Case and Crystal
The stainless steel case retains its classic mid-century proportions with elegant, sweeping lugs and a smooth polished bezel. The case exhibits well-defined profiles with a pleasing transition between its surfaces. Honest signs of vintage wear, including light surface scratches, minor handling marks, and slight softening of the lug edges, are present across the case flanks and bezel, entirely consistent with regular use over the decades.
