Hello all,

A friend of mine has recently acquired a 67 Constellation and is inquiring what the SF on the inside of the caseback refers to. Thank you for your help! Pictures below

 

According to google, SF refers to the casemaker Schmitz Freres.

 

It is a marking of the case maker: cases were manufactured by Schmitz Freres in Grenchen, Switzerland (denoted by the SF stamped on the inside of the caseback).

 

A good looking Constellation but your friend has to get themselves a 19mm strap to fit between those lugs.

 

Thank you! I will relay

 

I said the same thing!

 

Hah, I asked him if he had researched before I post on his behalf .. apparently he hadn’t looked hard enough! Thanks Dan

 

Great spot, very offensive to the eye!
