Special Features

Edge-to-Edge Glass Architecture: The crystal extends across the entire face of the watch to the very edge of the case, creating a smooth, continuous surface that catches light in a unique, liquid-like fashion.

Minimalist 1/5th-Second Chronograph: Provides stopwatch functionality with a central second hand that sweeps in 0.2-second increments for up to 60 minutes, all while maintaining a clean, uncluttered look.

Tonal Aesthetics: The indices and sub-dials are designed to blend into the black dial, revealing themselves through a subtle interplay of textures rather than high-contrast colors.

Eco-Drive Sustainability: Powered by any light—natural or artificial—this timepiece is environmentally friendly and ensures reliable operation without the maintenance of a traditional battery.

12/24-Hour Time: Includes a dedicated sub-dial at the 9 o’clock position to easily distinguish between AM and PM hours.

Ultra-Slim Lugs: The case features a refined lug design that keeps the focus on the circular geometry of the watch head, enhancing its modern, jewelry-like presence.
