Crystal press advise needed

Recommended Posts

Consider a screw or a rack operated press, they give a lot more feel than the lever type when gi tying crystals.  The lever type are great for snap on backs.  By the way, I use both.

I already have a screw press made by robur, the problem is most modern specialist dies supplied by swatch and suchlike are made to fit the bergeon 5500 press, there are also lots of generic dies available like the Rolex bezel dies which will be handy to have at home and even the genuine swatch and breitling stuff is made to go onto the bergeon 5500 press.

I already have all the Rolex, breitling and swatch brand specific stuff supplied for me from the brands at work but I am wanting to build up a few tools for at home, would be nice to have the option of buying the generic dies and have a press they will fit at home, I could never afford the Rolex kit I have at work for myself at home.

If the dies are in good condition and  you have a good assortment, I would say this will do the job for you. I was just looking on ebay and descent sturdy ones are quite expensive.   I had many types of glass fitting tools but for tension ring I had two one screw down the other press down and both were very good, if I had to pick one it would be the press down I found the dies were better.

Here is a picture of some of the omega glass fitting and removal tools I had, I would only use for omega watches.

I have just managed to get a 31 set of Dies for £46.... bargain.

problem is the Flat Die is missing and I can't find out where, or how, to obtain another one. Any ideas?

Also can someone enlighten me as to, how to use the Bakelite dies? especially the domed type.

" inner tension ring".   I have bought a few  wristwatches where the tension ring has been cut.  my guess is this is done so as to use "after market crystals" (older domed plastic).  I use a multi - claw tool to install these types,  any comment?   vinn

I came across many like that in the past, many had the wrong glass and ring or both.

Its for putting in and removing low dome watch glasses but the sets of dies are missing. When I was in the business I had two of these and very good they were too. 

Here is a link for you top left picture and bottom left.

First of all that's the dies. Mine were a type of rubber so they didn't mark the glass, yours look as if they have a nice finish around the edges.  Not sure about there age as mine were handed down to me from my master. If I had to guess I'd say 1940's. Yours are made by national I know they also made watch cleaning machines and cleaning fluid and rinse.

I am also really interested in info on the quality of the chinese 5500.

I have a chinese copy of a Bergeon pressure tester that is of outstanding quality. My guess is that the chinese 5500 is great as well, but it would be helpful to know for sure before buying.

I don't think it's really needed to spend more that 50 on a glass/case press. I've upgrade from a cheap one to this
http://www.watch-tool.de/html/second_hand.php?id=0111gm
It's strong, heavy and works very well.

There is also another from the same seller which is cheaper and should work good because the pillars are lined up with the pressing point.

I am looking to get a new crystal press and was wondering if anyone had any experience with either of these Horotec presses.  I have an old BB style press that has served me well, but I feel like I need to upgrade and get one with more die options.  I like both of these because they have an adjustment screw for final tightening.  I believe that the rack style press is their newer design but couldn't find it on their site.  Any insight would be much appreciated.  Thanks!

That is certainly an option.  The BB crystal press dies are all friction fit and I am not sure if the other dies (Bergeon, Horotec, etc) fit that diameter.  I also am looking to upgrade because the press isn't dead on accurate when closing.  I don't know if it is due to its age or if it was abused at some point.  It isn't off by much but enough to be frustrating when you are trying to install a retaining ring that won't go on straight.

For a long while I just used a cheap Chinese crystal tool which worked OK but now I have a array of these tools including the ROBUR and as old hippy says the dies are fragile. However I did purchase some aluminium dies that fit the Robur. The hand held wrench style crystal lift (Mido) tool I have only used once for a low dumb crystal. The crystal lift tool is for high domed tension ring crystals. If you purchase one of these I recommend you purchase a good quality one as the cheap ones need the claws dressing before they work.

Thank you gentlemen.  I appreciate the replies. I have had to make my own dies out of delrin before when so haven't been able to find one that would work for my need.  I guess I am looking for a quality tool that would offer good options and last.  Thanks!

I would recommend the 1st type in the OP pictures, or any other which has been shown here.

That is because with a plates and pillars construction with the pillars not in line with the center of the dies, the plates will tend to open up and the action becomes imprecise, but at least the Horotec in 1st pic has another reinforcement tube.

The forth photo from clockboy is similar to one I had for removing and replacing high dome glasses, a must have tool.

Watchtime I didn't have Chinese tools, they weren't around in my time thank goodness.   :)

Hello at all!

 

I have a general question: I use clockboy’s 3rd photo machine for flat glasses and case backs, the 4th for domed crystals, (I have seen a tool similar to the 2nd photo somewhere in my cellar, never made use of it anyway) but as it comes to domed glasses I am a bit helpless. I only have flat dies with the machine from the 3rd photo. But I have A LOT of domed glasses. Once or twice it worked when fitting a deepfrozen glass into a well heated case by hand - but that’s not really prefessional :) 

So what (affordable) machine (new or used) could you recommend here? Are there special domed dies I have to look for? For a fact, I have no clue, how domed glasses are pressed into place with a machine, I only didi it with plastics (or flat glass) so far.

 

Thanks for any suggestions!

 

PS How much of the case’s size is added to the glass? E.g. with a 28 mm case: should I use a 28,1 mm glass (in crystal I would use a 28,2 mm) or another size?

    • Yes, I think I'm gonna do that.  Thanks!
    • Looks like a fun project. I suspect there is little that would stop it passing modern electrical safety standards, so long as it is earthed, has the correct rated fuse, and a suitable mains cable attached. How does the speed controller work? Some of these old speed controllers use an interesting arrangement of compressible carbon disks as a variable resistor. I have an old Singer sewing machine that uses this arrangement, and a slightly newer Kenwood Chef mixer that uses a triac speed controller. Both are 1970s vintage, and both work well. I would inspect any capacitors associated with the motor assuming there are any, and perhaps replace those with modern suitably rated ones, but the rest I would suspect is fine. If the motor runs, then it will probably keep running. If this is a brushed motor, you might like to take the opportunity to clean the commutator with a bristle brush (not a steel wire one) and inspect the motor carbon brushes too. If the brushes are badly worn or damaged, they can kill the commutator pretty quickly.
    • When working with small metal parts, (not necessarily watch parts, but this applies with those too), I will superglue the part to something I can easily hold, for example plastic card stock, or some other metal, then file away, drill, etc.  then dissolve the superglue in acetone to remove the part.
    • A bit of a classic Timex. So much so that Timex recently released a Snoopy version of the new Miyota automatic based Marlins, and a bunch of other self homages in the Peanuts Charlie Brown, Snoopy & Friends range. This more petite version, I'm guessing from the mid seventies, is the one I remember from my childhood, blue dial and all. It is heading in my direction as a "non runner" (no surprises there), and I was the only bid at £1.93  
    • I have recently purchased a National, Electric Watch Cleaning Machine. Attached is a photo for reference and identification of the model type. As can be seen, it has a fairly typical design, reminiscent of many other types, particularly Elma Super Elite. In fact, I do wonder which came first - the National or the Elma. My musings on this point later. This is a very old machine, circa late 1940’s, 1950’s, but they seem to turn up sometimes on eBay, in various conditions ranging from the “beyond hope” and only really suitable as a donor for parts, and the “old but serviceable” and might-be-worth-a-punt-on machines. This one fell into the middle somewhere, as it was a bit tatty and the heating element did not work. On the plus side, it had all its original cleaning fluid jars and lids, and the motor and speed control gave smooth, controllable spinning and no play in the bearings. I went to visit the seller to inspect it and we did a deal on the spot. This is not always possible on eBay, but as the seller had listed it as for collection only (due to its weight), it was a possibility on this occasion. Once I had it home and gave it the once over, I decided that I would have to either do without heating for the drying stage, or find a replacement element. At the same time, it was very obvious that all of the original cabling was not safe to leave in place and it would all have to be removed and replaced. Any other electrical parts deemed unsafe would also be replaced as I inspected them. So - the idea of a restoration (of sorts) was born. Now - it is not my intention to restore it to the point where it could pass current electrical safety standards, but I will be making it as safe as possible, without losing any of the essential character of the original machine. This is not going to be for resale, so being safe to use is an acceptable compromise, in my opinion. I will however, perform testing on it once the electrical work is done, to make sure that the essential aspects of earth leakage, earth bonds and polarity etc. are passed. (PAT Testing included.) Whilst this is not likely to turn into another example of a superb restoration of an Elma Super Elite (as seen elsewhere on these forums), I hope at least to have at the end of it, a perfectly serviceable watch cleaning machine, and a restoration story - of sorts - of a vintage piece of English watch making and servicing machinery. So first off - the before pictures. This one is a good view of the machine and its cosmetic condition, as purchased. The base is a heavy, cast alloy jobbie, with its original crackle paint job beginning to flake away in places, where the years of cleaning chemicals have attacked it,  but generally sound. The jars still had residues of cleaning and rinse chemicals present. The first wash jar (front left), was particularly grotty and can’t have been cleaned for years. Fairly ironic not to clean the thing, that cleans the things! Maybe it was just left unused and unloved for many years. The mains cable was a cloth-bound type I have not seen in years and could well have been original as it still had the old UK wiring standard colours of red/black/green. Also adding to the vintage-ness, was a very old, Bakelite three pin plug. This must have been one of the first of its type as I have not seen one in brown Bakelite before! (And I am 62...) Anyway, that’s enough for now, as I’m not even sure anyone wants to read much about such an old machine. If anyone is interested though, please add comments and I’ll add to the story as I make progress. At the very least, I hope I have found a potential solution to finding/ making your own heating elements for these old machines, which could also include providing replacements for Elma Super Elite, RM80/90 HCS511 etc. Machines. More details later...
