The 48.5mm by 45.4mm case achieves its slim 11.9mm profile through the advanced Carbon Core Guard structure, encasing the module in carbon fiber-reinforced resin. Time tracking is further enhanced by a 1/100-second stopwatch, a countdown timer, and a world time function covering 38 cities.

The bio-based resin construction provides exceptional shock absorption while offering a highly breathable, ergonomic fit for all-day wear. Its flexible strap adapts easily to active environments, preventing discomfort during intense workouts or outdoor adventures. Furthermore, the inclusion of a high-brightness double LED Super Illuminator guarantees brilliant low-light visibility, making it a highly practical tool for nighttime use.
