This is a vintage Nivada Grenchen Chronomaster from the 60's. 
 
This watch measures 38.5mm in diameter excluding the crown and pushers. The case shows signs of its age. The bezel rotates as it should.
 
The dial has aged nicely to a nice matt finish. 
 
The hand wound movement watch professionally serviced in Jan22 and will come with this receipt. At the same time it was fitted with a new crystal and chrono hand.
 
The watch comes on a new leather strap and with a handmade travel pouch.
