Eco-Drive: powered by light
Eco-Drive technology harnesses natural and artificial light to power the watch, eliminating the need for regular battery replacements.

The four-level indicator makes it easy to monitor the available charge.

The World Time function allows you to select local time across 24 time zones, making this model a practical companion for travellers. The perpetual calendar automatically manages the date, day of the week and leap years up to 2100.
The Moon at the heart of technology
The Moon Phase – Luna Program automatically calculates and updates the lunar phase display based on the watch's date and time. You can select the Moon representation for the Northern or Southern Hemisphere and manually calibrate the lunar phase. The dial also features the day of the week, a 24-hour indicator and a date display, bringing together practical information in a functional and harmonious layout.
Grey steel and refined details
The stainless steel case with a dark grey coating is paired with a matching bracelet, creating a cohesive and distinctive look. Rose gold-tone details bring warmth to the dial and enhance its contemporary character. The flat sapphire crystal protects the dial, while luminous hands and markers improve readability in low-light conditions. Measuring 42 mm in diameter and 10.7 mm in thickness, and weighing approximately 137 grams, the watch has a solid presence on the wrist. Water resistance to 10 bar completes a timepiece designed for reliable everyday wear.
