How to size folded link bracelet without holes/arrows?


Recommended Posts

Hello, all!

I have a very old LCD watch (Optel Segtronic) from the mid-70s with a folded link bracelet. Unlike other folded link bracelets I've dealt with, I don't see any mechanism for sliding out the center pins. No openings or arrows. Is there any non-destructive way to size such a bracelet?  It would be very disappointing if the narrow range of adjustment on the clasp was all it had!  Since I'm trying to make it smaller, I am thinking of drilling my own holes in the back of the bracelet to force out the center pin (but not sure where to place the holes).

Any suggestions appreciated!IMG_20220909_113046.thumb.jpg.1e09d759feb4c87bfd944ab086059a02.jpgIMG_20220909_113103.thumb.jpg.7cd5102dd4420dab2926b9bb0b686191.jpgIMG_20220909_113124.thumb.jpg.39511037d25d39fb29163639c38aa9d0.jpgIMG_20220909_113146.thumb.jpg.2668354e386c933bccb2c08ac3f247d1.jpg

A new one for me. However at a guess it still can be adjusted by pushing one of the link joiners. Unfortunately not all bracelet links are adjustable and as a extra issue no arrows to show which way to push. It’s a case of fiddling without too much force being applied.

Well, I had no other choice than to go destructive.  The links are too tight to put any tool inside to push out the joining pieces.  My focus was to do as little damage as possible.  The band naturally will only bend backwards a limited amount.

Either with my hands, or with one end of the bracelet held in a vise with nylon jaws, I bent the bracelet backwards, which opens up the links on the inside.  To the right you can see a link that is fully opened (after prying open; bending backward doesn't open the links this much).

With that little gap opened up, I could put a screwdriver in there and carefully open up the links further so that they could be disconnected.

This opening of the links creates some reverse bending on the outside, so you don't want to open them up any more than is absolutely necessary.

Here, the links are opened and the bracelet can be disassembled.

After removing the extra links.

I closed the links by first placing the bracelet in the vice (soft nylon jaws!) and using the vice to start closing the links.  Then I did the last bit by pushing down with a blunt tool with the bracelet on a soft (silicone) surface.

This mostly got rid of the reverse bends on the outside.  You can see that the cheap gold plating came off from the distortion of the steel underneath.  It was already starting to come off in spots anyway from nearly 50 years of oxidation.IMG_20220927_102100.jpg

I am pleased with the results!

I'm not sure yet what I think of the watch!  It looks like I might be wearing it as a consequence of court-ordered monitoring!

    • Could you print the image either enlarged or reduce the the same size as the actual part and then glue it to the steel. 
    • Next is to drill the screwhole this then provides an anchor point so the bridge doesnt slip around while scribing the shape. A cork lid, a pin and a piece of gaffer tape ( 😅 ) keeps it all in place. The hole is measured from the broken part using a hand measuring gauge. Mark the hole, punch it and drill it off to size. The awkward bit is working out where the jumper should be and the detent positions.  I remember watching a youtuber a while back do this with dividers, so i dug out my old school compasses and improvised a little. This bridge only has one hole and to find the detent positions you need two points of reference, so i just worked the second point from one of the corners, hopefully its near enough. Then scribe in the jumper using the two detent positions ( wind and time set ) that were marked and a big picture of the complete spring to look at that helps to give you a feel of where the jumper should be.   
    • Right now I'm making do with a similar micrometer (the one below is $45 shipped but you can find better deals) and a $20 stand. You do have to be excruciatingly careful measuring jewels, since there's no table, but if you don't have the $500 to throw around, it's a nice option.
    • As  I kid, I'd watch Godzilla stomping over buildings and cars and I'd think to myself: Tokyo is a really dangerous place to live... . Cool watch!!
    • Next one up an AS 554, looks like a bit more to this one. First job is to check thickness, most springs are somewhere between .3 and .4, this one measures .35, that matches in with the .4 spring steel i ordered. So for marking up a permanent marker comes in handy to colour up the steel to be marked later with a scriber once its dry. Bestfit provide the extra bit of info for the jumper spring that is missing.
