How to Replace a Watch Jewel and Horia (clone) Tool Review 

This is a very well done video. Very informative with great camera work and explanation of what's being done. Enjoyed watching it!

Great video. This is exactly the situation I'm in. I have this exact tool, and needed a tutorial on how to replace a train bridge jewel and was unsure about the operation. This walk through was everything I needed to see to give me the confidence to do the procedure.

Man am I happy that I found this channel! Your videos are so amazingly helpful for someone else getting started on their watchmaking journey. I have been dreading how much I'd have to spend to get a Horia tool, but now that I know the Chinese version is perfectly fine, I am stoked to get one. Same goes for a vintage L&R machine. I have been seeing units in good condition going for a thousand bucks or more, which is just insanity. Now though, armed with the knowledge and wiring diagram from your video, I am looking forward to buying a more beat up one, and restoring it myself! Can't wait for more uploads, you rock! 😄

Thanks, Mark for a FINE mini-technical... so very well done. I am new to jewel replacement and have a Rolex 2135 needing upper and lower jewels for the oscillating weight axel in the automatic works. With your help and all your other information, I've ordered this tool and the funny thing is, I've already got the new jewels, wisely waiting for finding your video technical to proceed a bit more wisely. Great work, sir! THANK you!

Well done. Thank you. Two comments. I notice that when you need to advance the pusher a large distance you are making repeated turns of the large thimble. The smaller diameter spindle on top of the larger thimble is there to make it quick and easy to advance the spindle a large distance. Then you use the large spindle to make the tiny adjustments you need when actually pushing a jewel. Also, you are pushing the jewels to exactly the measurement you want them to be at. If you re-measure after you make that move you may find you are about 1/100th mm short of where you expected to be. With most jeweling tools (my Chinese one included, and probably yours too) you generally have to go past your target measurement by 1/100 mm to achieve the exact depth you're looking for. This is to make up for imprecision or "lash" in the screw.

I’ve ordered this clone tool and am waiting for it to arrive. Hopefully I have the same luck as you did here. Thanks for the video!

I have the same tool set and found that some of the anvils did not fit the tool so I placed them in a drill chuck and using a fine emery board to reduce the size until they did fit. Once this operation was done the tool is perfectly square. So for a little outlay and a bit of fetling you have a perfectly functioning jewelling tool. Some adverts say that these are made by OEM for the swiss companies and that these are just non branded. Go figure...

Great video there Mark. I learned a lot. I'll be putting on of these on my shopping list.

Excellent viewing and what a precision, affordable Chinese tool set :-)

🎉Thank you for this video. It was as a result of watching that I decided to purchase the same tool. Learned so much from your video. Thank you.

Great video, was considering getting a clone staking tool now I can see that it will work. Also need it more to shrink hands when the originals are a bit enlarged. Thanks!

Thanks for this Mark - great video and tool, glad I found your channel. I have a similar comment to Windsoruk, in that the measurement taken right before pushing out is with the old jewel in place. If you screw down on the new jewel, should it not be the measurement at that point ‘plus’ the reading taken right before pushing out? So for arguments sake using your main plate example, if you screw down on the new jewel and your reading on the micrometer is 21 and your reading when sinching up on the new jewel at 16:09 at about 82 should be 82 + 21 not ‘to’ 21? I’m a bit confused 😕

thank you for so great review, I been looking to this clone, and trying to find thereal deal on ebay but if they shows up goes crazy now I'm going to pull the trigger on this one. thank you again, waiting for another great review like the main spring winders clone.

Just a tip, may or may not be useful to you, but whenever you order a jewel, order 2 of it. It might just slip away in your tweezers, which is rare if you're good, but it's always good to have a backup.

If end shake needs adjustment, should the pivot be adjusted, or the jewel?

Thanks for the feed back, another tool I need.

Thank you for this. I’ll be thinking about one of these in due course.

Thank you for an excellent video. I just bought the Jeweling tool and look forward to its arrival from China. I am not at all confident that I know what size jewel to order. Is there possibly a more in-depth explanation available? I have a plate jewel in a gold setting that needs replacement and I have another watch with a plate jewel similar to that in your video. I appreciate your help. Happy Holidays

Very informative, but I see the Horia clones come in both 3mm and 4mm sizes. Which size did you chose and why? Could you explain what the difference is between the two versions? Thanks,

A link for purchasing it please

hi! is there any missalignment on the anvils and pushers? mine is a little out of center

Great video. Thanks from Spain

Hello, I was watching your video, and it’s great information, and your work is great! Keep the good work! I am very interested in buying one of these Horia clone jeweling tools. Would you recommended after all the time you have had it? I appreciate your help!

Reach out to watch makers Thank you for making this video. I would like to get into watch modifications and eventually gradually start movement restorations. Do you have any directions as to what are some things I can be doing? So far I have bought basic tools more geared for modding from DIY watch club using a NH35 movement. (I successfully changed the date wheel, hands,and dial to aftermarket seiko parts not given by the company) I’ve read practicing on a pocket watch works well being that the parts are bigger and easier to work with. I also want to try and disassemble and reassemble the movement. Any advise on good books, schools or things that has best served you in the past to help build your skills. Thank you in advance! 😁

Hi, can I ask where your sourced the replacement jewel from? From what I have been told, the modern jewels (eg Seitz or Borel) are incompatible with the settings in these antique pocket watches?

Any thoughts about the Bergeon hand press clone?

Does it matter which way up the jewel goes

Where's the link to the tool?

hi, just the video ive been looking for, very well explained. very helpfull .but could i ask, does the measurment 0.02mm apply to wrist watch movements as well as pocketwatches? many thanks in advance.

Super nice

Such a great video, so helpful! Thank you!!!

Thank you very much for the review. Subscribed

Hi Mark, great video, thanks for posting. I just bought one of these jewelling tools, and I have a question with regards to the operation of the tool. When I turn the adjustment knob, it feels loose for the first quarter turn or so, and then resistance increases. This seems odd to me, and there are no instructions with the unit, and I was wondering if yours behaved in the same manner? Thank you, Garry

Big fan

love it mate. thank you !

what are your watch making education credentials?

Does all inserts fits in the upper hole?

I want to order this one thanks

thanks for sharing. 😊👍

Sorry to say but few things are totally wrong in your video. At min. 14.06 the hole from jewel should be 0.02 bigger than pivot (thats correct) but it seems that the hole is big enoug to let the whole shaft thru.. It schould stop at the shoulder... At 9.10 you measure the setting depth from the top... If you repalcement replacement jewel have not the same thickess you have hudge problems.. Measure from the inside, always correct,( as far that the endschake was ok)

I noticed u only went to forty three

That looked like 43

Interesting video - useful link to the tool, many thanks. For the bridge though, are you not making the assumption when taking a reading for the depth that the replacement jewel will be exactly the same thickness as the old one? Maybe that's universally the case (I don't know!) but otherwise you'd need to set the endshake from the other side... I may have misunderstood of course, as I currently exclusively do clocks rather than watches....

Very informative video. I think you found a good niche in watchmaking youtube: finding out if clones of expensive swiss tools are worth the time and money for laymen like myself. Keep up the great work.

Great video. There’s no better between Seitz or Horia, it’s just a personal preference. Quality is up there on both. Some prefer Seitz, including myself, because you can measure the depth of the jewel before removing it, and then you don’t even need to look, just press the lever and it should be right on spot. Sure you have micrometer and can use the numbers for reference but the fact that you can just push it it’s in my opinion a plus over the turning the micrometer to set the stone as sometimes you can use a little hump to push it into place, something that the Horia can’t. Either one is a great choice but it’s all about how one feels while using it properly.

I just got one of these since my budget is very tight. Top knob has a slight wobble but the shaft is very smooth. There’s a couple spots the knob seems to hang up a bit but it could just need a good cleaning from the machining or to break in. But everything lines up well and for $120 I’m not complaining. Finally can learn to replace a few jewels! Thanks for the video.

Hi. Great video. Well done doing this. Where did you buy the tool? Also I thing main spring winders need a Chinese video like this. Must be many more you could do!

love your content very much, i was just curious to get the 21 jewels I thought the excapment wheel and the pallet have hole jewels and cap jewels. maybe that waltham has a jeweled barrel i didnt see

Well done lovely refit job done my Rolex 5513 for up grade olive seitz

Is this a Hamilton 992 movement? I’ve bee. Working on one and this looks exactly like it

I am Bolivar Great job with the tool that is not even authentic.

Thank You very much for uploading this video. It was well made and very informative. I ordered this very tool with the addition of several brass bases. Serendipitous that you made this video just as my tool is set to arrive. Thanks again !

This is fantastic. I have the exact same problem with an Elgin 18s pallet jewel and can't believe how straightforward this is with the right tool. Annoyingly, the Elgin's jewels on the ¾ plate are screwed down and easily removed but the mainplate jewels are pressed in.

This was very informative. So glad I don’t have to buy the high dollar one to get good results. Have you yet found a decent main spring rewinder at a decent price? Thanks Marc.

Excellent tutorial Thank you

Great info! Thank you!

Thank you for sharing this. 👍

Thank you for video I have replaced my jewel on a watch

This channel is so underrated. edit: it wasn't very clear, indeed.
