It is the first time I have come into contact with a balance cock that is not screwed together or inca block type of jewel attachment.

Is the balance/jewel/adjustment pressed together or is it threaded together? 

Any tips are very welcome.

Thanks in advanced.

(oh my, how I had hoped to find two small screws on the underside of the cock)

There appears to be three notches on the underside of the balance cock around the jewel.  My guess is that a KIF tool might fit that, and it would screw/twist off.

Yes, the ultrasonic is your best friend in this situation. Whatever you do, DO NOT peg that hole.

Thls is a non-removable jewel setting. The 3 notches are to allow the cleaning fluid to penetrate and wash out any debris.

This is the first time I've seen it being used for a balance jewel. It does not offer any shock resistance to the balance pivots. It's normally used for the escape wheel and pallet fork jewels.

I have some ordinary balance jewel settings like this I'll pull one apart, it was fitted together somehow.

Ok so i found some to play with.....because I'm kind of awesome like that, shall we have a look to see if they come apart ?........easily without the use of the equaliser ? 

 

I think Nev should make me this from a crushed car engine......... to go with my spandex outfit.

Before i start, I'll point out that i agree with hector about solutions flowing through the setting, not so obvious in your photo but my first victim has 3 finer slots in the top , i think i can see yours also has these.

If it's non removable how would you replace the regulator?

So if you really want to you can break the cock and jewel setting down to these 4 pieces, the regulator arms remove quite easily with a sharp knife under the beat arm then the setting can also be prised out from the cock with the same sharp knife. Thats about as far as you'll get and tbh i dont think you need to go any further the US should flush it out, so I'll  try that. But for interest there does look like a fine seam that will split the jewels holder in two and yes the jewels are seperate....a holed and a cap...the cap is a tad wider as usual. Lets give it a blast in the US and see how it comes out...this one is grubby as hell and the jewel hole is block...so a little poking around is required to free up the crap. To summarise....dont bother stripping it down even to the 4 parts unless you're really fussed about it, just blast it in a USM. Let us know about your outcome with it please.

Yes it comes apart Andy..... to 4 pieces 

I'll flush it, and then try split the jewel holder, 99.9 % sure it wont survive, the equaliser is ready and waiting to take over when it goes pear shaped 🤣

Thanks a ton for the disassembly test. Very value information. I will now put it into my USM and lubricate it with an automatic oiler.

Yes, that was my first thought too. Due to the notches.

I only disassembled that one, but the rest of the examples seemed pretty much the same setup. The jewel holder itself will not split without some specialist tools. It cleaned out ok, you might need to swish it out a few times to get it really clean, uou could try  injection with solutions....like a mini jet wash 😅

Here's what I'd use 😅

      Tissot case back removal

      By watchweasol · Posted

      The ones I have opened also do not have a pry point , hence the reason for the tool. The watch is clamped in the tool and a blade is screwed into the seam, the blade being chamfered lifts the back then the screw shaft is turned and the back comes off have a look on Ali express for case back removal tools

      I don't think I need to know more about the Orient watch question, so please don't write anything related to the topic, but if you know where I can buy the watch's jewels = rubies and gems shock protection, I would like to know.

      It's an exhibition back so no access as you suggest.

      Phinney Walker Mickey Mouse Watch HELP

      By Mercurial · Posted

      I have no experience with this watch, but looking at the pictures from the ebay listing linked above, it looks like the outer metal bezel at the back of the watch may not be part of the case proper.  It looks like the watch and strap are sandwiched together, and an inner case may push out of the rear bezel towards the front of the watch.  A case style similar to the Roamer watches where the crystal, movement and caseback pushed out through the back of an outer bezel, only in reverse - this one may push out towards the front.  To test this, you would need to hold the watch, dial down, supporting the dial side of the watch around the edge of the bezel without touching the bezel itself. Then push down carefully on the inner metal ring you can see at the back of the watch. I’m speculating here, proceed at your own risk. Hopefully someone with hands on experience of these watches can chime in! Best Regards, Mark

      Thanks, Mark. That's the kind of reassurance many of us wanted to hear! Yes, life is unfortunately unpredictable, and it would be a shame if the many dedicated WRT: ers became stranded if, god forbid, something happened to you and WRT stopped working.
