Crystal press advise needed

Recommended Posts

Thanks oldhippy, this is my "Jack the Gripper" in the photo - can I use this shape of "fingers" for real glass as well? When tightened too much, it grips so hard that it punches holes into the side of plastic crystals :)

Can I use this tool for domed real glasses?

 

PS Yes, I have a useless chinese as well, it has lasted for 10 watches, now every crystal slips out of the fingers.

So... There is no way putting my glasses with my tool into place. The mounting device is too high, the glass doesn't stand high enough for gripping. 

But even when picked up from a flat surface, the tool always slips from the glass. The glass has a tilted border (see photos). 

 

Wrong tool / wrong glass /wrong technique?

Think there is a misunderstanding of the tool required here. Firstly "Mark has done some great video's on the removal and fitting of various crystals. Suggest you look them up on YouTube.
It's inappropriate to use an arcrylic crystal lifter on mineral or sapphire crystals.
Why have you only flat dyes ? Even inexpensive case and glass press tools come with a selection of dyes, including concave dyes suitable for domed crystals. The problem today will be obtaining jumbo dyes for the modern larger watch but they do come up for sale on various sites.

Yes, this was just what I was thinking! I only have flat dies because I have not bought a better set yet :) hence my question, which one to buy. Perhaps I misinterpreted the above suggestions for my crystal-tool. 

I will have a deeper look into techniques and dies/tools.

 

Thanks so far!

old hippy is right, but for clarification high dome acrylics = crystal lift, low domes = press, but the method is different from pressing a mineral/sapphire/tension ring, with a low dome acrylic you basically have to use the dies to make the crystal curl in on itself slightly, then slip the case/bezel into position and then release the pressure so that it locks in place to the bezel/case. It's probably been properly demonstrated or explained somewhere around the forum before, but i could just imagine someone trying to puzzle that out from scratch.

I'm a very new beginner hobbyist.  Would this low cost Chinese tool work for removing/installing crystals and pressing on case backs?  Anyone have one?

Thank you

I would say buy the blue one that actually has the shape of a press. This one can work but if you press too much, since it's a cheap one, it'll break and you might just break your watch as well.

Stick to the blue ones that cost 15$ or whatever... They're not as good as the original ones in that you might get one that is slightly misaligned (from what I could read in some comment) but it'll be better than this one.

i do not recommend this type because the force is not between pillars and it will lose plane under medium pressure. If you want a screw type make sure that isn't so.

I purchase a cheap one ...It did work fine the one time I used it ..I'll enclosed a picture at bottom ...Which one would be a recommend unit if not the one I already have.

That is fine because the cast construction is not subject to distortion, and being of the lever type it allows better feeling.

Often what makes the difference is having the correct dies in terms of shape, size and material.

Thanks...there is one thing I don't like..depending on the watch if I screw the dies all the way in the dies do not reach ..I put a nut and washer on to extend reach but haven't tried it yet

As near as I can find of another type I had for tension ring and flat

This very good glass lift and fitting tool for high dome glasses

Beware of cheap Chinese types. You know they won’t last because of the price. Good tools will last you a lifetime.

We have a lot of people here using hand held and bench Chinese presses. No reports of breakage or other problems, generally these are great for beginners. Isn't always necessary to spend a lot on tools. I have an Anchor copy of MKS screw type, works good and has a sturdy build, link is a previous posting in this thread. 

For the ease of finding info I have merged various threads in a pinned topic.

Some generic postings moved to another thread. Please stay on topic: Crystal press advice

Has anyone ever used a case press like this one:

It looks reals sturdy from the pictures, but i would like to get someone's first hand experience.

My experience with the cheap Chinese crystal presses is very poor. I ended up buying a Bergeon No 5500 and I'm remarkably satisfied with it. I recorded a video of the very first time I used it and you can see it via this post.

    • I use 3 and 4 jaw chucks, large and small on a "compound lathe".   how does a " bezel - chuck" grab a crystol?  with a 4 jaw,  you invert the jaws and grab the inside so you can cut the outer diameter.   do they make chucks for jewelers lathes?   vin
    • Today, we have a big chunk of 1973 in the form of a Timex Viscount automatic day/date. This repair fought me every step of the way. It arrived with the winder connected to fresh air, and needed a complete strip down to get everything back in order. The day detent spring was misaligned, the date wheel was misaligned, the winder weight was loose, the thing was filthy both inside and out, and even getting the back off initially was problematic. I probably spent a good half hour simply trying to figure out why the day wheel refused to co-operate before I noticed the spring wasn't actually doing anything when the disk was re-fitted, due to the spring being in the wrong orientation. I suspect it got a good hard knock at some stage, which dislodged a bunch of stuff, possibly due to the frustration of the previous owner, as a result of the day wheel not turning. Everything is now all back in order, the hands are correctly aligned, the day and date kick over correctly at midnight. It is ticking away with that characteristic Timex chonk-chonk-chonk and winding nicely. I'm not sure it is going to stay on the hair puller band, I may swap it to something a little more comfortable, as I don't particularly enjoy the bald arm patches look, and my Nordic neanderthal genes mean that my arms are particularly furry. This is what it looked like when it arrived. I'll keep it on for today, and regulate it tomorrow once everything has settled down from the surgery, but it is keeping pretty good time so far. The crystal polished up well, but I still need to give the case back a quick whizz with the polishing pad to get rid of some apprentice marks, probably due to some previous owner's attempts to open the thing.
    • It's, of course, a counterfeit, and not even that well made. Below how a genuine similar one looks like, from Chrono24. As suggested you should open it not just for curiosity but to check if there is water ingress or battery leaking.
    • Hi Gents,   Currently, I try to recondition a 1970 Regency chronograph with a Landeron 248 movement.  Everything is going fine so far. Ordered new mainspring, glass, gasket and pushers as they were a bit stiff. The case itself has been replated as it was also quite worn. I dismantled the whole movement and this is where I have some problem and I would like to ask more experienced members' opinion as I am only a novice. Straight to the issue, I could not remove the 4th wheel. For me, it seems that the bottom of the 4th wheel pivot was formerly broken but still long enough to sit in the 4th wheel bottom jewel hole. In addition, it looks that a small pipe or so was fitted from the bottom plate to the end of the 4th wheel pinion. And this is the reason that I cannot remove it.  Could it have happened as I detailed above or it is a normal thing? Should I remove it anyway and change the whole 4th wheel or the pinion if I can manage to find a replacement. What can be done? what do you suggest? After this, I decided to carry on like that and at the end when I will measure the accuracy, it should show some really bad results in case if there is any affection. And now got to the second issue. So, at the end of the cleaning, I found a small pin in the bottom of the horosolv jar. I managed to find its place. However, I am not quite sure how to fit it again. To be honest, I cannot see its purpose really. From the bottom end, it is underneath the setting lever, and from the top plate also it sticks out hardly any.  Have you got any idea how to solve these problems?   Sorry for the poor quality of the pictures. Hope they help though. Please detail your answers as I am just a beginner. Any help is much appreciated. Gabe   P.S.: Please ignore the notes on some of the images which are not related to my issues. Thanks.
