Buyer's Comments

This model features a bi-directional rotating black bezel that carries on the tradition of model 155, which was officially adopted as a German Air Force chronograph in the 1960s. It has the minimum necessary specifications, such as a stainless steel case, screw-down crown and case back, and a reinforced acrylic crystal as required by the German military. The black dial and white hands provide excellent visibility. The case has some minor scratches, but no major damage. The crown and pushers operate smoothly. The strap is a non-original leather band.
