Read somewhere Oyster bands don't stretch. Myth busted.

well this isn't stretch per se ... it's link holes getting enlarged from dirt and debris grinding the insides over time.

OP, fantastic work, definitely something to be proud of!

That bracelet is beat!

Did the bracelet finally break so the customer sent it in?

Yikes. This 116610LN came in with a nasty whamo on the corner. Under magnification you can the stress marks to the 904L steel.

We get a chance to use newly acquired 904L fill wire in our laser welder!

It doesn't take much. 7 quick laser welds fill in the missing material.

Some smoothing and polishing on the polishing lathe. The high polish and brushed finished are applied.


Back to stylin!

Oh man, I remember when that watch was for sale. Hopefully if it is being sold on again this repair will be mentioned! Awesome work!

Weld up rather than polish down. None of the original material was lost.

Has anyone seen this happen before? We purchased this band from a TRF member, it's an easy fix for us. While asking around, no one seemed surprised. One claimed to have seen this many time before. Odd. Personally it's my first time seeing this happen.

It seems these pieces are welded from the factory. You would think this would be milled as a single piece. Nonetheless we fixed this one right up and snapped some photos. Curious how many more of these we will run into in the future.

If I am not mistaken this is a known defect from the M serial numbered watches around 11 years ago now. The first run are the ones that break off like this. I seen a few 2007 GMT bracelets with the same issue.

A few tack welds to hold the pieces in place. If we're off by a bit we can grind the welds and position them again. This time it all lines up fine.

Seeing these pieces broken off at least one time (that we know of), we went all out with strengthening and adding additional support by welding in a good amount of new 904L stainless.

Here's a shot of the first round of welding and grinding.The first pass is the structure. Second round will be mainly focused on the aesthetics.

More welds (a lot more) to smooth out the surface.

Wow, Michael. That's really awesome skills you have.

In my next life, I want to do this.
That's if karma will not make me a worm in a chicken farm...

cheers
