The black hard coating on the stainless steel case transformed the watch. It gives it a sportier yet an understated look. It makes the watch less formal than its other brothers. The all-black finishes also perfect for one that searching for that stealthy look. On top of the dark tone, a pop of orange color on the indices and the minute hand-balances things up.

What makes the watch more unique is its Lumibrite, Seiko’s luminous paint that makes sure legibility in the dark. While usually, it’s in green when lit up, Lumibrite on this one is atypical as it has an orange color. Protecting the dial is a sapphire crystal, for peace of mind as its more scratch-resistant than a mineral crystal.

The case of the Sumo is very popular because of its design. The peculiar shape is bulky yet still comfortable to wear. It’s a big watch with a 45 mm case. However with a 52.5 mm lug to lug it will still fit most wrists. The Seiko SPB125 is also thinner than the original Sumo that launched in 2007. The watch is only 12.9 mm thick compared to the original 13.5 mm.
