Can anyone advise how to remove the crystal from a Vertex DD case ?  I think I need to unscrew an internal retainer ?  It definitely isn't just pushing out.

Certainly looks like a ring that needs unscrewing in that photo. It definitely looks like a thread above the castellated ring as well. Separate to the caseback ring thread. It even looks to be a smaller diameter. I would expect that. Once undone out of its thread, it should fall out of the case.

Would it be possible to make a tool shaped like a letter H with one side of the H engaging the castellations in the ring and the other side of the H for you to be able to unscrew it using your hand? Making a tool with 6 'legs' to pick up all of the castellations would be a labour of love.

Is there a lip above that ring coming towards the back of the case ?

It does look like a lip, well spotted. 

Cant tell if its a lip or a section of thread. If it is lip, then i can only think that the slotted ring is spacer for the armoured crystal to push up to. There isn't much info out there about www crystals.

Generally they are popped off with air compression of a sealed case.

If you look in the notch to the right & blow that up, it does appear to just be the top ridges of the thread for that ring (smaller than the case back thread), as Michael1962 said.

Thanks for all the replies.  I'll investigate further.  I never noticed the lip and @Michael1962, I think I will have to form a tool to undo the ring and see what happens.

I'll see if I can get some more pics.

Does the lip stop the notched ring coming out caseback side ?

I sort of am expecting that ring to push against the rim of the crystal and possibly a seal against the front of the case. Hence everything comes out the back.

Nothing else seems to make sense to me. I am trying to imagine why the crystal would not push out unless the ring needs to be backed off to allow the crystal to be pushed out, but then how does the ring come out?

I am new to stripping watches though and am happy to stand corrected. 🙂

Ok.  Update.  Checked under a microscope, there is no lip, it just looks like one.  So, I'm convinced I need to back the ring out.  I'll need to make a tool of some sort.

🤔 so how is this relevant to the crystal coming out. I've never heard of a crystal that comes out through the back. ?

I have no idea ?  I'm new to this.  But, there is definitely a locking ring at the rear of the crystal and no detachable bezel on the front of case ?  So, I am guessing you need to back off that ring ?

There must be someone on the forum that has restored one of these ?

If the front of the case has no bezel and has an internal diameter less than the outside diameter of the lock ring, there is only one way that the crystal comes out and that is from the back.
You could always smash it and take it out the front. I’m here to help. 😉
Take a photo of the crystal side of the case.

🤔 the crystal doesn't have to fit onto a detachable bezel, it can be pressed into the front of the case. Very curious as to why there is a threaded ring inside though. I do have a record www that i could pull the movement out of but I'm away in just over an hour.

A couple of pictures of the front…

Sorry, I’m months away from this one, but…there is an edge to the bezel but I see no obvious signs of previous bezel removal and it is quite thick so it would be difficult to grab an edge on the crystal with a crystal lift. It does look like in/out thru the back…good luck…

Yes, I think yours is recased.  The bezel, the case and the crystal look wrong.  Plus it has a bracelet on fixed lugs ?

How did you get on @B1N9S?

Sorry, I've not been on here much.  I tried to unscrew the internal locking ring, but in the end decided to simply keep the original crystal in situ and polish it.  Looks way better and has a nice bit of patina to it.  I have finished the watch now.  Just needs regulating, as it's running a bit fast.

So the Buren DD also has one of these retainer rings. Mine was stuck and thought I’d find something in my case back tools but most of the nibs are round and taper to the end so are too fat to reach down inside the case. 🙁

Welp, it had been over a week without buying another tool…In the states Amazon sells this Lyecun case back opener:

The nibs are the perfect fit for the notches on the retaining ring…

IMG_1953.thumb.jpeg.1d6ec44102d435ea75ee7be2acdbe56d.jpeg

I unscrewed and reversed the direction of the nibs so the flat end was against the inside of the case. Worked a charm. Perhaps there’s something in your stash of case openers that looks similar?

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      Broken watch stem in watch crown

      By Poljot · Posted

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
