Crystal press advise needed

I would still say 100% don't buy this model. But if you were saddled with it anyway, and you already have or can beg an M6 helical insert kit, you can make it less worse. 

Good work. However even if perfectly built I still recommend against buying this type, because the design is wrong. You can't have a light, screwed in press where the screw forms a triangle with the two skinny pillars. As soon some force is needed as when fitting certain thick diver's crystals or bezel, it will distort and press unevenly. When the spindle was placed in between pillars that wouldn't happen, below a link to a type made like that, still cheap but at least would work better for sure https://www.ebay.com/itm/291052426947

Since this particular subject thread already exist, I thought I'd post this here (instead of starting a new thread).

I would like to know if this Bergeon 5500c  8" Crystal Bezel Press Case Back Watch Case Min 1/2"  is a reliable and cost worthy tool to purchase to remove a crystal?

Or would I just be wasting my money and look for something better, quality made?

Is it even a true "Bergeon" tool or a knock-off reproduction?

Anyone here actually owns this specific one?.....and if so would you be kind enough to post your thoughts?...opinions?....reviews?...etc.

Thank you in advance.

Vevor is possibly the largest Chinese retailer for various machinery, they always have the best price, of course nothing they sell is manufactured outside China. Above I have explained why I recommend against presses where the spindle is not inline with the pillars, or at least have a cast body or sturdy construction. If you go with this one let know how it does.

OK....I see and yes that does make sense now as to why the price(s) is so much cheaper.

I think I will pass on it since, as you previously mentioned, the spindle is not always inline with the pillar and well I really don't want to mess with having to return / ship back an item, etc.

I take it that ordering one of these particular models is a hit or miss, since it's really not guaranteed that it's perfectly alined?

Sure you can use an inexpensive crystal press...I have one with the curved metal base and aluminum dies with a few teflon bases for pressing  casebacks They work pretty good but be careful not to put too much pressure or you'll break the crystal and possibly damage watch case.

Hello, 

I resume this post to ask a beginner question hoping that some experienced member can give an advice.

I own a cheap Chinese press too (threaded) with some basic dies for casebacks.

Since my work on watches is only an hobby and I rarely fit a glass (like once every 2 months), as of 2022 can someone point me to a complete and not too expensive dies kit that can permit me to fit every type of acrylic and mineral glass?

I would like to buy a die set that I can, if possible, reuse in the future with a better press if my work on crystals becomes more frequent.

I will buy a crystal lift for the high domed. I usually work with 30 to 42 mm case size watches.

Bonus: what about square, oval or tonneau shaped glasses? 

I know that this topic has already been discussed but too many information and a complex "crystals taxonomy" are really confusing me!😅

Thank you very much.

Regards.

I don't know if it will fit every type of acrylic and mineral, but I'm liking this set (M6 threads):

You will also need domed dies for the acrylic crystals if you don't have them already. I mentioned the ones I got in this post.

My answer can only apply to those with 3D printers.  I have a BB Crystal press and a full set of their aluminum die.  However, I never use them.  I print the die I need on my 3D printer.  Rarely have to print any more because I have printed so many.

Your question about odd shapes--had not thought of that.  But, again, I can solve that with my printer.

Hi LWS   I take it thet the ones that are printed are the snap on  type.  Might be handy for menbers if you could post the patterns some time, not having a printer I buy them.      cheers

Correct, the BB crystal press uses a non-threaded post with a small spring-loaded bearing that catches the fitting on the top.  Just a post on the bottom.

Are you in the US or on the other side of the pond?

I have heard good things about this one. I’ll be clear though, I don’t have one, but there is a YouTube video of an enthusiast using one.

Problem with the lever press is that you are relying on your own strength to press it in. With a Screw press, you have far more control over the pressure.

There are many of these available on Ebay and at retailers. Listing says they will accept generic and Bergeon dies.

As I wrote many times before, I do not recommend this type, the shaft is offset from the pillars, it distorts more easily. This one has strong pillars than the supercheap ones, but the issue still exists.

Lots of professionals will tell you exactly the contrary and they have a good point screw conceals the force, no much force should be needed anyway, consequence is, crystal breakage.

Careful with these as there are many some are good some not so good. 

I had different types. Robur was one I had but the dies break easily. These are the others as near as I can find. The one in the last photo I found to be the best type but I can't remember the makers name.

Good advice, thank you.

    • Plastic crystals have a lot of stress and this will eventually show up as a lot of hairline fractures on the crystal. If you are saying you want to save the original I would recommend not bothering they are considered consumables. Get an original crystal installed by a proffessional is the best route. Not much difference in price to buying one from them and installing  it yourself. Anilv

    • I have a few questions on the use of a (lever-type) jeweling tool in the adjustment of jewel endshakes, as I have never done this before. 1. If the endshake is too much or too little, how do you choose where to adjust the endshake? Do you adjust the endshake on the train bridge, or the main plate, or both? How do you decide which is the best? 2. When inserting the pusher into the spindle of a lever-type jeweling tool, such as a Favourite, is the best practice to take out the entire spindle from the tool frame to insert the pusher? And likewise, take out the entire spindle from the tool frame to remove the pusher? Or is it perfectly ok to insert or remove the pusher when the spindle is still inside the jeweling tool frame. Which way is safer/ best practice. 3. Is there an attachment to the base of the jeweling tool to hold the mainplate or bridges? I don’t seem to see any for sale, new or otherwise. Can I make one?
    • In the USA, you could try: https://www.jewelerssupplies.com/ or http://www.julesborel.com/ Cousins in the UK might be a possibility (although Waltham is a US watch, I'm sure some of them made it across the pond). https://www.cousinsuk.com/ Mark also has a list here: https://www.watchfix.com/category/watch-parts-tools-suppliers/watch-parts-tools-suppliers-us/
    • Yup. It's like the song from The Greatest Showman.... Never Enough! Never, never...
