Making Bracelet End Links


Recommended Posts

I have several vintage watches with twisted, bent or warped end links. I also have some nice vintage bracelets that are missing the end links completely. Some of them are rare enough that finding replacements is out of the question.

Case in point: my gorgeous ‘73 Pencron. Both end links were damaged, but one was terrible. I made a new end link for it tonight using 0.3mm SS and mandrels I made from 3mm, 6mm and 8mm square stock. I’ll replace the other eventually, but it’s not bad.

The mandrels that I made will allow me to make a wide variety of end links and eventually, my own SS bracelets. 😉
 

Pictured is the old beat up link and the new one, installed.

As this isn’t really a “walkthrough”, I’ll just post some pics and descriptions here. You can fill in the blanks 😉

Here is a picture of tonight’s project and it’s original bent and scratched end link:

The end product will basically be a piece of rectangular SS tubing with a butt or lap seam at the back (or could have the ends tucked into a “B” shape, etc...I started mandrels for this, but probably won’t pursue that route as it’s over-complicated).

The key is keeping the face clamped flat, so it won’t warp, while making the bends. That, and making the last bend on the bracelet. You can’t bend it back without warping.

Cut your SS larger than needed: measure the width of your lugs, then add 2-4mm. Cut a strip about 2cm long and the width needed.

Bend the strip around your mandrel (I am currently using 3/16”, AKA 4.65mm, square stock from Lowe’s and it has been perfect for end links).

Clamp the SS (at the midpoint and perpendicular to the length) in between your mandrel and a flat hard metal surface and bend one flap over (don’t clamp too hard or you’ll damage the metal). Press down hard with a flat metal tool (flat head screwdriver?) to get those bends sharp. I actually rolled mine flat with a large spark plug socket. Fast and easy.


Trim the flap end so that it is even with the end of the mandrel.

Flip the piece over, then clamp, bend and cut the other side the same way. 

The end result will be a “C” channel. I found that I got the best 90 degree bends using my bench vise with the knurled jaw flipped around so the flat side is facing the piece.

Note: all cutting is done with a Dremel and 420 cutoff wheels. Snips, etc cannot be used as they will bend and warp the SS.

This next mandrel is the same stock, cut down to 2mm thick (not great looking, but proof of concept).

Move the piece to this mandrel and wrap the flaps around the rear, leaving one flap at 45 degrees (this will be the bracelet side). Again, press down hard with a flat metal tool to get those bends sharp.

Like I said, not pretty, but the end result...

This can also be done with $2 Walmart clamps and a larger piece of stock if you don’t have a vise.

Remove from the mandrel, make one end perfectly square using the Dremel disc face or other flat. Measure off of your square end to cut and square the other side to exactly your lug width.

Cut a slot on the rear of the link on the lug side for removing the spring bars in the future.

At this point, you would trim the bracelet side, but I didn’t need to with this one.

Clean up flashing, file edges lightly, round corners and finish by removing blemishes from the face with 600-1000 grit in even, parallel strokes for a brushed finish. Follow up with metal polish, only if you want a mirror/chrome-like finish.

For two tone, mask your brushed areas and polish the rest. 😉
 

Slide your 45 degree flap trough the bracelet slot and carefully bend the flap shut so that you don’t warp the face (if you want a curved face, gently squeeze the ends of the link with pliers to bow the face out...this is tricky at first).

You only get one shot at it. If you try to open it back up, you will warp it. Do it right the first time. 😉

Sanded piece is pictured on the left, unfinished on the right.

My tools could be more refined. I’m working on that. This was really more of a “proof of concept” trial that turned out very well. 

If someone were so inclined, they could make mandrels with different face and/or rear profiles to make them curved, etc. I started work on several, but the square mandrel has worked so well and easy that I doubt I’ll pursue more complex profiles anytime soon.

If anyone has anything to add or other ideas, please post them and your results. 🙂

I just did this on a whim the other day and am a bit embarrassed about my “tools and supplies”. The square stock was purchased at Lowe’s for around $2 per piece and the SS I found at...ummm...Walmart. 

I just walked around with my calipers in hand looking for SS. Found lots of nice, low cost stuff that I’ll be able to make my own rally bracelets out of. The SS I’m using here came from a $7 small trash can (it was a 0.3mm veneer on the lid, so the can is still useable = free SS).

I’d had the idea for a while, but was finally motivated by my sad looking Pencron end link staring back at me.

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....  
    • Hi there, welcome here.  
    • yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
    • Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
