Key Features
- Green Dial with LumiBrite Markers: The round green dial provides a fresh, contemporary look while maintaining a professional tone. The minimalist design emphasizes clarity, with LumiBrite-coated hour markers and hands that glow brightly in low-light environments, ensuring easy readability at night or in dimly lit spaces. This feature enhances both safety and convenience for wearers who rely on their watch in various lighting conditions.
- Solar-Powered Movement: Powered by Seiko’s reliable V172 solar caliber, this watch converts both natural sunlight and artificial indoor light into energy, stored in a rechargeable cell. This eliminates the need for regular battery replacements and supports long-term accuracy and sustainability. A full charge can power the watch for several months, even in complete darkness, making it an eco-friendly and hassle-free choice.
- Stainless Steel Case and Bracelet: Crafted from two-tone stainless steel, the case and matching bracelet combine brushed and polished finishes for a refined, dimensional look. This durable material resists corrosion and maintains its appearance over time, while the bracelet offers a comfortable, secure fit with a fold-over clasp. The design strikes a balance between robustness and elegance, suitable for everyday wear and special occasions alike.
- Hardlex Crystal: The dial is protected by a Hardlex crystal, a proprietary Seiko material known for its excellent scratch resistance and clarity. While not as hard as sapphire, it offers reliable protection against everyday scuffs and impacts, ensuring the watch face remains legible and presentable through years of use.
- Date Display: A discreet date window at the 3 o’clock position adds practical functionality, helping you stay on track with appointments and schedules. The placement is integrated smoothly into the dial design, preserving the watch’s clean and uncluttered aesthetic.
- 100-Meter Water Resistance: Rated for 100 meters (10 bar), this watch is suitable for swimming, showering, and other water-related activities. It can withstand splashes, rain, and brief submersion, making it a reliable choice for active lifestyles. However, it is not designed for high-impact water sports or scuba diving, and the crown should not be operated underwater.

Important Notes
While the watch is water-resistant up to 100 meters, it should not be used for scuba diving or high-pressure water sports. Avoid pressing the crown or buttons while submerged. The Hardlex crystal offers solid scratch resistance but may show signs of wear over time with heavy daily use. For specific warranty coverage and service options, customers should consult Seiko’s official warranty policy. The watch arrives in original Seiko packaging and is intended for men’s wear.
