    Thank you for that. Under the balance is a Swiss style cross in a shield and what appears to be P 756. This still means little to me. Any help as to the manufacturer ?

    Well!!! I am impressed. Many thanks for that

Take a closer look at the movement, especially under the balance wheel (use an eyeglass). There should be movement code. By that you can find the real movement manufacturer and the hairspring or balance complete will be easier to trace.

    So, here we are! You are looking for PESEUX 756 balance complete.

    Put on ebay request for that- it might turn up.

    Peseux movements are not produced anymore and you have to wait til so called New Old Stock turns up.

    I forgot to tell you one very important thing- go and shop around for watchmakers. Ask them if they can get (or even have) that particular balance.

    And one more: if you have that old, damaged hairsprig left- take it with you and ask if they can recoil and fix it.

    I'd do that, but unfortunately I'm too far (England).

    Best of luck.

I need to take the movement out of my ladies rotary lb77835 has to come out of the front but not sure how thats done

Don't know why this is posted under a Rolex issue or why you would be taking the movement out of this watch. I would suggest taking the back off if you haven't already.

The movement is connected to the crown, so basically if you're going to take out the movement, you're going to end up breaking the watch.

If you're trying to replace the battery, this can be done without removing the movement. I would suggest bringing it to a jeweler. They can replace the battery for ~$10.

Im in need of two links for the slimline watch braclet

Thank you for contacting FixYa.
You can usually get extra links from JJ/Helbros but for some reason I can not get their website. I would look for a phone # in the manual and call them. They will want the #'s on back of watch.
Best regards. Jewel

At the bottom of this page Click on Repair Service Directory then watches. Please be aware, like any machine John, your vintage watch has wear in it, the gears in the gear train, have the slightest play between the teeth, the main spring and hairspring are not as tight (rigid, springy) as they were when your watch was say, 3-5-10 years old, these factors all contibute to your watches off time as a matter of speaking.

Hi Sir...Thanks. The Hairspring is pretty clean. Thre regulator is now pushed till the slowest setting (-) . But still the watch run fast. Any guidance? :) Alex

If the hairspring is perfectly clean (pretty clean is not good enough), then you have to observe it by using magnification eyeglass. Check out if the coiled parts are touching each other while the balance wheel is in motion. If that happens you need to recoil/repair hairspring and make coiling perfectly even. Also check out if the hairspring is touching balance wheel or coc;k. It must not touch anythining and must expand and retract freely. Coc;k is the bridge on which the hairspring stud and regulator (index) is fitted. When this is sorted but the problem still persists, get back to me again I'll guide you through the next stage of possible solutions.

Watch tick much faster

You have to clean hairspring. Unless the hairspring is spotless, there is no way the watch will keep time. Make sure hairspring coils are even and not touching. Rate me, please.

Case info does not help in dating a watch, A movement serial number helps greatly.

Setting Day/date on Helbros wrist watch

As an extra tip, to advance the date a little faster, you can turn the stem and rotate the hours past midnight and keep going until you pass 2 AM, then you can wind backwards, going past about 8:30 and you will hear a 'click', then you can go past 12 am again and the date will change. This makes it a little quicker to advance the date several days.

Runs Fast

Usually when a watch with a mechanical movement is running fast its is because the adjustment on the hairspring is advanced to far. Since it wasn't running fast to begin with I can assume its because something was knocked loose. It is possible that a tiny drop of oil was on the hairspring and by knocking the watch two coils are stuck together by the oil. (this usually only happens if it has been over oiled by an amature watch repairer) Magnitization is possible but pretty unlikely, unless you play with Big coils of wire that are carrying a LOT of current. Either way, unless you know what you're doing and have the right tools, you are looking at taking it to a Tag repair center. Since a simple tune up can cost about $250, I'd expect to pay $400 to $500 for that one. Welcome to the wonderful world of high end watches.
