Hi all,

  It's been a while since I posted anything here but tonight I was working on a watch and I thought there might be some interest in looking at it. The customer said the second hand would move but the hour and minute hands wouldn't. Usually that means the minute wheel assembly has became worn however today that part had became seized onto the center tube. Anyway I took a picture of what is under the dial of a 218 in case there was any interest. Notice the three springs that are laying about. The first time I tried working on one of these I lost every one of those things and maybe some of the other parts as well. I told my wife it was like trying to bait a mouse trap after you had already cocked it. Anyway I have this watch going now and here's what it looked like before.

Very nice.  I've done a couple of 218 movements as well and found the calendar springs to be difficult to set; if I remember correctly Bulova changed the design slightly between the 2181 and 218D movements as one was much easier to reassemble without the springs pinging away.

They're wonderfully engineered timepieces that keep impeccable time.

Hi,

   Since RYMoeller mentioned it they did change the both of the spring for the date. I am posting some pictures I took especially today just to show how the date goes back together. I took pictures of two springs. The date jumper spring was later changed so that the little hook was removed and you could install it after the date ring late was in place. The spring could still get away but was much easier. The bigger date spring was changer so that it could be installed onto the main plate instead of the date ring plate. As you can maybe tell in the pictures with this model you place the date jumper spring then try to mount the date ring without either spring moving. Once you get the date ring plate positioned you then have to adjust the date spring so that it is positioned properly. That's what I meant by baiting a cocked mouse trap.

Hi again,

  You may notice that once the spring for the date jumper is in place the date ring moves. I just let it and center it up after I have the date ring guard in position with one screw loosely in place. This means there is less tension on the spring and it is less likely to run off. My technique anyway.

    • Hmmm. We’ve all had that happen. The movement isn’t securely attached to the dial and when the movement moves outward at all, the dial pulls the hands off. You will have to remove the movement/dial once you get the stem out. Then you can reattach the hands.
      Look into that oblong hole to the right side of the stem in your photo. Watch inside it when you pull the stem in and out and you should see a tiny lever with a really tiny hole in it moving back and forth. There even may be an arrow on the movement pointing toward that hole. When you see the lever plainly and see the hole in it, put a toothpick tip or tiny screwdriver tip and apply a little pressure there. Then the stem should slip right out. That hole sometimes appears when the stem is pulled in the setting position, sometimes in the normal position. That’s why you have to pull the stem in and out to see when it appears. After you get everything out, you can fit the hands back in place, noting the proper position for their placement so they line up properly. Hour hand on an hour marker and minute hand at 12. Seconds should be at 12 when the minute hand is on a minute marker. At least you don’t have the added complication of a date. Good luck. Steve

    • Hi guys, First time watch repairer here. My Tokyobay watch shown in the photo below needed a new battery. So I got the new battery, popped open the back, and popped out the old battery. Unfortunately, somehow while this was going on, I caused the minute hand and the other small hand (not sure it's purpose) to fall off! And I have no idea how to fix this (though very happy to try anything). The inside of this is a Miyota IL45 and I assumed the first thing I'd need to do is get the stem disconnected from the movement. I tried pushing a pin in some of the holes and gently tugging on the crown/stem to get it out. But it didn't work and I have no idea where the release is. So that would be the first step I think... After that, I don't know how to get at the hands to put them back in place. So that's the harder step two. Would very much appreciate any help on this. From what I can tell, this watch doesn't seem to be very repairable. But hoping you guys can guide me!

    • Update: so i cleaned the watch completely and replaced the mainspring with one that i had. Had to anneal the end and bend in over to catch the barrel hook.

      I then examined the jewels and found one badly damaged jewel and two other cracked jewels (fix later). Then i noticed that a tooth on the center wheel was bent completely over. I wedged in a knife and was able to move the tooth back without breaking. Lots of work remaining on this old beast.
