This 33.5mm. Le Coultre power reserve is an early example dating to 1950. The black dial was expertly restored and retains the original gold toned markers, minute dot markers and hands. The gleaming stainless steel screw-back case measures 33.5mm. and retains the original winding crown. I must say-this glossy black dial really looks amazing! You will find yourself gazing at your wrist often.
