Key Features
- Self-Winding Mechanical Movement: Powered by the Calibre 2824, this movement ensures consistent accuracy and eliminates the need for manual winding.

- Approximately 38-Hour Power Reserve: Once fully wound, the watch can run for up to 38 hours, offering dependable performance even if not worn for a day or two. This makes it practical for daily use and short periods of inactivity, ensuring that the watch remains accurate and ready to wear without constant attention. Whether you’re taking a day off or traveling, the power reserve maintains functionality and convenience.
- Elegant Blue Dial with Diamonds: The deep blue dial adds a touch of refinement, while the diamond hour markers enhance its luxurious appeal. The contrast between the dial and markers ensures clear legibility while maintaining a sophisticated aesthetic. The rich hue of the dial complements the sparkling diamonds, creating a balanced and visually striking face that catches the light beautifully in various settings.
- 38mm Case Size: The mid-sized case strikes a balance between presence and comfort, fitting well on most men’s wrists. Its proportions make it versatile for both dress and everyday wear, offering a modern presence without overwhelming smaller wrists. The case dimensions are thoughtfully designed to appeal to a wide range of wearers who value both style and practicality.
- Classic Date Function: The date display at the 3 o’clock position adds practical functionality without disrupting the clean, balanced design of the dial. It’s a subtle yet useful feature for daily time management, allowing the wearer to stay organized with minimal visual distraction. This functional detail enhances usability while preserving the watch’s elegant symmetry.
