Repairing a broken pivot - making a centre drill guide - watch repair tutorial

The pivot is 0.24mm, the pivot is bent or broken, the wheel cannot be replaced. The solution: Drill the old pivot out - fit a new one. But first we need a center drill guide or it will all go horribly wrong.

I compared what you just had done to a work of art. This is not fixing, this is true craftsmanship and immense patience. Thank you sir for showing us your art and craftsmanship.

[destry]

Fantastic craftsmanship! That was most interesting to watch....Nice to be able to produce parts "in-house".

[morganjeffreymorgan]

if i may say, you are a metal wizard of the highest degree.. long story but when i was taking classes for applied machining sciences i asked my instructor how to do basically this and the response i got was " make a whole new one" im goin to email this video to him i think lmao courageous work there

[bobwilson]

The trouble with the amazing macro work in the video is that you really don't get a sense of just how small these parts are! Great work Mark, beautiful craftsmanship and excellent videography.

Awesome video! Now to go try this on my drill press for a really beat up ETA 7750 I got for $85 out of the bottom of someone's parts bucket. (All the pinions are broken off) Was sad to see it in such bad shape. But I think I can make it run. Thank you for all the videos you make! First comment on one but I've watched most of them over the last several months or so trying to learn things, and have you to also thank for getting me into this horology hobby after I watched one of your vids about the 2836 or other movement back then. Now I have an old metal tackle box I hosed out full of watch/movement repairing tools (the basic stuff) and spend half my free time learning what oils do what and searching around for even more tools lol.

I'm thinking "wonder how large that lathe is" and then your *thumb* moves into shot and puts everything into scale. Just amazing.

Mark you are the best in many ways for a beginner like myself. I am grateful to you for guiding me through my first watch service . Since then I have continued and become adept to Venus 175 movement. I have recently bought a vector lathe and a staking set. I really would like to repair a broken pivot on a Brietling premier. After studying your video I am encouraged to try. My question is why not use the carbide spade drill to spot the center and drill. And also I would like to know a source for these carbide drills. I probably won't get a reply because you are so busy but it won't change my respect for you. Thanks. Mark

I can't believe I just watched you drill a hole in the center of such a tiny piece of steel. Amazing how delicate and small those pieces are. I wish you'd tell us how much these jobs cost.

Mark,

This may actually solve a problem I have with a Escape wheel pivot. The movement has no markings other than a K so I am having issues finding a replacement. I am taking your watch repair course and I haven't serviced 1 movement as of yet, I did win several from eBay which should be here any day. I want to service all 5 before moving on to course 3. I've learned so much from your first two courses, and am very grateful you put so much time and effort into producing them.

Mark, very well done.... I love the videos. Been a long time since I've been to the forums- hope to rejoin the watch repair enthusiasts again soon

[dipsyfriday]

Beautiful work. I think it's time for you to create your own watch from scratch! Thumbs up!

[cossiedriverrs]

As ever, VERY interesting videos! Ever thought about induction heating? It would work only on steel, but is very localised, and easily achieved by a very small coil of copper wire, two or three turns wound around the pivot (loosely) and AC current applied. Common in the motor industry, (on a much larger scale). You would get the pivot hot, but not the brass wheel, as the induction does not work on brass. Softening the pivot may then allow straightening without breakage.

At first i was puzzled . "How is he going to fix it, what is he doing ?" . I tried to understand . Then my penny started dropping and i went :" oh no, is that possible ? " . How can that be at that scale ? But apparently it is . Well, that is amazing . It is a good thing that such repairs can be done, many old beautiful watches can survive "through time" this way . Good job . Erwin, Belgium .

[luislimon]

Thanks, good tip on making a centering hole. The jig seems to be to keep the graver from floating. I'm going to try using s small graver, might be able to get sufficiently close to avoid making a jig.

[Portrayalpress]

Superb Mark. You are a fantastic craftsman. Enjoy these videos very much.

[MyRetroWatches]

Great but of engineering skill on show there sir. Did I see Silver Steel and Ground flat stock being used there? My company produces that here in Uk.

Really enjoyed watching this. As always you are an inspiration for me.

[LawrenceButcher]

Many thanks for this video, it has given me renewed inspiration to get on with the repivoting of a 4th wheel on an old Rolex Prince 300 movement I have been putting off for a couple of years! Excellent as ever Mark.

[philoconnor]

Your videos are great. Your style of teaching of patience and depth is great. As a 16 year old apprentice in 1976 in Sydney, I did not have this type of instruction. Great work man. Thanks.

[robertmduckworth]

Well done! Would that we all had your skills!
