The Seiko 5 Sports SSK001K1 is a highly versatile automatic GMT watch that combines Seiko's iconic SKX-inspired sports design with practical dual-time functionality. Often known as the Seiko 5 Sports “Boy GMT”, this model features a striking black dial, a two-tone black and grey 24-hour bezel, and a classic five-row stainless steel bracelet. It is an excellent choice for everyday wear and international travel.
At the heart of the SSK001K1 is Seiko's Calibre 4R34 automatic GMT movement, offering both automatic and manual winding and approximately 41 hours of power reserve. The dedicated 24-hour GMT hand allows you to track a second time zone at a glance, while the magnified date display adds useful everyday functionality.
