The Nivada Grenchen F77 is a bold revival of a watch first released in the late 1970s—an era that embraced sharp lines, geometric cases, and the rise of integrated bracelet sports watches. With its distinctive angular case and integrated steel bracelet, the original F77 was a symbol of cutting-edge design at the time. Fast-forward to today, and this rare gem is making a comeback—reissued with meticulous care in two iterations: MK1 and MK2.
