Watch Description
Watch Description
The Seiko 5 Sports Automatic GMT SBSC021 is a highly versatile and functional men's timepiece, affectionately nicknamed the "SKX GMT" by enthusiasts for its heritage design inspired by the classic SKX series. This watch is a Japanese Domestic Market (JDM) model. The watch is powered by Seiko's new in-house Automatic GMT movement (Caliber 4R34) with 24 jewels and a power reserve of approximately 41 hours. It allows you to track a second time zone with a dedicated GMT hand. The timepiece measures a bold 42.5mm in case diameter and is built with a sturdy stainless steel case. The dial is a refined black dial with contrasting luminous hands and markers, complemented by a rotating bi-color black and gray bezel insert to distinguish between night and day hours. It is protected by a durable Hardlex crystal and offers a water resistance rating of 100 meters (10 Bar). It is completed by a new Jubilee-style stainless steel bracelet, offering a comfortable and high-quality feel.
