Hi there,

I'm new in watch making/cleaning and I have that problem: How to measure the Hand Winding if I didn't have one? It's old GP watch with watch mechanism measure 25,68mm. NO 410770.

Any one have knowledge how to do that or where to find that on internet?

Cheers

Hi  From what I can make out from the picture its missing its Male half of the winding stem with crown, Is that the problem ? If so the reference made by Klassiker points you to Ranfft's web site which will give you the stem number. From where you get the part will depend on your location.  Ranfft's site will give specifications on a lot of watches so may be useful in the future for you.

Hands are measured in length  from the center  of the hole to the tip in mm. The diameter  of the hole can be determined  easily. Look  on the movement  for maker  and model number.then look up on ranfft website.you will find measurements  there.

      An intro…

      By HorologyHead · Posted

      RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.

      The whole process and the progress are closely observed, it's hand-driven and very controlled. I can't see the "danger", unless you are watching the TV while doing it. As you could have read, and in this quote "wheel" is the balance-wheel.

      AS2063 - hand setting

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark

      Stem broken - can it be rescued?

      By Khan · Posted

      Hi I got a Jaeger LeCoultre K911 movement, where one of the stems was broken. Part no. Should be 401.  Im based in Europe and tried Cousins but its discontinued. They except to get stem in stock for cal. K916 but will that work? Or Is there a way out to join the ends?

      The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem.
