Glue TV style acrylic crystal into case?


Recommended Posts

I'm in the late stages of fixing up this TV cased Timex. It has a conventionally circular acrylic crystal, but ground or molded to the TV shape in the center. Luckily it responded well enough to polishing that I don't need to replace it. But this watch came into my possession assembled with the crystal loosely placed into the case, with a thin gasket between its circular flange and the case interior. When the movement is installed, the dial's outer edge presses the crystal slightly into the gasket, but not enough to seal at all. The crystal does not snap into place or fit under any friction; it falls right out when the movement comes out. I assume it's the original, if only because its implausible someone would've ever replaced a weirdo crystal on this $25 watch.

Do you think I should just glue this crystal in with hypo cement? Or maybe try a thicker gasket to put more pressure against it? It only has a snap-on caseback. Sandwiching it in loosely with the gasket doesn't seem like the right solution. Any water resistance at all is a secondary goal to a watch that doesn't fall to pieces when the caseback comes off. And it's staying in my own collection.

Hi Under the circumstances and the fact its stopping in your collection so un likley to receive any hard knocks  use the Cement or a UV curing adheisive.

Thank you, I'll glue it in. Out of curiosity though, you mentioned hard knocks; would the gasket provide some shock resistance I'm not considering? Or do you mean "hard knocks" in the figurative sense, like it will be generally abused in ways I can't predict, submerged in water, etc?

I would imagine you, knowing what it took to fix your watch, would be more protective of it.  You value the time and effort it took and most others would not (present community excepted).

I'd like to see it all together when it's done.

Hard knocks in the figurative sense, in as much as below. Its hopefully not going to live the life a lot of the Timex brand did in the early days, Being a mans working watch.

I came across another example of this Timex model and bought it for a bit more than the first one cost, but it was more complete. Though they're both 1978, the second one's crystal is different. It's much flatter, not domed, and is snapped tightly into the case with the O-ring. This suggests the first watch's crystal isn't the original after all.

I prefer the look & character of the domed one to the flatter one, but may yet switch it out on the one I keep if I can't get it solidly attached (Hypo cement isn't holding well)

Aside: The second specimen's hands were also original and undamaged, and they are not the same as in the catalog photo discussed in my other post. As pictured in the catalog, the hour hand can't clear the 12:00 index without either a taller cannon pinion or contorting all 3 hands way out of shape to make it work. The actual 1978 watch's hour hand is shorter, and doesn't have to pass over the 12 index.

This piece has been floating in and out of my job queue since summer but it's finally all done. I had a second specimen and after chatting with someone I sold a different Timex to, it turns out he was in search of this exact model. I then found a third with an unsalvageable crystal but perfect dial to swap for my own bad dial. So between mine and the one for the other guy I've got 2 in great condition now.

I put mine on a blue faux crocodile strap.

Yes, it does look good.

From time to time, I have seen other TV watches and have passed on them all.   They always reminded me of the 70s, specifically parts I didn't like.  Since your original posting (I can't say why) they now remind of several aspects which I did.

Thanks.

Nice job.

    • I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark
    • That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much. 
    • Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release. 
    • Yes, "Sold out" is difficult to understand. There doesn't seem to be a lot going on. It's been nine months since any new video was published on the Watch Repair Channel. The Level 4 course on watchfix.com has been in progress for what feels like forever (several years!?). Maybe Mark's enterprises aren't doing well or perhaps already so profitable there's nothing much to motivate him for more material. Or, perhaps these days he's more into crochet. The real reason is probably something entirely different but it would be nice/interesting to know. I don't mean to sound gloomy or pessimistic, but I wouldn't be surprised to be met by an HTTP 404. Every day feels like a gift. Speaking of watchfix.com I've been postponing the "Level 5: Servicing Chronograph Watches" course for a very, very long time. Anyway, I just enrolled on it so it's going to be very interesting to see the videos. I must say, IMO there's nothing really that can compete with Mark's courses when it comes to presentation and video quality. It's simply world-class and makes me associate with some really expensive BBC productions.
    • Steel has some funny properties, or at least counterintuitive. The modulus of elasticity is effectively (not exactly, but close enough) the same for steel that is annealed and hardened. What changes is the point of plastic deformation* . If the movement of your spring doesn't pass that, it should work fine. It looks a little thick, I would thin it a bit maybe from the main body out about halfway, maybe 10-20% thinner (not in thickness, along its form). But if it works it works!   *So- if you have two bars of the same steel, one annealed, one at 600 Vickers (general hardness watch arbors might be), clamp them to a table so the same length is hanging out, and put a weight on the ends, they will bend the same amount. But if you continue to add weight, then remove it, at a point the annealed bar won't return to its original straightness. That's the point of plastic deformation. But up to that point, as springs, they are the same. However- their wear characteristics will be very very different. And getting the hardened bar past its point of plastic deformation takes a lot more effort.
