White Opaline Dial with Motorsport-Inspired Details

At the centre of the design is a white opaline dial, offering a clean and highly legible foundation. Black lacquered indexes and distinctive shield-shaped quarter-hour markers create strong contrast, ensuring immediate readability in all conditions.

A red central seconds hand adds a dynamic focal point, while the black minute-scale flange frames the dial with functional clarity. The combination of red, green, and white accents reflects the visual language of racing instrumentation, reinforcing the watch’s performance-driven identity.

Green TH‑Polylight Bezel and Steel Construction

The 38mm sandblasted stainless steel case provides durability while maintaining a comfortable and wearable profile. Paired with a green TH‑Polylight bidirectional bezel, the watch introduces a bold, technical element that enhances both functionality and visual distinction.

The stainless steel bracelet completes the design, offering a secure fit with a folding clasp and a balance of strength and everyday comfort.

Solargraph Technology: Powered by Light

At the core of the watch is the Calibre TH50‑00 Solargraph movement, a light-powered quartz system engineered for efficiency and long-term reliability. By converting natural and artificial light into energy, the watch continuously recharges during daily wear.

A full charge provides extended autonomy, reducing the need for battery replacement and ensuring consistent, precise timekeeping with minimal maintenance.

Built for Everyday Performance

Designed for versatility, the watch offers 100 metres of water resistance, making it suitable for a wide range of environments. A sapphire crystal enhances durability and clarity, ensuring the dial remains protected and easy to read.
