Product Description
Field-Ready GMT for the Modern Explorer
The Seiko SSK025 brings GMT functionality to the 5 Sports Field Series for the first time, combining rugged field watch aesthetics with dual-timezone capability. With its all-black hard-coated case and bold Arabic numerals, this is a watch built for adventure that tracks two time zones simultaneously.
Design & Dial
The black dial features bold luminous Arabic numeral hour markers and a 24-hour GMT scale on the inner chapter ring for easy second-timezone reading. The prominent five-sided GMT hand in red stands out clearly against the dark dial, ensuring instant legibility. LumiBrite treatment on hands and indices provides exceptional low-light visibility for field conditions.
Movement & Performance
The Caliber 4R34 automatic movement powers the GMT complication with 24 jewels and approximately 41 hours of power reserve. It features hacking seconds for precise time setting and manual winding capability. The independently adjustable GMT hand makes setting a second time zone quick and intuitive.
Case & Build
The 39.4mm stainless steel case features a hard coating in black that enhances both durability and aesthetics. At 13.6mm thick with a 47.9mm lug-to-lug, it commands wrist presence while remaining comfortable. A curved Hardlex crystal protects the dial, while the screw-down exhibition caseback lets you admire the 4R34 movement. Water resistance to 100 meters handles outdoor conditions with confidence.
Strap & Comfort
The single-pass black leather strap provides a comfortable, secure fit with a military-inspired aesthetic that complements the field watch design. The 20mm lug width offers plenty of aftermarket options for personalization.
