Welcome to the forum. Have a similar conundrum with an Omega 19''', I presume these took an oval jewel and have been searching for a couple of years now. No luck yet.

Hello Blacklab , thank you for your reply. Yes, it is very hard to find. I tried ebay and some UK web site. No luck yet  :D

You can purchase them from Cousins but I am not sure how to measure to order the correct size. Someone else on the forum might be able to advise. I have replaced a loose roller jewel and used shellac to attach.

Unfortunately, although Cousins do sell them, I don't think they sell anything large enough for this size. The shape is also a problem.

 

I might try and experiment to see if a D shape would work out (well secured with shellac), but because of the size - unless you can find NOS then you may have to look though your scrap movement box for something suitable.

 

Making one may be the only guaranteed way to get what you want, but this is quite a skill and a lot of polishing.

Thank you Mark, making a jewel is too difficult to me.  I am not sure yet ....maybe... I might try 2 pcs of D shape combine into 1 by polish the flat surface.

I finally found the roller jewel and fixed the watch, It is working now, However, my timing machine could not  detect the watch as unknow amplify (I guess). Does anyone know about the amplify? 18000? 19800? .....?

 

I share more photos here. thank you.

Hi Blacklab, please let me know the oval jewel width you need. I have a few here but not sure if it suit for you.

Great work, great watch & even a better offer, thanks. I am looking for a 0.58mm or possibly a 0.56mm (my measurements  may be a bit out).

Wow, that's a beauty!  I've never seen a pallet shaped like that.  What's the function of the part opposite the fork end of the pallet?

Hi Swordfish,thank you, I believe it is for balance function opposite the end. .

I second Swordfish's question: is there a function for that part? or is it just decorative? Maybe a decorative Jewel?

Agree it is also decorative .....its very interesting looking it moving left and right.

You have probably noticed that your pocket watch has a Chinese inscription on the plate, near the case hinge.  As luck would have it, I've been studying Chinese at the local university.  I asked my teacher what the inscription means.  She said that it means "give authority."  In Chinese, there is no conjugation of verbs, so one cannot tell who is being described as giving authority, or even whether the inscription is in the imperative mood.  I'd like to think that it means that the watch can be relied on because it gives an authoritative reporting of the time.  But for all I know, it is nothing more than the name of the manufacturer.  

 

avkxyz, there must be a story behind this watch.  At least here in the United States, one doesn't run across antique Chinese pocket watches every day.  What's the story of this one?

It's nothing more than for decoration. That jewel for the impulse pin is in fact a very common shape in old P/W's. In the verge type the pillars have some wonderful decoration the same with the balance cocks, people just collect balance cocks and make necklaces out of them. the other thing to look out for is the end stone there are some great looking ones attached to the balance cocks.

      Lathe motor advice

      By JseTay · Posted

      I sure appreciate your comment! I will look into one of those or maybe something similar. I of course will check your video to have a better idea.  by the way, that’s a beautiful lathe! Mine is a little peersless, but I just bought a Boley & Leinen that is on its way. That’s the one I am looking a motor for. It comes with a motor, but I want to replace it for  one that has a speed controller.

      Etachron regulation system

      By JohnR725 · Posted

      This conversation is becoming a very confusing. The etachron system is a very nice system for manufacturing watches. As you know it consists of two components the stud and the regulator pins. Beautiful thing of this system is you can open up your regulator pins center the hairspring and as you close the pins they will close equally on both sides providing you centered it in the first place. It's not like you're going to become closer to one side or the other as the definition of the regulator pins is a bit confusing it's not exactly a slot sort of. I'm thinking maybe a little eight reading will be helpful for you. Then the file name was changed by me at the US patent but the wording of Seiko may or may not actually be attached to it soared up? I just did that so I can find it in my files. Normally patents are in people's name if they work for a company the company name will be there you'll notice the person lives in Japan which is interesting as the name would imply that this is a Swiss product. Somewhere I think I have the patents for the stud and I believe that is Swiss like a lot of things their Japanese and Swiss and then the Japanese let the Swiss name stand as it seems you more popular in case as you read up on the patents of the regulator pins or pin will see and it should explain exactly how and why it works also why it's important to always close at an open in specific directions because the pins actually have a shaped to them it's very hard to see the shape as it's very tiny.   As a reminder with this system it's mass-produced. I wouldn't be at all surprised if they use cameras and computers to do all of the adjustments.  The meaning of this is that the majority of watches will function as there supposed to and do what they're supposed to do the system will allow us for some minor in tolerance and has more than likely as I said no human hand is ever touched those watches that's the way they left the factory and they work fine.

      These still seem stupid expensive for a bottle, but still £100 cheaper than than the Moebius ones. Anyone have any experience of these: https://www.cousinsuk.com/product/epilame-fixodrop-special-bottle-horotec
