Movement & Engineering
The movement advances both the day and date through dedicated calendar mechanisms. A long reserve supports weekend autonomy, and the automatic rotor replenishes energy during wear. The concealed clasp maintains the continuous appearance of the bracelet around the wrist.
Design & Wearing Experience
The blue dial introduces strong colour while the white-gold exterior remains visually cool and discreet. A fluted bezel adds fine light reflections, and the full day aperture creates a distinctive symmetrical element at the top of the dial.

Care & Maintenance
White gold should be cleaned with a soft non-abrasive cloth. Avoid chlorine, harsh chemicals and contact with harder jewellery. Do not change the day or date during the movement’s calendar-transition period.
Water-resistance notice: the stated rating assumes that the crown, pushers and seals are correctly secured and that the watch has passed a recent pressure test. Water resistance can decrease over time and should be checked periodically.
