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.


Nice job.

    • I have bought myself a Hudie watch which was a chinese brand owned by the also now defunct Hongqi watch factory. The watch is about 25 years old. I want to remove the movement so I can polish the case and caseback, as well as regulate the movement because it's running a bit fast. And more than anything I am curious to see which movement resides inside. However there is a problem. The caseback will not budge at all. I put it in my vice and tried to remove it with my bergeon caseback ball and it will not move a millimeter; the ball just gives out and slips after enough force is applied. I tried heating the caseback too to no avail. I had this problem once before and krazy glued a nut to the caseback and removed it that way but I'd prefer not to do that again if anyone knows any other tricks. It's so stuck I thought it might be a snap on caseback but I do not see any opening to slip a tool in and I also believe the majority of these hudie casebacks are screwdown design like the other similar chinese ones. I actually think it might be glued on because I scrapped off something that seemed like epoxy and in that case I have 0 clue if it'd even be possible to open. Thank you.
    • Ladies and gents, I found the most awesome old gold watch chain!  It has spring links!  I am always so careful with my antique pocket watches, and still fear to drop them, even while on a chain. I've re-staffed a number of balance wheels that no doubt suffered a similar fate. But this chain has lessened that fear somewhat.  So my "watch of today" was my beautiful Elgin 339 clipped to this chain.
    • For me, there’s no binary yes/no answer to this. It really is a matter of feel, experience, inspection under magnification, the age of the movement and what a replacement costs vs invested effort to “revive” it that all play a role determining the answer above. For an Omega 56x series reverser wheel you’ll spend more time trying to revive a reverser (which, by the way is also much more serviceable, but also harder and more expensive to find a replacement for) than you would an a Sellita SW200 where replacements are cheap and easy to find.
    • That's what I did after my Pearl machine stopped working. I've run about 5 watches through it so far and get results as expected. One interesting note is that their customer service says the machine comes with a 2 year warranty but that is not indicated on the website and when asked via email they are unable to provide a copy of the warranty, which I believe runs counter to US federal law 🤷‍♂️  Luckily for me the service center they use for repairs is local to me so if I ever do need to have it serviced I won't have to ship it in its HUGE box.
    • @JohnR725I live in a “3rd world” country (South Africa) and even here you can’t make a middle class living charging $120 to service a watch. I make many times that spending that same amount of time in my day job. But quote the average someone $200 to service their inherited vintage Omega (that stopped working 20 years ago) and you’re told you’re effing mad. This is why watchmaking is dead as a profession in modern times; everyone wants that cool mechanical watch, no one considers what it costs to maintain it. A wrist watch is no longer an essential tool, it’s novelty jewellery. So I do it as a hobby, a make a few videos and I fix broken things. If this hobby can make a little money to at least contribute to its vast expenses then that’s a bonus. I have many other hobbies that are just money pits, so there’s at least that. Speaking of making videos: there’s a lot of criticism being levelled at YouTube watchmakers, either because they don’t show enough detail, or that they talk too much, or that they’re hacks, or whatever other negative thing you can imagine. But these YouTube watchmakers have done more to expose watchmaking to the average Joe than what any of the professional watchmaking institutions have ever done. Professional watchmakers scoff at these “hacks” in their comment sections but fail to see how these YouTubers create interest in the average Joe and turn them into enthusiasts. Anyway, enough rambling from me…
