  1. When fitting new stems to watches I use these tools :- Digital calipers, Fine grade diamond lap Wire cutter Pin vice Now for fitting. (1) Hold the stem in the pin vice and screw on the crown tightly by hand. (2) With the movement fitted correctly in the case, insert the stem until it locks in place. Now measure the gap between the case and the underside of the stem. In this case it is 2.16mm. (3) Subtract 0.2mm from this size and this will give the amount to remove from the stem. In this case it will be 1.96mm which will give 0.2mm clearance below the crown when fitted to the watch. (4) Now remove the crown from the stem and hold the stem very tightly in the pin vice, then place the pin vice and stem between the jaws of the digital calipers then zero the calipers. (5) Remove the calipers and without touching the zero button set them to minus 1.96mm. THEN RE-ZERO THE CALIPERS AT THIS LENGTH The wire cutters are now used cut off the excess thread leaving a small amount to be filed to the exact length. (6) All that is required now is to dress the stem with the diamond lap a little at a time until the calipers read zero. (7) Finally screw the crown on tightly and it should be ready to fit to the watch without further adjustment. I find that this method cuts down on trial and error. FOR SCREW DOWN CROWNS. A) Screw down the crown tightly onto the case without the stem and measure the distance nbetween the bottom of the crown and the case. B ) Screw the new stem tightly into the crown, then insert into the watch until it engages and locks into the movement. C) Press the crown down firmly as far as it will go and hold it there. D) Using the vernier callipers, measure the distance between the bottom of the crown and the case. E) Subtract the size determined in (D) from the size measured in (A) then subtract a further 0.15mm from this size. This is the amount to shorten the stem by. This should allow the crown to screw full home without compressing the stem too tightly between the movement and the inside of the crown. F) Cut the stem leaving it slightly longer than the size determined in (E), and dress down to size using the diamond lap and vernier callipers as described in the original post. G) Screw the crown onto the shortened stem and check fit and function, before using a tiny spot of Loctite 221 to secure. Click here to view the article

  2. I picked up this non-running Hamilton with a Swiss ESA 9158 electronic movement on the bay for $25 . It has a screw down crown , and when it arrived I could see that a bezel was missing . I searched the internet to see if I could find a picture of what the old bezel looked like , with no luck . The rubber watchband was salty , dirty , and twisted into the shape it was stored in . When I opened it up I was presented with a movement that was swimming in oil ,...you could almost pour the oil out . I had to clean my tools and work surface when I got it out . I removed the dial , hands , and dial ring and cleaned them up hoping that the finish on the dial and hands wasn't ruined . I was able to find a complete working movement for $20 . Fortunately, after cleaning up the case , dial , hands , and watchband , everything looked good enough to re-use with no apparent damage done by the oil soaked parts . I reassembled the watch with the donor movement and it was off and running . I checked my stash of parts to see if I happened to have an old bezel that would fit the case . I pulled out a Seiko bezel that I had changed out on a Seiko 6138-0011 UFO / Yachtsman I have and it fit . I used a piece of brass wire of the right diameter to form a bezel spring to fit between the bezel and case , as each part had a slot where a ring would fit . Luckily all the parts fit very well . The bezel fits firmly and turns as it should . The Seiko UFO .... And The Hamilton Electronic...I have since , reset the day and date...

  3. Try mount the watch with the stem pointing to the microphone first. There is also a software for frequency filtration. Basicly makes the soundcard to a preamp. Check Your soundcard settings! Increase input volume or switch boost function on if available.

  4. This is the 14k gold Model 877 with 15 jewels and originally sold for $110. Heres how it arrived - yes thats lead solder on the bottom right... sure you've see it all before but for me, first time but I couldn't let that stop me buying it. I had a gold smith clean up the case and remove the lugs from another case and then went and saw a laser welder who attached the replacement lugs, I did the dial swap and case polish, then sewed up the ribbon band and the end result its currently 87 years old and hopefully will last another 87 years.

  6. It won't work! Me wife steals my Lord Elgins all the time. Rarely does she wear a ladies deco period watch and she's a deco nut, she loves them but they are too small for everyday wear. That's a bonus for me as I restore them and don't have to worry about day to day wear. Here's the model 103 Madame Premet from the Parisienne line, again, restored from bare cases and the matching ribbons and clasps is how they would have been in store when they went on sale in 1928

  7. I know he does. Its as I've said many units such as complete barrels are now obsolete.

  8. The mainspring shouldn't rub the barrel cap, if it is doing that then the spring is to high. Rub marks is a sure sign it needs replacing.

  9. Your right it is secured by a pin. I would take it apart. Going back to the chain be careful when removing the old rivet that you don't split the chain or bend it.
