Remove links from metal watch band
This was on a Seiko Dive watch SKX007. This has the metal links joined with pins, which, you will find, are split/spring down their length.
I used a neoprene mouse mat as a work surface, which was ideal as it
allows the pin to move out, whilst supporting the links and stopping
any slippage. I also rigged a table lamp close by.
There is an arrow which shows in which direction the pin needs to be pushed to remove it. Look carefully and you see that one end of the pin is slotted a little, the other is plain. Push the plain end in the direction of the arrow firmly... it's a leap of faith.
As a tool, I used a cocktail stick to start with. It required firm pressure and then it suddenly gives. I was able to draw the pin out by hand, but used pin nose pliars in one instance, as some pins offer more resistance than others. In most cases the cocktail stick worked (I got through a few). I then graduated to a thumb tack which was more reliable, but metal to metal, so a bit more worrying.
Sliding the pin back was simple, though take care to get the smaller links the right way up when it is re-threaded. I pushed it home the last few millimeters with the flat side of the pliers, giving a final push with the cocktail stick. Good luck. Simplysimon.
