SEIKO Prospex Alpinist GMT Blue | SPB377
The SEIKO Prospex Alpinist GMT Blue is the perfect combination of style and functionality. Its stainless steel construction ensures durability, while its 42mm face is encased in scratch-resistant sapphire crystal for reliable protection. The lumibrite hands and markers make the time easy to read, and its GMT function allows for seamless tracking of multiple time zones.
The new Calibre 6R54, which has a power reserve of three full days, powers the new Seiko Prospex Alpinist Mechanical GMT. The 24-hour display on the bezel and the 24-hour hand with red tip guarantee the legibility of the GMT function.
