Key Features

• Solar-Powered Movement with Radio Sync: The watch utilizes SEIKO’s advanced solar technology, converting both natural and artificial light into energy to power the movement. This eliminates the hassle and cost of battery replacements. Additionally, the radio sync feature automatically receives atomic time signals, adjusting for time zone changes and daylight saving time to maintain exceptional accuracy—ideal for frequent travelers or those who demand precision.
• Three-Hand Chronograph Function: Equipped with three subdials, the chronograph tracks elapsed time in seconds, minutes, and 1/20th of a second increments. This functionality is perfect for timing athletic events, cooking, work intervals, or any activity requiring precise measurement. The pushers on the side of the case allow for easy start, stop, and reset operations.
• Sapphire Crystal with Anti-Reflective Coating: The watch face is protected by a scratch-resistant sapphire crystal, one of the hardest materials used in watchmaking. The anti-reflective coating reduces glare from sunlight or artificial lighting, ensuring the dial remains clearly visible in all conditions—from bright outdoor settings to dimly lit rooms.
• LumiBrite Luminous Markers: The hour markers and hands are coated with SEIKO’s proprietary LumiBrite material, which charges quickly when exposed to light and provides a bright, long-lasting glow in the dark. This enhances readability during nighttime or in low-light environments, such as early morning runs or evening commutes.
• 100-Meter Water Resistance: With a water resistance rating of 100 meters (10 bar), this watch is suitable for swimming, snorkeling, and other water-based activities. It’s built to withstand splashes, rain, and brief submersion, making it a dependable companion for active lifestyles—though it’s not recommended for scuba diving or high-impact water sports.
• Stainless Steel Case and Bracelet: Crafted from high-grade stainless steel, both the case and bracelet offer excellent resistance to corrosion, wear, and daily abrasions. The polished and brushed finishes create a modern, sophisticated look that complements casual and formal attire alike. The bracelet includes a secure three-fold clasp with a push-button release for comfort and ease of use.

For detailed warranty information, please refer to the manufacturer’s official website.
