Key Features

• Solar-Powered Movement with Radio Sync: Harnessing solar energy from ambient light or artificial sources, this movement charges the built-in rechargeable cell, eliminating the need for frequent battery replacements. Once fully charged, the watch automatically syncs to atomic time signals via radio waves (in supported regions), maintaining exceptional accuracy and adjusting for daylight saving time.
• Chronograph Functionality: Featuring three functional subdials, this model allows precise measurement of elapsed minutes, seconds, and hours. Whether timing workouts, cooking sessions, or coordinating team events, the chronograph adds practical utility to everyday routines.
• Sapphire Crystal Glass: A highly durable sapphire crystal protects the dial from scratches and everyday wear, ensuring long-term clarity and resistance to impact—ideal for active lifestyles.
• LumiBrite Luminescent Markers: Minimalist hour markers and hands glow in low-light conditions after exposure to light, enhancing visibility during nighttime activities or in dim environments without compromising the clean, understated dial design.
• Vibrant Red Genuine Leather Strap: Crafted from genuine leather, the strap offers comfort and breathability while adding a pop of color. The secure buckle closure ensures a snug fit, and the red finish complements the watch’s sporty-chic character.
• Precision Stainless Steel Case: Built with corrosion-resistant 40mm stainless steel, the case maintains its lustrous finish over time and provides robust protection for the intricate internal mechanics.
• 100-Meter Water Resistance: Rated for immersion up to 100 meters (10 bar), this watch withstands swimming, rain, and water-based activities, making it suitable for regular use near water.

Important Notes

The watch includes an LR44 battery to power the solar cell and luminescent elements. To maintain optimal performance, expose the watch face to light regularly—direct sunlight or bright indoor lighting is sufficient. While rated for 100 meters of water resistance, it should not be used for high-pressure water sports such as jet skiing or deep-sea diving. Customer reviews highlight satisfaction with the watch’s accuracy and durability, though some users note that leather straps may benefit from occasional conditioning to preserve color and suppleness over time. The product ships in standard packaging with no additional accessories beyond the included battery.
