Here's a mega-rare vintage diver from Sandoz, the Redfish.
The star of the show: that cool red-inflected diver bezel against the black dial with those huge yellow markers.
This is a hefty 42 mm across, excluding the unsigned screw-down crown, by 45mm from lug to lug.
The Sandoz incabloc automatic movement keeps excellent time. This is a nonquickset date model.
Strap it on. Make waves.
