The Seiko automatic watch collection is actually powered by the 7S26 21 Jewel automatic movements. Seiko automatic watches power themselves by the movement of your body.

The SKX779K also known as the “Black Monster” by Seiko watches. It has gained popularity amongst Japanese dive watch enthusiasts and enjoys brisk sales to this day.

The Black Monster or “BM” for short, triggered my love for divers and mechanical watches. The main attraction of this watch is an extraordinary lume i.e. this watch has brightest lume. The scalloped bezel design and case combination was something I had not seen before in a watch. An interesting moment is when the sword-like hands hour and minute hands line up together on the dial. It resembles a rocket ship to many Monster aficionados. The watch itself, on rubber strap is quite light on the wrist.

The caseback is a mixed affair of polished and matte surfaces. Seiko’s famous “tsunami wave” symbol is engraved in the middle of the caseback. The screw-in crown is easy to handle, not fiddly at all and screws in quite effortlessly. It’s a bold watch and it’s not something that you see on anyone’s wrist every day. The bezel is smooth turning and has 120 fine graduations or clicks, with each click representing half a minute. This watch has a diameter 42mm without crown and 47 mm with crown. Lug-to-lug size is 48 mm. It’s thickness is 14 mm and lug width is 20mm. The 7s26 movement is fully automatic and there’s nothing that you need to do.

Probably the highlight of the Monster is the ultra sensitive LumiBrite, the non-radioactive luminous compound developed in conjunction with the Nemoto Corp of Japan. The name LumiBrite itself is patented by Seiko. It doesn’t take much light to excite the BM’s lume and will readily glow for 8 to 10 hours in the dark.
