Powered by solar energy and equipped with radio synchronization, this watch ensures accurate timekeeping without the need for frequent battery changes. Built for reliability and elegance, it’s a strong choice for watch enthusiasts seeking a durable, low-maintenance accessory.

Key Features

• Solar-Powered Movement with Radio Sync: The watch uses Seiko’s advanced solar technology, harnessing light from any source—indoor or outdoor—to power the movement. With radio synchronization, it automatically adjusts to atomic clock signals for exceptional accuracy, ensuring you’re always on time, even when traveling across time zones.
• Chronograph Functionality: Equipped with three subdials, this timepiece allows precise measurement of elapsed time in seconds, minutes, and 1/20th-second increments. Whether timing a workout, tracking a meeting, or managing daily tasks, the chronograph adds practical utility without compromising elegance.
• Sapphire Crystal: The dial is protected by scratch-resistant sapphire crystal, offering superior durability and optical clarity compared to standard mineral or acrylic glass. This ensures the watch face remains pristine and legible over years of wear.
• LumiBrite Markers: Minimalist hour markers and hands are treated with Seiko’s proprietary LumiBrite material, which glows brightly in low-light conditions. Unlike traditional luminous paints, LumiBrite charges quickly under any light and provides long-lasting visibility without requiring external light exposure.
• Black-Ion Finished Case: The stainless steel case features a sleek black-ion (PVD) finish that resists scratches and fading while adding a modern, sporty edge. This durable coating maintains its deep black luster even with daily use.
• Genuine Leather Strap: The black leather strap is crafted for comfort and longevity, offering a classic look that complements the watch’s overall design. Its smooth texture and secure buckle ensure a comfortable fit for all-day wear.
• 100-Meter Water Resistance: Rated for 100 meters (10 bar), this watch is suitable for swimming, snorkeling, and other water-related activities. It can withstand splashes, rain, and brief submersion, though it is not designed for deep diving or high-impact water sports.
