    Strange timegrapher reading-what sort of skullduggery is this?

    Hello, I'm working on a French FE 3611 movement from a 1970's sort of diver watch. Everything cleaned and oiled, demagnetized and all. It looks like it runs fine, but when I put it on the timing machine, the reading makes no sense. It still looks pretty structured, but it is not at all a...

    Swiss PW moon phase Pocket watch - How to get the moon phase going?

    Well, the minute wheel does not want to come off somehow, so I left it on for cleaning. I'll see if I can carefully remove it with the staking tool...

    Swiss PW moon phase Pocket watch - How to get the moon phase going?

    Hi, I have been working on this huge pocket watch with a moon phase and day/date subdials. Now, the hands for the day, the date and the moonphase are supposed to be propelled by the minute wheel in the center. However, this does not have quite enough friction to move the other wheels. It stops...

    Mechanical WW What happens if I put in a shorter mainspring?

    Yes, I noticed that too... There seems to be no way the little star for the date is propelled by anything except the setting mechanism. Juging by the wearmarks behind it, the previous owners must have been advancing the months avidly for a long time. I don't see how the watch itself would...

    Mechanical WW What happens if I put in a shorter mainspring?

    The watch does run with the old blue mainspring, but the amplitude is not always too wide. And I'm thinking it has all these complications to push, so it may need the extra power. Some photos: If that turns out too small, there are more pics here...

    Mechanical WW What happens if I put in a shorter mainspring?

    Hi, I'm working on this ridicilously large moon phase full calendar pocket watch. The mainspring is blue and pretty much set after having been coiled up for a dozens of years and I'd like to replace it. The mainspring specs are: height: 2.50 mm thick: 0.20 mm length: 770 mm barrel: 21 mm...

    Remove Rusted Movement from case.

    I've had similar experience with a dive watch. Soaked it in weapons cleaning fine oil over night, then cleaned in zippo lighter fluid. All the rubber gaskets do swell up from the oil, but they were probably faulty anyway. I have also used penetrating releasing oil with success.

    Tricks for putting on second hands on PW

    Rodico on pegwood for me too. I sometimes use brass tweezers as to not damage soft gold plated hands. At Rolex they use teflon coated tweezers, I understand these are also used by people who deal with fishing hooks (?)

    What is Moebius 921/2 used for?

    Hello, I've recently picked up a batch of watch oils at a clock fair. Among the bottles there is one with Moebius 921/2 in a metal container with a light blue color. I use 941 on pallet jewels, 921 seems pretty close in numbering so maybe it has a similar use? I have a suspicion this batch may...
