Key Features

• Octagonal Stainless Steel Case: The robust 41mm case is crafted from polished stainless steel and features a signature octagonal shape, a defining element of the Defy collection. Its geometric form provides both structural strength and a bold visual identity, standing out in any watch collection.
• 14-Sided Bezel: A defining characteristic of the original Defy design, the multi-faceted bezel adds a technical and industrial edge to the watch. Each of the 14 sides is precisely machined for a sharp, architectural finish that catches the light and enhances the watch’s three-dimensional appeal.
• Deep Red Gradient Dial: The dial showcases a rich, deep red hue that transitions subtly from dark at the edges to a slightly lighter tone toward the center, creating a dynamic visual depth. This gradient effect gives the watch a modern yet timeless look, perfect for both formal and casual settings.
• Steel Ladder Bracelet: The bracelet features a unique ladder-style link design that combines flexibility with durability. Its brushed and polished finishes complement the case, offering a comfortable fit and a distinctive aesthetic that echoes the watch’s industrial inspiration.
• ELITE 670 Automatic Movement: Developed and manufactured in-house by Zenith, this self-winding movement delivers reliable performance with a 50-hour power reserve. It features hours, minutes, and seconds functions with a date display, all operating with precision and long-term stability.

Important Notes

This timepiece comes in its original packaging, including a Zenith presentation box and warranty documentation. As a mechanical watch, it should be serviced periodically by an authorized technician to maintain optimal performance. While water-resistant to 100 meters, it is not designed for high-impact water sports or deep diving. The stainless steel bracelet may require occasional cleaning to preserve its finish. Always ensure the crown is fully pushed in or screwed down (if applicable) to maintain water resistance. Avoid exposing the watch to strong magnetic fields, extreme temperatures, or harsh chemicals.
