1 Answer

What the numbers on the back of a Seiko watch mean varies. Seiko watches may be engraved with a serial number, model number or combination of the two. Some timepieces also display a caliber number, telling you about the watch's movement. You can cross-reference the numbers on your timepiece with information published in trusted online databases to determine what the markings on your watch mean.
