A Heuer diver! Pre TAG, and a vintage watch in a modern shape and size. Quartz movement and a solid waterproofed case makes this a very useful watch for everyday employment. We actually have two of these Heuer Professional divers, “Monnin” 42mm cases, the other with French “Etanche” engraved on the back. Take your pick of these, both with the reference nummer 980.006. They are equally nice, tested and ready for many years of use.
