The Seiko 5 Sports SRPK87K1 is a great, versatile sports watch with a modest contemporary size.
It's a great watch and a true all-rounder with 100m water resistance and an elegant an comfortable 37.4mm case (excluding crown). The dial is protected by Hardlex crystal and the case and bracelet are both stainless steel.
Under the hood is the mechanical (automatic) Seiko in-house Cal. 4R36 movement, with a day (in English and Japanese) and date indicator at 3 o'clock.
