Francesco,I like your discussion very much! I want to tell you that my watch 1158s was arrived thanks to an alert of our friend Mark Moss.Now who own it I realize that I have a special piece,it makes a collection alone.I don't know if this watch is necessary to enter in the Olympus.. ... but I must say that if you see one,take it!

At wrist is a joy,you can feel the power of a rare bird and precious material.

Exclusivity is a feeling too,not only production numbers.

Thank you for your interest for this golden treasure.

And good luck!
