Seiko SQ100 or 100M or 10 BAR means "Seiko Quartz Water resistant for Snorkelling (maximum)"



There are thousands of Seiko SQ100 and 100M watch models (SQ = Seiko Quartz).

If it doesn't say Chronograph, Kinetic or Automatic on the dial, then it will be a normal Quartz watch

Otherwise please look down the "Ordered List" for the calibre number that is on the rear case.
