Key Features
- Silver Dial with Luminous Markers: The silver dial provides a clean, legible backdrop that enhances readability throughout the day. Applied hour markers are treated with luminous material, allowing for clear timekeeping in low-light environments such as dimly lit rooms or nighttime settings.
- Two-Tone Stainless Steel & Yellow Gold Band: The bracelet features alternating links of brushed stainless steel and polished yellow gold, creating a sophisticated contrast that elevates its visual appeal. This combination ensures the watch pairs well with both casual and formal attire, offering flexibility across occasions.
- Automatic Chronometer Movement: Powered by a self-winding mechanical movement, this watch eliminates the need for battery replacements while maintaining consistent accuracy. The chronometer certification confirms it has undergone stringent testing and meets high standards for timekeeping precision.
- 100 Meters Water Resistance: Rated for water resistance up to 100 meters (330 feet), this watch is suitable for swimming, snorkeling, and surface water activities. It is not designed for scuba diving or high-impact water sports, but it provides peace of mind during everyday exposure to moisture.
- Scratch-Resistant Sapphire Crystal: The front crystal is made from synthetic sapphire, one of the hardest transparent materials available, offering superior resistance to scratches and impacts compared to standard mineral glass.
- Fixed Bezel Design: The unidirectional fixed bezel maintains a clean, streamlined profile while contributing to the watch’s structural durability. Its polished finish complements the overall two-tone aesthetic.
- Solid Caseback: The solid stainless steel caseback protects the internal movement from dust and moisture, ensuring long-term reliability and shielding the intricate mechanics from external elements.
