  1. All other things appearing equal in the listed dimensions, you could find that the arbor diameter is different between these 2 springs
  2. Either “Sir” or “Madam” should be fine
  3. Looks like it’s based on and shares many parts with a Peseux 7020, but is 11.5 lignes instead of 10.5 http://cgi.julesborel.com/cgi-bin/matcgi2?ref=LP_78
  4. Try searching for “6498 dial” on eBay. Here’s an example https://www.ebay.com/itm/Parnis-35mm-Black-White-Dial-watch-kit-for-Seagull-st36-eta-6498-movement-watch/262678727500?hash=item3d28df4b4c:m:mvjGZtyvYwAeFDB_anobYlg
  5. @AlexeiJ1There are tools out there that allow a balance staff to be punched out without removing the hub. I’ve never tried one, but I don’t understand how they overcome the basic challenge. When the staff is fitted, it is pushed in so the balance arm sits against the hub. The diameter it sits upon protrudes ever so slightly higher than the arm, so tapping this with a domed punch causes it to spread out slightly. The flat punch sets this so the staff grips the arm like a rivet. When replacing the staff, if the hub has been turned away the staff can be pushed out so the riveted part doesn’t have to pass through the hole in the balance arm. Otherwise you have to push the staff out the other way and risk damaging the balance arm hole. Clearly a new balance complete is not really an option here! @jdrichardIf only I had the time to perfect that art! Sadly I have to find time to go to work too!
  6. A friend asked me to take a look at a pocket watch recently which stayed in hand setting mode even with the crown pushed in. I assumed a broken yoke spring... but actually no harm done, other than dried up really sticky oil everywhere! Goodness knows when this movement was last serviced, but certainly not in the last 20 years I would guess. I didn't take any photos before disassembly as it wasn't really easy to see what the problem was just by looking. But this picture of the train bridge shows the centre wheel stuck in its bush with crusty oil Unfortunately, there are also a few fingerprints and corrosion spots on the plates, which I couldn't remove during cleaning. I found a couple of other interesting things during the disassembly. The bridle on the mainspring has a little Omega symbol stamped on it. Sadly, I don't think the spring is correct for the watch - it should be a double brace and hole spring, but only has the lugs to fit in the barrel slots, not the hole. It may also be a little short, but on the basis that it must have worked once, I thought I'd clean it up and give it a whirl. More problematic was that the balance staff was missing a little off one of the pivots - enough that the pivot wouldn't reach the end-stone, so I figured that had to go. Of course, not easy to track down a replacement balance staff for a 103 year old watch, but eBay was my friend on this occasion. New staff on the right, and what a beautiful blued Breguet hairspring Set in the lathe ready to turn off the hub Hub removed so I can punch out the staff Old staff out Punches at the ready to rivet the new staff in to place - one domed to spread the rivet and one flat to set it. The staff was a little loose in the balance arm, but it riveted down OK. Finally pushing the roller table back into place And checking the poise. It was a little out, but there was some dirt in a couple of the screw head slots and removing that seemed to do the trick. Hairspring back on and ready to go Keyless works back together and now moving freely Barrel bridge on Train wheels and jewels all cleaned Train in place One of the lovely things about old watches is the serial number popping up everywhere. It had been scratched inside the barrel and I didn't take a photo of that. but here is the marking on the back of the pallet cock. and on the back of the balance cock Quick wind and off she goes The case is stamped EWCCo (English Watch Case Co) and is hallmarked for 1927 so is therefore just over 10 years younger than the movement. It also has some case screw marks inside which don't line up with the Omega movement so obviously a later marriage. And just for kicks, alongside my Omega PW from the same year. I think I know which one John will want me to give back to him and anyway I'm still in love with those Omega hands!
  7. Yes indeed - have come across lignes of course, but never thought that they would be divided into 12ths and called douziemes!
  8. Thanks Nickelsilver. Will give them a good polish with some fine wire wool at some point
  9. Now to go with the caliper competition, I genuinely don’t know what this is for - my best guess is holding watch hands whilst opening up the holes, but it seems a bit agricultural for that. I’ve seen them on eBay a few times but never with a description of what it’s for. This one needs a bit of a clean up but doubtless one of you will know what I can use it for once I’ve done that...
  10. I was given some old tools recently. Just for amusement, I thought I’d share a picture of this, now I’ve cleaned it up and worked out what the calibration is. I was going to just tell you all the answer but let’s see if anyone can guess. The photo doesn’t quite show it clearly but the scale is marked 6, 12, 18, etc. Full travel is 72 which is about 13.5mm. By the way the prize is bragging rights not the calipers!
  11. In theory this should be a drop in replacement, but... 1. Make sure you don’t get confused between shockproof and non shockproof variants... they have different balance staff lengths 2. I have bought supposed balances complete where the terminal curve on the hairspring wasn’t properly formed. However, I would agree this is your best option
  12. Not many clues in the usual places on this question, funny enough though, I note that Watchguy, Gleave and Cousins all have the same hand made annotation on their parts sheets! Most likely they are interchangeable and the 2556.1 is just an upgraded version. By the way, if your German is up to scratch, this might interest you. If not, then just the oiling charts might be of use http://forum.watch.ru/attachment.php?attachmentid=952077&d=1426676161
  13. As you say, harvesting is a good option, but Cousins does sell these https://www.cousinsuk.com/product/hairspring-collets-pins-wristwatch?code=S37391
  14. John senior has them for £1.75 http://www.obsoletewatchandclockparts.com/Jewels-and-Bushes.htm
  15. I too bought moebius 8000 when I started out, thinking it was the cheaper option and did the same job as 9010. I bought 4 bottles and I’ve barely dented the first one, but I can tell you its expiry date is Feb 2015... so they’ve been putting dates on it for more than a couple of years. I recently (some time in the last 6 months) bought some 9010. This has a much longer shelf life and it expires in October 2023. Personally, I would return the 8000 and buy some 9010 from somewhere that has a high stock turnover. However, unless you turn out to be a master watchmaker in a very short space of time it’s unlikely you’ll notice any difference :-)
