Key Features

• Six-Hand Chronograph with Calendar – This advanced quartz movement includes hour, minute, and second hands, along with three sub-dials for elapsed time measurement (1/20 second, 60 second, and 30 minute counters). The integrated calendar function displays the current date, helping you stay on track with appointments and schedules. The chronograph feature is ideal for timing workouts, cooking, or any activity requiring precise interval tracking.
• Black Ion-Plated Stainless Steel Case – The case is crafted from durable stainless steel and finished with a black ion-plated coating. This not only enhances the watch’s sleek, modern appearance but also increases resistance to scratches and everyday wear, ensuring the watch maintains its sharp look over time.
• Flat Mineral Glass Crystal – The dial is protected by a flat mineral glass crystal, which offers reliable scratch resistance and clarity. While not as hard as sapphire, mineral glass provides excellent durability for daily use and helps maintain visibility in various environments.
• Screw-Back Case – The secure screw-down case back enhances the watch’s structural integrity and contributes to its water resistance. This design helps protect the internal components from dust, moisture, and impact, supporting long-term reliability.
• Black Silicone Strap with 3-Piece Buckle Closure – The flexible silicone strap is both comfortable and resilient, designed to withstand sweat, water, and frequent use. The 3-piece buckle closure ensures a secure fit and allows for easy adjustment, accommodating a range of wrist sizes with confidence.
• 100-Meter Water Resistance – Rated for water resistance up to 100 meters (330 feet), this watch is suitable for swimming, snorkeling, and showering. It’s a dependable choice for water-based activities, though it is not designed for high-pressure diving or submersion beyond recreational limits.
