Hi I'm attempting to fix one of my watches I thought the stem was broke but at closer inspection to me it looks like a problem with the crown it's a screw down crown and I'm wondering if it can be fixed or does it need replacing.

Is the crown made by BFG? Looks like the sort of crown you see on Monnin cases. 
 

If the threaded pipe has come out of the fixed tube then you may be able to reassemble it and close the end of the fixed tube slightly.

This is the watch it's from its a guess collection. I thought the same as you by pushing it in and pinching the end slightly but wasn't sure if it was the right thing to do.

It can be quite tricky as you need to allow enough clearance for the square to still engage. If you have a lathe then split collets are very handy for tightening.

I don't have a lathe.

If you do use a pin vice then try to orient the jaws such that they align with the square key inside the crown.

Does any one know where I could buy that type of all in one stem and crown I have had a quick search but only found for omega. I just need a generic brand, or can I use a standard screw down crown with a screw in stem. Sorry if I'm making this harder than it probably is.

Cousins sell them, but you’d really need to identify what type you have. It may be Japanese, or “Japanese style”.

      How do you thread a screw on the lathe without shearing it off?

      By Dell · Posted

      I have only made screws down to M1 & 14BA & I had trouble getting the slot in the centre of the head so I made a jig to help me be more accurate when cutting the slot, here is my video.

      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.

      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 🙂
