This 40mm Panerai has a brushed stainless steel case with a high quality polished stainless steel bezel all of which are held to the wrist with a nice black leather strap. The dial is black with a date and small seconds sub-dial to keep track of the time down to the second. It has a Panerai OP IX calibre automatic movement so it will never require a battery, running off of the movements of the wearer, storing inertial energy, and to cap it off, it has a power reserve indicator to tell you how much inertial power is remaining.
