Whether you’re timing a workout, exploring underwater environments, or navigating daily challenges, this watch offers dependable performance, robust build quality, and a bold aesthetic that stands out without sacrificing functionality.

Key Features

• Solar-Powered Movement: At its core, the SSC927 is powered by SEIKO’s H851 solar caliber, which efficiently converts both natural sunlight and artificial indoor light into electrical energy. This innovative system charges the built-in rechargeable battery, ensuring continuous operation and eliminating the inconvenience and cost of regular battery changes. With sufficient light exposure, the watch can run for up to six months on a full charge, making it an eco-friendly and low-maintenance choice for everyday wear.
• Precision Chronograph Functionality: The watch features a fully functional chronograph capable of measuring elapsed time with high accuracy. Subdials display 1/100th of a second, 60 minutes, and 12 hours, supporting precise timing for sports, training sessions, technical tasks, or competitive events. The pushers are designed for smooth operation, allowing easy start, stop, and reset functions even during active use.
• 200-Meter Water Resistance: Built to meet ISO standards for diving watches, the SSC927 offers 200 meters (20 bar) of water resistance. This makes it suitable for swimming, snorkeling, and recreational diving. The screw-down crown and reinforced case back contribute to its water-resistant integrity, ensuring reliable performance in wet conditions.
• Stainless Steel Case and Bracelet: The 43.5mm stainless steel case is both durable and corrosion-resistant, designed to withstand daily wear and exposure to saltwater. The matching stainless steel bracelet features a secure three-fold clasp with a safety lock, providing a comfortable and adjustable fit for various wrist sizes. The polished and brushed finishes add a refined touch to its sporty design.
• LumiBrite Luminous Markers: For enhanced visibility in low-light or underwater conditions, the hour markers and hands are coated with SEIKO’s proprietary LumiBrite material. This non-radioactive luminous substance charges quickly under light and glows brightly in the dark, lasting significantly longer than traditional luminous paints.
• Date Display: A practical date window is positioned at the 3 o’clock mark, offering at-a-glance convenience without disrupting the clean, balanced layout of the red dial. The date changes instantly at midnight for accuracy.

Important Notes

While the watch is water-resistant to 200 meters, it is not intended for high-speed water sports such as jet skiing or scuba diving beyond recreational depths. Users should avoid pressing the chronograph pushers or crown while submerged to preserve the watch’s water-resistant seals. The Hardlex mineral crystal provides good scratch resistance and durability, though it may show signs of wear over time with heavy use; professional polishing can restore clarity if needed. For optimal performance, the solar charging system requires regular exposure to light—ideally a few hours of indirect sunlight or bright indoor lighting per week. When storing the watch for extended periods, keep it in a well-lit environment or use a watch winder with light exposure. The SSC927 comes in original SEIKO packaging, complete with an instruction manual and international warranty card for peace of mind.
