MIDO Belluna Sunray – Swiss Automatic Watch for Men – Blue

Product Overview

The MIDO Belluna Sunray is a Swiss automatic watch designed for men who value precision, heritage, and understated luxury. At its heart lies a striking blue sunray dial that draws inspiration from the iconic dome of London’s Royal Albert Hall—a subtle nod to architectural grandeur translated into horological form. The radiant finish shifts in tone depending on the light, offering a dynamic visual experience that captures attention without overwhelming. Encased in a 42.5mm stainless steel body with alternating polished and satin finishes, the watch strikes a refined balance between presence and wearability. Its design is both contemporary and timeless, making it equally at home in a boardroom or at a formal dinner.

Powered by the Mido Caliber 80 automatic movement, this timepiece delivers reliable performance with minimal maintenance. The movement is entirely mechanical, eliminating the need for a battery, and features an impressive 80-hour power reserve—meaning it keeps accurate time even after three days off the wrist. For those who appreciate the inner workings of fine watches, the transparent sapphire crystal case-back offers an unobstructed view of the oscillating rotor and finely finished components. This blend of aesthetic elegance and mechanical sophistication makes the Belluna Sunray a compelling choice for both everyday wear and special occasions.

Key Features

• Blue Sunray Dial – The dial features a distinctive sunburst pattern in deep blue, mirroring the curvature of the Royal Albert Hall’s cupola. This design element not only adds visual depth but also reflects light beautifully, enhancing readability and elegance throughout the day.
• Swiss Automatic Movement (Caliber 80) – Developed by Mido, this in-house movement ensures consistent accuracy and longevity. Its 80-hour power reserve reduces the frequency of manual winding, making it ideal for regular wear and travel.

• 42.5mm Stainless Steel Case – The case combines polished and brushed surfaces, creating a refined contrast that highlights the watch’s contours and enhances its premium feel. The size is well-suited for medium to larger wrists, offering a confident presence without being overly bulky.
