Rear deck square head fastners

[Ragnar Arntsen]

Hi all
As I was going to fasten the rear deck bolts,I found it difficult to use a plier.
Beeing a former watchmaker I found the tool needed.
It is the winding key to grandfather clocks. The Swiss watch industry has a number system on the keys. It starts with #1 and is 2,5mm. The key I used is #4 , it has a 3,25mm square and is a little bit too big,but it leaves much of the paint on . I grinded of some at the square end to be abel to axcess the heads when countersunk. Find your local wathmaker and buy the key there.
If a smaller key is needed ask for the pocket watch key,it starts with a square of just 1mm
Hope this is of any help
Ragnar
