Watch Press, 18mm to 50mm Watch Back Case Screw Type Precise Crystal Bezel Watchmaker Watch Repair Tool Set - Watch Back Case Cover Press Tool with 20 Dies Pressing Repair

Product Information

I'll stay away from the crystal press in this case. I don't want to take any chances, and after all, I'll be getting myself a crystal lift, and while waiting for it to arrive I'll service the movement and clean the other parts. Five Horotec Jumbo Size Reversible Thread-On Delrin Dies for fitting watch bezels. Die diameters: 40 x 45 mm, 46 x 50 mm, 52 x 55 mm, 57 x 60 mm, and 62 x 65 mm. All Horotec thread-on dies will work with the Bergeon 5500 Press. Is water resistance of this watch of any priority to you? Do you wish to retain operation of the bezel?

The Set includes: 2 Reversible Delrin Dies for fitting watch bezels (40 x 45 mm and 46 x 50 mm); inner side wall depth is 4mm. Hold case over crystal, press foot pedal to compress the crystal, slip case over the crystal, release foot pedal - you are done: This set contains 4 jumbo size reversible delrin thread-on dies for fitting flat mineral crystals. Die diameters: 47 x 50 mm, 52 x 55 mm, 57 x 60 mm, and 62 x 65 mm. All Horotec thread-on dies will work with the Bergeon 5500 Press.This method will work in a lot of cases, but is not ideal in many installations and will not work on crystals with little or no side wall. The compression fit crystal is the weakest of all the crystal types as far as water resistance is concerned. To install the crystal, the skirt must be mechanically compressed to reduce the diameter by approximately .20 to .30 mm before being inserted. If you do a lot of flat thin crystals, these flat Delfin dies give you a more even pressure as you insert the crystal in the case. The second picture shows a die with cut out which is a must for installing crystals with a date bubble. h3 = 5mm (will only need this outer dimension also to be h3 if I decide to keep the 'shoulders' at the top of the model, thinking I may just skip the outer shoulders and have the top and bottom linked by an ark without the shoulders... I will need to think about this....any ideas??? My initial thinking is that the shoulders may flex a little as you push the movement in and grip the movement better, but not sure how realistic this idea is?) - see version 1 and version 2 below. This is my preferred method for all compression fit crystals. Unfortunately, it is not possible for front loaders and you will still need to use the Crystal Lift style tool.

Once I get to grips with it, I'll post the freeCAD design on thingiverse and you can also PM me for it from here 🙂The second most common problems is trying to use a watch crystal lift tool on a crystal with only a slight dome. There are 3 main ways to fit a watch crystal. Each will require its own specialized dies used to properly install the crystal into the case.

One note about the crystal lifts: There are different schools of thought on whether to buy a good brand-name used lift/vise, or an inexpensive non-branded lift. I went with a Vigor that was sold as new-in-box. It ended up working well, but not until after I had to take apart the vise and replace a part. The Vigor has a rubber ring/band that applies spring-pressure to the jaws. They get old and set, and will not serve their purpose. I used an O-ring in it's place and it worked fine.Here is what I sketched in my lunch hour (including a doodle I did whilst on a very boring conference call) on Friday: This type of installation requires a press that pushes down on the new crystal from the top, in a uniform way over the entire surface of the crystal. The pusher/die on the press and the watch case need to be parallel, otherwise the glass will become crooked, and you risk breaking the crystal. Comes in a set of 9 bakelite lower stake dies.

Also l1 is the cutout for the stem/crown, was thinking of making it U shaped rather than square, but would model it as a square and simply fillet the corners to make it a U shape. Once again, Bergeon has listened to the needs of the watch repair industry servicing luxury watches. Bergeon already has the largest selection of screw-on dies, what was needed from Bergeon a truly precision straight screw press to go with the dies Bergeon makes. Well, it's here now Swiss Made with Anodized aluminum frame with non-slip base that can be bolted down if desired. Truly Linear Spindle with Anti-rotation, allow for a straight traveling path while controlling precisely the distance the dies moves downward. Compatible with the complete range of Bergeon and Bergeon type screw-on dies. Supplied with die holder height 21 mm, optional die holders in heights 5 mm and 28 mm are available. Set comes with 6 rectangular dies sizes, exterior length x interior length x width: 23.8 x 13 x 13, 28.8 x 18 x 16, 33.8 x 23 x 19, 38.8 x 28 x 22, 43.8 x 33 x 25 and 48.8 x 38 x 28 mm.

The crystal in question is an armoured or tension ring style, and these are typically pressed in using a press with an appropriate die, and not installed using a crystal lift.
