The Seiko 5 Sports SRPL33K1 (SRPL33) HUF Limited Edition is a great, versatile sports watch. It's a true all-rounder with 100m water resistance, rotating bezel and a comfortable 42.5mm case (excluding crown) and a modest 46mm lug to lug distance. The great vintage-style dial is protected by Hardlex mineral glass and under the hood is the mechanical (automatic) Seiko in-house Cal. 4R36 movement. This model pays tribute to the amazing Kamen Rider model from the 60s and does so in great fashion.
