![]() Military-inspired timepiece featuring green dial, luminous accents, and day/date functions.Today these watches are under the name Seiko Kinetic. The watch is entirely powered by its movement in everyday wear. Seiko produced the first automatic quartz that combined the self-energizing attributes of an automatic watch with ‘quartz accuracy’. In order to maintain accuracy, wear the watch for 8 hours or more per day, or manually wind the main spring by turning the crown. Automatic watches do not operate on batteries, instead, they are powered automatically by the movement of the wearer’s arm. It’s of stainless steel (bezel), has luminescent hands, a 21 jewel movement, analog day-date, case diameter of 37 millimeters, and more. It will hold about 40 hours of stored kinetic energy. Okay they don’t call it that, but you might as well. A rechargeable cell (battery) will store energy to power itself during the night or when covered by a wearer’s clothing (e.g., sleeve). This solar panel converts the light into electrical energy to power the watch. Sunlight (and artificial light) are absorbed by a solar panel. An oscillating weight turns on a pivot (upon movement) and keeps the mainspring wound. However the natural motion of the wearer provides energy to run the watch. ![]() The trick is remembering to keep it wound up!Ī ‘kinetic’ self winding wrist watch is also a mechanical watch. Energy is stored in this mainspring by turning (winding) a knob on the side. In a mechanical watch, gears are turned by a spiral spring. But we don’t know for sure… Mechanical Watch Why? Given their very small size, no ‘antenna’ effect, metal enclosure (or partial), and EMP variables themselves – the watch may continue to function. There is also opinion that a modern solar powered watch and/or one with digital features ‘may’ still work afterwards. While no one knows for sure (thankfully it hasn’t happened yet!), a kinetic mechanical winding (or automatic self winding) wrist watch will certainly work after EMP. Will an EMP (electromagnetic pulse) affect a wrist watch? Will your watch still work?
