  1. I agree it's probably just the thickness of the case although there may be a method to adjust the sensitivity. I've done some Seiko 7002's that had pretty thick cases and found that taking the case back off during testing was an acceptable workaround.
  2. Cousins has a pretty wide assortment of Drive In style pushers. I'd try the Far East style first as they seem to be priced better. It's helpful if you know precisely the diameter of the hole though. I'd suggest replacing both to ensure a matched pair.
  3. pocket watch pallet fork

    I'd check the pallet stones. If one is too long (perhaps loose) it won't release the tooth of the escape wheel. Actually the other American pocket watches had adjustable banking pins. I'm not sure exactly how it will come into play (other than affecting amplitude) but perhaps the pins are way out of alignment. Hopefully someone more knowledgeable will chime in here.
  4. Missing chronograph reset pusher. Gallet

    Hello Luca, That is a very fetching timepiece! If the pusher is a common round-head waterproof pusher then you probably can find an aftermarket replacement that will fit from Cousins; their website is pretty good about giving you the dimensions of the piece to help you out. I think finding an original is unlikely though.
  5. Very small collection

    Very nice. I'm partial to the Submariner. In keeping with the theme, watchmakers whose name ends with "ex", I would suggest adding a vintage Timex to the rotation.
  6. Lew & Me

    Very sorry to hear you lost Crumble today. :o( I had a cat, Noel, who I got on Christmas when I was ten and who I lost when I was twenty eight. It's strange how they start out younger than you and end older. She never looked a day over 2 though. I still think of her. They're always good for a laugh you know.
  7. Aren't some of these old crystals fitted by heating the bezel? Maybe I dreamed it up, but I thought pocket watches with mineral crystal glasses required the bezel to be heated in order to expand the opening to accept the crystal. I haven't done many pocket watches so forgive me if I'm leading us astray here.
  8. For the person that has everything

    Yeah, I saw that the other day... A very interesting mechanism to be sure but it made me think of the line from Jurassic Park, "Yes, but your scientists were so preoccupied with whether or not they could that they didn't stop to think if they should."
  9. Valjoux 72 help

    Those are the frictions springs for the Chronograph Runner (8000) and Hour Recording Runner (8600) and Conveyer Wheel (8610). The spring for the Chronograph Runners is longer and is located on the Barrel Bridge: The other two are on the Main Plate (dial side). Following is an image from a Valjoux 71 I worked on- I think the hour recording mechanism is pretty much the same assembly as the Valjoux 72:
  10. Crown knurling

    Yes, that's a good point and admittedly I didn't really think a lot about the lathe bearing as in my case this was a one-off. The lathe is the most expensive tool in your kit so best to take my advice with a grain of salt. In my case I didn't need a cross slide to knurl the knob I turned- simply bringing the knurler in contact with the nob while turned on the lathe was enough to cut the coin edge. It took a little less than a minute but it's important to note, I was working with soft brass; here's a pic for reference:
  11. Crown knurling

    Sure, Here's the one I purchased: https://www.ebay.com/itm/Single-Straight-Diagonal-Linear-Knurler-Knurling-Tool-Set-0-5mm-Pitch-Wheel-KIt/192408409882?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 You can also find some with two wheels which will create a cross-hatch pattern.
  12. Crown knurling

    If you have a lathe (I'm assuming you do since you turned the crown) there are very economical knurling tools available on eBay. I just purchased one a few weeks back to put a coin edge on a knob- worked like a charm. The tools are available from China so they can take a few weeks for delivery though. Take a look at Clickspring's YouTube channel for knurling on a lathe. He makes everything look possible.
  13. I can't add much that hasn't already been said but I will drop in my nickel's worth just the same. For starters- that's a great watch and if it has sentimental value I'd certainly save the money necessary for a proper repair. That being said (here comes the bad part) if a trained technician already estimated between $3k and $7k then is sounds like the movement has extensive damage. No one can make that assessment without seeing the inside though so I'm anxiously awaiting any pics you may have to offer. Judging by the description "the printing on the face has been burned off and it also has water damage" it sounds like the piece survived a house fire- that's what would be called "salvaged" in the auto industry. Could be expensive for sure. A bit about Rolex parts- they're difficult to get a hold of as Rolex only sells to certified technicians. You can find parts and even whole movements on eBay however but they'll cost a pretty penny. Regarding tools- I got into watch repair because I figured I could assemble an Omega Speedmaster from parts for a lesser price than purchasing a new one. This turned out to be true- if I exclude the cost of the tools I purchased. At the very least you'll need a loupe, a set of screwdrivers, and good (Dumont) tweezers. Rolex requires some specialty tools as well such as a Microstella wrench for timing adjustments and caseback dies (although if the caseback isn't too tight a wad of sticky duct tape just might work). As for performing the repair- De Carle's books are fantastic for getting your feet wet. A stereo microscope is a godsend if you can beg, borrow, or cheat one. You will lose parts so it's best to practice with a cheap movement so that you can get the feel down when using tweezers (I would suggest a lower priced new movement- there are many that come from China and some are clones of Swiss movements, all are good for practice). Lastly good luck!
  14. Cool! Nice paperweights too.
  15. Zenith 136

    I think eBay would probably be the best bet since it's a pretty old movement. You could try Cousins and Otto Frei or Scotchwatch as well. The 136 is a Martel movement which Universal Geneve also used for their chronographs- so I would image a UG balance would fit in a pinch. You will need to determine which UG chronograph calibre (281, 283, 285, etc.) is the same as the Zenith 136 though. Also important to make sure you get one with the right staff (Inca/non-Inca).
