Okay I apologize for veering off topic like this although this endeavor could work well with a classic Timex movement I think... ?

I may order a few more cases and see if this is the case... no, pun intended!

Here we go, I ordered up the mineral glass exhibition back form Otto Frei and a nice leather strap. I intended to use these to hold a Helbros Swiss movement I had with a rotted out diver type case. The size seemed right, but, well, I'll get to that. It looks great! A little spit and polish on the dial and in it went.

Now... here's the problem...
The movement is a touch too thick. When I use the spacer that came with the case the seconds hand staff hits the top glass and stops all motion. When I leave the spacer out it rattles and seems to hit the back with the rotor.

I am planning on slicing a bit off the top edge of the spacer (it's plastic) and using the sliced off bit as a spacer on the top of the dial. Does this make sense or sound good? If not, how bout some advice? I won't pick up a thing 'til I hear back form the braintrust!

Sincerely!

Yes, cutting the spacer into two pieces might work well. All you have to do is make sure you do a neat job making the cut. If for some reason you mess up the smaller piece that you are going to cut off of the top of the spacer, then maybe you could make a spacer to use above the dial from a piece of wire or one of those large diameter plastic or fiber washers that are used to make bath tub faucet fixtures water tight. You can find these washers at most plumbing supply stores and if you do look for such a washer to use, then bring the watch case with you so you can check the fit in the store before purchasing the washer.

The only other alternatives I can see would be to replace the case's crystal with one that is higher and will provide more clearance for the second hand post. Or, you might have to remove the second hand and the gear/pivot that drives it...obviously, this would be the last thing you would want to do...

Good luck with the project.

Hey Charlie,

Sounds like you need to make the spacer a little less thick (like you said). I would take the spacer and sand it down on my sharpening stone a little at a time until I got a good fit. Lay it flat and slide it back and forth until it fits.
