Pallet cock

Question

Hi

I have just started my first rebuild.

I'm hoping to get help.

I'm doing my first rebuild and i've come to the escape wheel and the pallet (the anchor thing with 2 jewels that interacts with escape wheel)

Do they just have to be placed on the jewel? I can see no hole within the jewel to accept the escape wheel or pallet.

It just seems very loose.

Is this correct or have i made another mistake

Thought i would ask before screwing down the pallet cock.

cheers

Huh... Very odd that a pivot jewel would have no hole for the pivot. Can you provide a picture of the situation? Could it be a capped jewel but with hole jewel missing?

I think i've explained wrong,There's a hole with a jewel at the bottom of each hole.The pallet  and escape wheel both fit in the hole. but there no hole, In the jewel itself? So the escape wheel and pallet are loose fitting into there holes.

God i hope i've explained that better

apologies

Have you looked at any YT vids of how a watch works? Sorry I don't have a link handy but there are a bunch, some of tge old ones from Hamilton and Elgin/ Waltham are superb, very clearly showing the function of each part with animation and everything.

If you can't see the hole you are not using a loupe. 

Then if you see the hole, but the wheel or pallet fork fits loosely as in never finding its place , then the pivot has been snapped.

See the two purple hole? the jewel holes? The escape wheel axle or arbour goes in to 1 hole. and pallet? or fork? axle arbour goes in other.?

The teeth intermesh escape moves fork or pallet which then in turn moves balance..

But both escape and fork are loose.

If what I am seeing is what I think I am seeing, I can see a hole for the pallet fork with an intact jewel. Again, it appears to me that the jewel for the escape wheel is absent without leave.  I do hope I am wrong for your sake.

Huh that would make it a very unusually shaped pallet. Can you photograph that part for us too?

Yes. But the pallets would line up with the view holes in green and I can't see anywhere else the escape wheel would go.

That's why I think the escape jewel is missing.  It should be in the hole circled by the left green circle.

That'd be too close to the pallet and the 4th wheel wouldn't reach it.

Then I see no obvious place for the escape wheel in the plate.

The beauty with escapements is the fact there has been so many different solutions throughout time, take for example the escapement in a pin-lever, sometimes you have them setup like a super duper co-axial speed racer.
So in this case one really can't tell what it is or how it is configured until he posts Pictures of the complete movement, before strip  or at least Pictures of the escape Wheel and fork.

    • The movement indicates 21.    I count 21.  4 - balance staff 1 - impulse 2 - pallet fork 2 - pallet 2 - escape wheel 1 - second wheel 1 - third wheel 2 - intermediate wheel 6 - reversing wheels All accounted for.    Waiting on new Timegrapher to arrive. Update will be forthcoming once it arrives.   
    • Not exclusively, no, but this was one of their major production sites until 1993. If the watch says Great Britain, or made in Scotland or Made in the UK, or UK Time Corporation, then it was made by UK Time Corporation (a division of US Time Corporation, the parent company of Timex) who set up in Dundee in the late 1950s, and also produced other items (the Sinclair ZX and Spectrum computers for example) at their Dundee site. During this time period, Timex also produced or used dials, mechanisms and so forth, made in France, Germany, England and even occasionally Switzerland. The majority of Timex watches for the European market were made in Dundee, but not all. https://en.wikipedia.org/wiki/Timex_Group https://en.wikipedia.org/wiki/Timex_strike Nowadays, like most volume producers, they manufacture mainly in the far east/China.
    • I figured it out. The point is to unscrew the crown and keep it in 0 position when pushing on the farthest/southern spot on the lever from the stem (close to the letter "p" in "push". Notice that the image above is when crown in position 2. 
    • Chemical recation between markers and dial? Is it a plated dial? Send an email to Zenith and tell them that you are a long term customer but are dissapointed; can you help? etc.
    • The other calendar. A Raketa, technically I'm younger whilst wearing this A tricky one to take a pic of as the dial is quite reflective.
