Seiko SPB379J1 Prospex Alpinist GMT Black Automatic—the perfect companion for every adventure.

The new Alpinist GMT SPB379J1 is powered by the 6R54 automatic caliber, a 24-jewel movement operating at a frequency of 21,600 vibrations per hour. This mechanical movement provides a 72-hour power reserve, a daily accuracy of between +25 and -15 seconds, and the useful GMT function for tracking a second time zone.

The sturdy stainless steel case measures 39.45 mm in diameter and 13.55 mm in thickness, and features a screw-down crown, a transparent case back, and a screw-fixed bezel. The dial is protected by a domed sapphire crystal and is water-resistant up to 20 bar, making the watch suitable even for demanding conditions. With a lug-to-lug width of 20 mm, the design is crafted to offer a perfect balance between vintage style and modern functionality.

The black dial features LumiBrite-coated hour markers and hands for superior readability.

The watch is finished with a black leather strap, which matches the dial, and fastens to the wrist with a folding clasp featuring a release button.

Watch accompanied by official Seiko warranty and packaging.
