SEIKO Blueberry GMT SSK003

The Seiko SSK003 blends iconic dive watch styling with world-time functionality, famously known as Blueberry. Part of the Seiko 5 Sports GMT series, it features a striking blue dial with a contrasting black-and-blue bezel, often nicknamed the “Batman GMT.” Powered by Seiko’s reliable 4R34 automatic GMT movement, it lets you independently set a second time zone using the dedicated GMT hand — a feature usually reserved for higher-end watches.

Rugged yet stylish, with a solid stainless steel build, this is a perfect entry-level GMT watch and a favorite among enthusiasts for its value, design, and daily wearability.
