The Seiko 5 SRPJ37K1 is a great, versatile sports watch. It's a true all-rounder with 100m water resistance, unidirectional bezel and a comfortable 42.5mm case (excluding crown) and a modest 46mm lug to lug distance. The great utilitarian dial is protected by Hardlex mineral glass and the case has a durable black coating.
Under the hood is the mechanical (automatic) Seiko in-house Cal. 4R36 movement, with a day and date indicator at 3 o'clock. This movement is also visible through the display caseback window.
If you're looking for a great every day watch, look no further than this very cool Seiko 5!
