As I was saying, this watch has a unique snapping motion strap, which digs it’s teeth into the strap and will fit any wrist snuggly. You can see this from the photo below.
Certina watches are hard to find in this good condition. If you look closely at the face you’ll see the amazing funky font that displays “argonaut”. This is a head turner of a watch, and the colour of the face (deep purple, dark maroon) really compliments an outfit.
This is one of those watches that I really quite fancy keeping, and have to resist the temptation of wearing around the place. It’s a cracker.
