Ensuring that this watch stays strapped to your wrist is a very secure double-button release folding clasp. First Class Watches Limited acts an authorised credit broker and not a lender who offers credit from different providers, including PayPal Credit, Klarna and Secure Trust Bank PLC trading as V12 Retail Finance. If you require an extra large bracelet or you are in need of additional links these may be supplied at an additional cost.

And lastly, as a project watch that you may use to learn how to customize (“mod”) Seiko sports models, the SBSA005 is also irreplaceable. While it’s stamped steel and perhaps a bit “jangly”, the clasp will not open unless the two buttons are depressed so there are no concerns of this watch flying off your wrist if you’re engaging in some sort of extreme activity.Powering the SBSA005, and visible through the crystal caseback, is a self-winding Seiko 4R36 caliber. This being the Made in Japan model, there is some small print below the 6 o’clock index that denotes this.

I’d argue that, when devising the 5 Sports collection, Seiko began with a subtly-colored piece such as this SBSA005 and then expanded into other bracelets, dial/bezel colors, case coatings and more. Considering this, I don’t think it’s unfair to say that this watch is the epitome of the Seiko 5 Sports collection.

Sitting atop the case is a unidirectional steel bezel that is textured on its outer perimeter to aid in rotating the bezel. Our watch sizing tool is incredibly easy to use, allowing you to manually add or remove bracelet links to achieve the perfect bracelet size.
