Home made opener for oversized WW case back

What does a guy do when he does not have an opener big enough to fit a modern watch with 1-17/32 across the pins on the case back?

Make his own of course.

This worked better than I could have wished for. The coolest part is that the board sits flush on the bench so I could focus on pressing down while I rotated, keeping the watch seated in the pins, minimizing the risk of scratching the back.

Far easier than trying to manage a case opening wrench in one hand and the case in the other.

I simply borrowed the replacement bits from another "adjustable" opener, measured the spread in two directions for a 4 point purchase on the case back... drilled the holes and plugged them in.

Now that's using your noodle! I have a couple invictas that are in the same boat..

Paul I use one of those

Peter,

I gave up on two pin case openers two years ago when I ruined a case with one.

They are just too awkward for me to manage and far too risky.

I do use my two way adjustable three pin spanner and have a nice selection of purpose built multi-pin case wrenches that fit most watches... but none were large enough to fit this case.
