Key Features

• Eco-Drive Technology: Powered by any light source—natural or artificial—this watch eliminates the need for battery replacements. The E168 base movement ensures accurate timekeeping while reducing environmental impact, making it a sustainable choice for the modern adventurer. Whether you’re in sunlight or under indoor lighting, the watch charges efficiently and maintains power for months in darkness.
• ISO-Compliant Diving Watch: Built to meet rigorous international diving standards, this watch is water-resistant up to 200 meters (660 feet), making it suitable for recreational scuba diving. Its robust construction and precise engineering ensure safety and reliability at depth, giving divers confidence in challenging underwater conditions.
• One-Way Rotating Bezel: The unidirectional rotating bezel allows divers to track elapsed time safely, preventing accidental overestimation of dive duration. Its precise, tactile movement ensures accurate timing during underwater activities, a critical feature for dive safety and mission planning.
• Luminous Hands and Markers: Equipped with high-visibility luminous elements on the hands and hour markers, this watch ensures excellent readability in low-light or dark underwater environments. The glow lasts for hours after exposure to light, providing continuous visibility during night dives or in murky waters.
• Two-Tone Stainless Steel Construction: Crafted from durable stainless steel with a sleek silver-tone finish and two-tone accents, the case and bracelet offer both strength and refined style. The 45mm round case is designed for visibility and comfort, while the mineral crystal resists scratches and maintains clarity over time.
• Safety Fold Over Clasp with Push Buttons: The secure clasp ensures the watch stays firmly in place during active use, while the push-button release allows for easy and safe adjustment. This feature enhances both comfort and safety, especially during high-movement activities like swimming or diving.
