HERE.
Hi The train wheels are all free running, does the pallet (fork) snap backwards and forwards cleanly when moved, without the balance in , If the action is sharp and crisp the fault lies within the balance area, Is it in beat is balance spring fouling the cock, is the spring concentric, is impulse pin loose , Pallet stones in good shape and not loose, pallet stones locking and un locking ok these are but a few pointers to check before trearing it to pieces again. Doubtless other members will have other actions for you to look at.
Here are a couple of other images of the Seiko and yesterday's Timex.
The only issue with the otherwise excellent Seiko is that some ham-fisted baboon (not me), has attempted to open the back with a crowbar. I can't decide if the Seiko is from 2004 or 2014, but I suspect 2004 from the styling.
I have spotted a couple of Pulsar models with the 7N32 caliber from 2004, and even a couple of Seikos from 2014, so in fact it could be either.
