You’ll see the balance wheel oscillating in real time, turning each glance at your wrist into a moment of mechanical fascination. It’s a design that celebrates transparency and craftsmanship.
• Sapphire Crystal Glass: The watch face is protected by genuine sapphire crystal, renowned for its exceptional scratch resistance and optical clarity. This high-performance material ensures the dial remains clear and unmarred, even after years of daily use.
• Ostrich Leather Strap: Crafted from genuine ostrich leather, the strap delivers a unique texture and rich visual appeal. Known for its softness and durability, ostrich leather adds an exotic touch of luxury while remaining comfortable for extended wear.
• 50m Water Resistance: Rated for 50 meters (5 ATM), this watch can handle splashes, rain, and brief contact with water. It’s suitable for everyday environments, including handwashing and light outdoor activities, though it’s not intended for swimming or diving.
