Google - "murphy seiko bezel" and you will find. I have one. To me it has the quality feeling like it was made by a true machinist. Bi-directional, but very smooth. I have a 1-12 GMT bezel insert to fit in with the fact the bezel turns either way. Very coin edged.Man that a real grip on it. Looks really good.
Are there any for the 6309-7040's ? Especially like those
" Coin Edge Ones ".
Some one has to make them somewhere.
Or have to try doing it myself.
