One other part I made on the "new" lathe is a proper strong and deep enough die to deal with tall crystals such as on the 1680 and VERY tall one of the 1655 (Sea-Dweller). Most foul on the crystal.

My old solution was a 30mm 12-point socket. it works, but it does not press the retainer flat and square relative to the case top surface, so I have to go back and "peck" it down with another tool all around the crystal...

Here it is: (The blue Tudor will be it's first victim)

Nice. I have made stumps etc for my staking tools but I use brass which I find less likely to damage/scratch parts. So many more options are possible when you have access to a lathe. Wish I had room for larger lathe but!!!!!!!

This was going to be scrapped. They did scrap a second one, so I collected all the useful parts I could before it left. 

Then I spent a few hours cleaning it up. I had sprayed it down with oil prior but it was all browned up again. 

The compound was a project in itself. I had to figure out how to disassemble without breaking/loosing any parts. Hardingebuses cam bolts to tighten the locks for the compound angle. Those don’t come out easy after 50-odd years of neglect.

I made another one, a better one, for the 16610 case and it works fantastic! The bottom edge is at the exact angle of the retainer, and the inside step keeps it perfectly centered. Again tall enough to not foul on any crystal.

I have it drawn and can have more made if anyone needs one. Also made from 6061, they will be $165 each if anyone is interested. I'll eat the tooling/set-up cost but I need at least five committed before I give the go-ahead to make them. (photos are of my hand-made prototype) 

I will also refine and have a similar situation for the four-digit cases (refine what I made originally). I figure pricing will be similar, but no drawing yet to confirm pricing with the machine shop. Just PM me if you are interested.

I love to see folks make their own tools. That's the great thing about having access to a mill and lathe. If the tool you want doesn't exist, you make it.

I usually draw the thing in SolidWorks first, then print out dimensioned drawings, and then go to the shop and make the thing.

Great job on that!

My solid works was a post it note. But I had the retainer with me to ensure it was fitting right. 
 

Now the drawing is in a 2-d drafting program. It does 3-d but I learned on auto cad lite which was 2-d.

I note with some amusement that I responded to this topic well over a year ago. At the time I was just impressed to see someone having made a nice tool. Now I find myself in need of this exact tool (a die to press the gasket retaining ring on a Rolex 116610) and I spent a few hours at my shop making one earlier today.

It's not nearly as nice as the one member-Tudor made - it's just a ring that can be used underneath the die in a crystal press. But it's a start.

    • I would repeat what @nickelsilver says, and even more. I have at leas 10 old thread plates and I have never seen one that will cut like a normal die. I don't know if they are completely worn or have never been sharp enough, but I find them completely useless. And, for the new Indian ones, I have heard only bad things. For sure, if one tries to cut more thread on a winding stem, this hole of the plate is ruined. Further more, I have bad experience with all watch size thread dies that I could buy from the available machine  tool shops here. They could not cut normal thread even on brass rod. The size was significantly smaller and the pitch is like it should be for the claimed size... The thread shape was bad too. I will explain how I do threads. I use lathe that can cut threads and thus I can prepare perfect taps. I use milling attachment instead cutter in the tool post and so I can cut thread even on hardened rod. But I prefer to harden the rod after thread cutting and temper it only to light color change as to have the maximum hardness. Then I make a tap out of it by grinding. I prepare my dies for screw thread cutting with the taps I have prepared as described. In watchmaking, dies exist and are often used that are not cutting, but rather forming the thread. They are like nuts and don't have cutting holes and edges. This kind of dies I prepare and use. You will need soft steel plate , drill a hole in it, then cut thread, then make chamfer on one side, repeat the thread, harden. You can temper just a little or leave untempered, depending of the steel You use. Using such die is with soft steel rod (or completely annealed). Good oil is to be generously applied. The rod has to be with smaller diam than the thread size (about 0.8 - 0.9 x ), the diam is better determined by tries. The rod elongates by the thread forming too. When I have to make screws from harder material like SS, I just cut them on the lathe. You screw needs hardening and tempering to be finished as real screw.  
    • You could make a guide/jig. Cut a slot in a piece of metal approx the same thickness as the screw head, then drill a hole (screw head diameter) in that slot.
    • Tried a SR920W and its completely dead after 3 weeks 🤷‍♂️ 
    • Thanks so much for quick replies. I got some watch repair tools ordered, and will get back with pictures once I removed the back lid and get into it 🙂
