VERY NICE! Seiko KINETIC with SAPPHIRE CRYSTAL FRONT AND BACK. Model 5M42-0B11. Stainless steel. Silver and gold tone highlights. This is a KINETIC watch. So it winds by simply shaking/spinning the watch. No battery or winding needed. Condition: Fantastic condition as seen in pictures. Cosmetically very close to being new with light signs of surface wear only. No scuffs, cracks, or chips in either the front or rear crystals. The time does set. RUNS AS SEEN IN VIDEO. It did stop a couple times so the capacitor will need changed out (easy 5 minute job as it is just like changing out a battery). You can do this at home or any jeweler can do it. Im not really sure what the top button does but it seems to be stationary. Im sure there are further instructions online. Location E1, MER, FBMP
