This Sinn Chronograph reference 956 is still in production and can still be ordered on the Sinn homepage.
My friend sent me a couple wristshots of his Sinn Klassik 956 Chronograph which I wanted to share with you.
I like the dial layout for a chronograph timepiece, combined with a power reserve indicator showing you if the powerreserve is full or halt full or empty.
It is a hefty watch which sits well on your wrist.
