have a look here - https://heritage1854.com  for more Info on movements.

black seconds hand...no problem I can list under my seller id.

Timex used a small brass wedge pin to keep the end of the hair spring in place.  Is that missing?

 

JerseyMo no the wedge is  not missing. I was looking for a confirmation of design. How is the spring attached to the adjustor? It reads as if the spring is kept lets say in a hole in the adjustor and just the spring tension keeps it there.

List here on this forum or Ebay using your seller id?  thanks Bob

Alright got home after work and got to work. Removed spring wedge and balance wheel. There was a hole through the top plate where the back end of the wedge could be seen. Using a small screwdriver as a pry bar against the side of the hole the wedge came out. 

The bearings and bearing pivots look good. I did sharpen a toothpick and dipping into alcohol cleaned the bearings.

The balance wheel and hairspring got rinsed three times in solvent. The spring definately looks cleaner.

I ordered three precision oilers which might help for oiling the bearings. When the time comes to peg the hair spring a tiny pushing bar with an opening to receive the end of the wedge would be nice ensuring no slipping off the peg while inserting. 

Will review with our lead model shop friend.20220401_172720_copy_747x1328.thumb.jpg.d28934465876f8938758c807669e99ca.jpg

Keep us posted on the result

 

Watchweasol one thing I have learned is to not use aerosol contact cleaner with lubricant. Having oil everywhere does not help with the battle.

Very true lubrication needs to be put where its needed and only in controlled amounts. Starting with a Timex is a steep learning curve because of their construction, so well done for getting it back together there are many who would not attempt it in the first place

There are two things that I don't understand.

Firstly, why did you use contact cleaner on a mechanical watch? Contact cleaner is only used on Timex Electric/Electronic watches. 

Secondly, contact cleaner may appear oily but it evaporates eventually. After all, you wouldn't want oil on an electrical contact to catch fire.

HectorLooi, I restore, collect, and flip antique/vintage audio vintage hifi gear. There is contact cleaner for on/off style switches and there is contact cleaner with lubrication for sliding resistive type switches (potentiometers). Thought process was the cleaner/lubrication is in a solvent based aerosol spray and would penetrate and get to places that is not accessible without teardown. I just expanded my interest in mechanical watches couple months back. What I thought was an easy way out to lubricate a watch has gone out the window. Bad Idea!

Hi we are back to the point where the spring needs to be made longer. Is there any excess balance spring protruding from the back of the pinning point if so by slackening the wedge and pushing the spring in  it will make it longer and effectivly slow the watch down. Making the spring longer in the round will also put it off beat so that will need to be adjusted, with out some method of deteting the beat error ie Timegapher or the like it will be difficult, a matter of trial and error which is time consuming.

Its a possibility have you not done that already ?.  Have you chesked that when the coils are vibrating that they do dot touch and the spring vibrates between the sides of the regulator and does not hang on to one side or th other.

no I do not have a demagnetizer. I just started playing with the Timex's a couple months ago. I just checked a demagnetizer can be had on Amazon for $12 or so. 

You said " Have you checked that when the coils are vibrating that they do not not touch"......so watching the hair spring while the balance wheel oscillates the coils should not touch? 

You said " and the spring vibrates between the sides of the regulator and does not hang on to one side or the other"

is this observing the spring within the slot in the adjustor which the spring runs through?  The sides of the regulator is the sides of the slot cut into the regulator which the spring runs through? While observing the balance wheel oscillating the spring within the slot in the adjustor should touch one side of the slot during half of the cycle and then touch the other side of the slot during the other half of the cycle??

the Timex M24 service manual states that the hairspring should be in light contact of the inside edge of the slot in the adjustor through out the entire cycle of the balnce wheel.

thanks Jersey....may hold off until I can determine why the watch is running fast.

Under normal circumstances  a watch spring beats within the regulator, Timex were a law unto  them selves so if the manual states a light touch on the inner side so be it.  When the coils beat they should be free with no interfearance if the coils are touching  and not flat  it has an effect on the spring  which could cause your problem

Okay got home after work and inspected the hair spring closely and lo behold the two most outer coils were touching. So I stopped the balance wheel and oh so very carefully separated the two coils and they stayed apart. 

Have been monitoring the watch and I believe the watch is not running fast. Will continue to monitor and check in the morning. But am confident that it is not because I would note after a couple hours that it would jump a minute and it doesn't appear to do that now. Very excited thanks watchweasol for the insight on inspecting the hair spring after installation .

Could it be that your regulator is stuck? Try putting a drop of oil where the regulator is riveted to the plate and work the regulator left and right.

HectorLooi I think we got it. Thanks

    • Welcome to the forum, enjoy.
    • Just picked this up earlier today. This find just about epitomizes vintage watch collecting for me and what really keeps me going. Hit 2 antique malls today and saw a couple of pieces at the first one but just nothing that I needed. At the second one saw a Accutron 218 but it was 20 minutes behind the actual time. These "malls" have numerous booths of a variety of sellers who likely go in once or twice a week. Considering that that watch should be within a couple of seconds a month, I figured it hadn't been phased so passed on that for now knowing it would need work to run correctly and the price tag. Then I found this Excelle in a display case. I never heard of the brand, but in was an auto and had a little heft. It turned out to be 40mm lug to lug, 35.3mm case width, and 12.3 mm thick. On the spiedel once size fits most flex band. At $10.80US with tax I immediately pulled the trigger with nothing to lose. Before pictures: I spent a nice 30 minutes taking it out of the case and running that through the ultra sonic replacing the crystal and gasket and recasing, but spent five minutes first getting it running close on the timegrapher. Had a new crystal already in stock. I probably could have sanbed and polished the old one, but for $3 there is nothing like a new acrylic that makes a watch pop, in my opinion. The caseback gasket was hardened and just glad it wasn't tar. Changed that as well. Here is the after Pic on a temp black strap while I decide on a leather or steel bracelet. An added bonus was doing some research and finding out the Elgin connection and the movement is a PUW 1563T which is German I am pretty sure and probably why it doesn't say Swiss made on the dial. This movement is supposed to have a hack feature and quickset date by pushing the crown. But neither of those complications seem to be working. Not sure if the stem is cut too short because there is no gap for the crown to move. Either way at some point will need to be serviced and check the keyless works to find out what is going on with the quickset and hack of the sweep second hand.
    • On the link that I posted, one of the watches has no crown and another has a crown that is not square to the case. Does a broken crown signify that the movement may be quite corroded, hence the stem has broken, and does the bent crown simply signify that the stem is bent? Unfortunately as the seller has a bid on the items, he is now reticent to prise the casebacks off in case he damages something. The seller did reply with this email though. Hi again Michael - brief descriptions; Oris x 2, dials and hands ok and they set ok and one I just wound and it has been running for a few of minutes as I write this response. Rocar, dial ok no crown. No name dial no good and can't pull crown out to set. Roma dial and hands ok, I think it is pin pallet movement. Unicorn, good dial and hands and plexiglass ok for age. All cases and plexiglasses show wear except as mentioned. I have no idea what movements are fitted or condition so please if you do consider bidding, please do so accordingly as I don't like to disappoint my customers - regards and thanks again for your interest - Jim
    • The incomplete Vertex DD is a new project to sort out.  The Seiko gen 1, is my favourite watch to wear and is my daily.      
    • To be fair it was a beautiful 'bumper'.  But, there was some loose parts in the case.  Perhaps 'pig' was a bit excessive 😄.
