Second time zone always in view

The integrated GMT function allows the display of a second time zone via an additional 24-hour hand. This makes the SPB379 ideal for frequent travelers and anyone who regularly works with different time zones.

The clear design ensures quick and intuitive readability of the various time displays.

Automatic movement with 72-hour power reserve

Inside, the modern Seiko caliber 6R54 with automatic winding and additional manual winding function operates. The generous power reserve of up to 72 hours ensures high everyday practicality and reliable performance even after several days without wearing.

Thanks to the hacking seconds feature, the watch can also be set with exceptional precision.

High-quality materials for demanding use

The stainless steel case with Super-Hard-Coating reliably protects the watch from the stresses of daily use. The domed sapphire crystal with inner anti-reflective coating provides a clear view of the dial and emphasizes the high-quality character of the model.

LumiBrite on hands and indices ensures excellent readability in darkness and low light conditions.

Outdoor functions with true Alpinist DNA

The internal compass ring is one of the traditional features of the Alpinist series and supports orientation during outdoor adventures. The equipment is complemented by a screw-down crown, a screw-down exhibition case back, and water resistance up to 20 bar.
