Seiko Essentials Tank Quartz SWR107

The Seiko SWR107 is part of the Essentials line’s rectangular family—the watches the collector community simply calls the Seiko Tank. It’s an honest homage to the 1917 Cartier silhouette, executed with the restraint and build quality Seiko has been refining for more than a century. At 19.6mm across and just 6.1mm thick, this is small-wrist territory, and it sits as flat as a watch this shape should.
