Jeweling tools


CLS

Recommended Posts

I just recently started exploring watches; I have  taken apart and reassembled a few Elgin 18s grade 336. One thing I'm noticing is they all seem to have issues with jewels, either visibly cracked or literally in shards already. Can anyone recommend the tools needed for jewel replacement, there doesn't seem to be a ton of information that I can find on this particular subject?

Setting up to replace jewels will take some considerable expense, I'm still just gathering the tools now.

It also depends on how old the watches are to watch exactly you need. For modern watches you want a Seitz jewel press or something similar, make sure you get one with a complete set of presses or reamers, or you may struggle finding those parts separately, a good micrometer, preferably a watchmakers one like a JKA, but they are getting harder to find for a good price and a pivot gauge.

All of these items do turn up on ebay, but you need to be patient to find one for a good price.

If you are working on older watches that the jewels have the brass rolled over the top to hold them in place rather than friction fit like modern watches then you need other tools.

Have a read of this website http://www.geocities.ws/dushang2000/Jewelling.html

This video also explains the Jewelling tool, its a modern Bergeon, but all the brands work the same.

Thanks!

For now I will only be dealing with older ones, so I should just be dealing with burnished/rubbed in (if my understanding is correct)? 

It looks like a lot of those tools are pretty specialized for stuff (I hope) I won't be needing to do much of. For example I don't think I would need the drill bits or "hole maker" right now.

What would you say would be the minimum I should buy in order to replace a hole jewel, the one in question is for the pallet fork

If you haven't already have a look at this post.

http://www.watchrepairtalk.com/topic/5924-another-watch-butchery-pivot-reshaping/

In particular the second video which is in szbalogh's third post in the thread.It shows you what can be done with the minimum of tools.

For rubbed in jewels as a minimum you need the tool for opening up the brass and for closing it again.

If you are having to buy replacement jewels you will also need a micrometer as a minimum and a pivot gauge would be useful, but you could get by without it. If you need to replace jewels your pivots may need polishing or reshaping, or even replacing and you would then obviously need all the tools for doing that work, pivot file / burnisher, jacot too, staking set etc. To be clear I've only been studying watch repair for just over a year via night classes and I still haven't attempted to replace a jewel, or polish pivots on a watch, I've only polished pivots and rebushed on clocks so far.

Thanks a ton for the advice, I appreciate it

Vintage watches may have burnished/rubbed-in jewels, friction set and jewels in settings.  One beautiful and frustrating thing about them is the huge number of variations that exist among old watches.  Two watches of the same caliber, even by the same company may use different parts.  Whew!  Means you gotta start collecting watch material ASAP if you want to do vintage work.

Thanks for the input. I got the tools to open/close settings and some other tools for jeweling. Ive been tied up in CDL classes/ work lately so the watches are on hold for a bit. Im using the time to gather tools and info

I have a Seitz jeweling tool.  Initially it was incomplete but I've been able to pick up a full set of pushers, reamers and stumps.  Also I've gotten a Seitz jewel gauge.  They're fairly expensive.

There are other jeweling tools besides Seitz, as you see from the Burgeon model.  The Seitz tool was keyed to the Seitz system of jewels; which you can occasionally find online or at swap meets and trade fairs.  I've been working on my collection of jewels for awhile now.  Just got a nice Bestfit collection.  And the Seitz tool is not restricted to their jewel system.  Basically you just need to confirm the outer diameter and the hole size and find a reamer which is close; you can then use a broach to get the hole to the right diameter.  There are a number of tools for determining the size of a jewel hole.  I've got a couple now.  They usually cost some bucks as well.

This book covers the replacement of watch jewels set in chatons. It was originally a home study course that was written around 100 years ago. This was a time in watch repair when the watchmaker actually had to make their own parts from scratch, as commercially produced replacement parts were not readily available at that time.

    • @Murks the problem you have mate is most watch cases out there to buy are for Seiko NH3X, ETA 2824 and maybe Myota 8XXX movements, oh also the big ETA 6978/9 movements which the dials start around 28.5mm. You might find one on a Google search but I suspect your main chance will be buying cheap quartz ladies watches and hopefully find one of the right size and condition that is acceptable. 😞   Tom
    • The anchor pin should be perpendicular when the anchor is sat on a flat surface and if you post a close up picture of the backplate I will be able to tell you the correct torsion spring , running fast or slow is usually wrong Torsion spring. Here is a video from my YouTube channel showing how I set the beat  
    • I think if you want to play Billy big b.ollocks then you have to have something up your sleeve, anyone that knows how to fight, plays dirty. Lets face it a lot of folk that voted for Brexit just rolled uk their sleeves to say up yours EU hoping for good changes. We have idiots for leaders and probably none of them clever enough to clean the shitty stick they were given. I didnt vote, what will be will be. You've signed up to another forum !!! Why you defector , you snake in the grass, you infidel consider yourself shunned.... you.......you........you CAD  😅😅😅😅😅😅🤪
    • I voted leave too, my reasoning was the the EU is undemocratic, no elected officials. I don't regret it but I  am sad that both sides acted like petulant toddlers.  Shameful.  I'm not on other forums but if I was and left this site, would you shun me? Of course not, we aren't petulant toddlers.  
    • This is a type of tool that may be suitable to remove the bezel - though note that I'm pretty sure the watch should be face down - not face up, as in some of the photos of these tools on amazon & ebay! If you try one one of those, put the movement screws back in first to avoid accidents. https://www.amazon.co.uk/Removal-Professional-Remover-Watchmaker-Diameter/dp/B09XCH4QVN?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&smid=A296NCMMFVXSDN&th=1
