Seiko Premier Kinetic Perpetual SNP159 SNP159P1 SNP159P 100M Men’s Watch

The perpetual calendar is not something incredibly complex or expensive; it’s not any straight-up quartz either! It’s a quartz motor that charges through a winding rotor behind a solid case back. However, the watch is just jam-packed full of modes and functions, though it doesn’t show. It’s a pragmatic and cost-effective perpetual calendar watch that’s very much in line with Seiko’s mission for enhanced accuracy, for as much and as long as possible.
