The watch’s specs are pretty solid as well. It’s powered by the 4R35 caliber, previously used on Seiko’s Prospex models and more recently the Seiko 5 Sports series, and it is visible through the caseback, something we don’t usually see as well from the brand (mostly in Presage models and above). With a healthy 41 hour power reserve, this is a fun daily beater to get your hands on. In addition, the metal bracelet version comes with a single-fold, three-part deployment strap with an easy adjust function, which means you can tighten up or loosen the bracelet on your own, without the need for additional tools.
