Understanding Seiko Watch Movements
Automatic Watches
Automatic Seiko watches use mechanical movements powered by a mainspring that can be wound through wrist motion. They need sufficient stored energy to keep running. Automatic movements are found in many Seiko 5 Sports, Presage, and Prospex models.
Quartz Watches
Quartz watches use an electronic movement regulated by a quartz crystal. They are generally known for accurate timekeeping and convenience. Seiko offers quartz models across several collections.
Solar Watches
Seiko Solar watches convert light into electrical energy stored in a rechargeable cell, reducing the need for routine battery replacement. Solar technology is available in selected collections, including Prospex and Coutura.
GPS Solar Watches
Seiko Astron GPS Solar watches combine light-powered operation with GPS satellite reception. Depending on the model and reception conditions, they can synchronize time and support time-zone adjustments.

4. Features and Functions
Depending on the model, Seiko watches may include chronographs, GMT functions, rotating bezels, date displays, and varying water-resistance ratings. Check each product specification.
