Rolex Oyster Perpetual 41, silver/white dial

The $189 version built-in the Japanese-8215 self-winding movement (power reserve of about 35 hours, error of about 15 seconds per day), and the $539 one is a super-c version built-in the Swis-3235 self-winding movement (power reserve of about 70 hours, error of about 5 seconds per day).The two watches look the same, with the 3235 movement's second hand moving a bit more silky smooth than the 8215 movement. The bracelet and internals of both versions are constructed of 904L stainless steel, sapphire glass, luminous hands, and weighing in at about 4.3 ounces, it definitely no cheap feeling on the wrist.
