A friend asked me to fix a Timex Indiglo watch that belonged to his recently-deceased father.  Were it not for the sentiment, it would not be worth it.

The movement appears to be dead, but that is not a problem because I have several that I recently bought for $2 apiece.

However, to maintain the same dial, I need to switch dials from the bad movement to the good movement.

Before I dive in, I wanted to see if this were even possible.  I am sure @JerseyMowill have an answer for me!!

My fear is that the indiglo electronics is integrated with the dial.

My understanding is that the dial is coated with a compound of zinc sulfide mixed with copper, a substance which becomes luminescent when an electrical charge is applied.  so there are no electronic on the dial itself.  And to add I've never swapped a movement in on of these. So that is about all I can add.

I have repaired one of these time ago. I learned that Timex never made available replacement stems and not even the entire module, just the first would have saved me quite some effort. Evidently a deliberate choice to sell more new watches. I whish the consumers knew about this kind of things and avoid the brand (sometime a no brand) entirely.

Yeah on further inspection, it is clear that the module is not intended to come apart.  It is fastened together by melted plastic pins.

I was able to bring this movement alive using my demagnitizer to spin up the rotor and train.  That seemed to loosen things up.  The watch is assembled...will monitor.

    • Yes, the specific old tools do exist, but may be having one is not needed as they are not cheap, and also You will be able to do without it well enough. My advice will be to use regular depthing tool and adjust it for the exact distance between pallet fork and escape wheel bearings from the watch. Then remove the shellac from the pallet that now doesn't pass the ew teeth and move this pallet in. Then put the pallet fork and ew on the depthing tool and check how they lock. They should not lock when the pallet is in, but You will little by little move the pallet out and locking will appear. Then move just an idea out for reliable work and apply shellac, then check if things are still the same. You have to observe where the teeth fall on the pallets - it must be just a little below the edge between impulse and rest planes. Then You must check how everything behaves in the movement This Potence tool is so ingenious, but actually, the traditional way to do the things is much more simple. Arrange the parts not on the pillar plate, but on the cover plate. Only the central wheel will remain on the pillar plate, secured by the cannon pinion.
    • There is a tool that was made for setting up and adjusting escapements of full plate watches.  There were two styles, the picture below shows both of them.  The lower tool held a movement plate and the vertical pointed rods were adjusted to hold the unsupported pivots of the lever and escape wheel.  There was also a version of this tool that had 3 adjustable safety centres so that the balance pivot could be supported by the tool :  The other version I’m aware of is the Boynton’s Escapement Matching and Examining Tool came as a set of two or three clamps that gripped the watch plate and held the safety centres for the pivots : These do turn up on eBay from time to time.  For some escapement work, you can set up the parts in a regular depthing tool, with the centres set according to the distance between the corresponding pivot holes on the movement.  I hope this helps, Mark
    • Once you are aware of the problem, you can adjust as necessary. I have a couple of the Omega 10xx, and they are not my favourites. They seem a bit flimsy and not as solid as previous generation Omega. But I think that's true of a lot of movements from the 70-80s. For me, the 50-60s is the peak in watch movements, where the design criteria was quality, not saving the last penny.
    • Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers
