PSR B1509-58 - X-rays from Chandra are gold; Infrared from WISE in red, green and blue/max. A pulsar (from pulse and -ar as in quasar) is a highly magnetized, rotating neutron star or white dwarf, that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much like the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission.
Changing a Pulsar watch battery is a quick and easy chore. However, caution should be exercised not to damage the watch or void the warranty if the watch is new and purchased from an authorized dealer. Pulsar watches are part of the Japan-based Seiko Watch Company family with millions of Pulsars sold worldwide.
