The SPB177 is a refreshing take on the Seiko Sumo series. The watch features a classic green dial and bezel. The Seiko Sumo is a relatively new design in the legendry Seiko dive watch catalog, but is already a fan favorite. The reason the nickname sumo came to be really isn't known, but that doesn't matter. What matters is that this is an all round great Seiko watch. The Ice Diver series celebrates adventure and shows that their watches can stand the harshest environments.

The heart of any watch is the movement. While a watch might look awesome, it is the movement that tells us if it is a great watch. Seiko is one of the largest vertically integrated watch companies. They make quality affordable watches all the way to the high end Grand Seiko watches. At the heart of the SPB177 is the Seiko movement the Caliber 6R35. The fantastic part of the 6R35 is that it has a 70 hour power reserve. Most automatic watches only go up to 40 hours and if you forget to wear your watch for a day or two you will have to reset it. The 70 hours gives you an extra day.
