The Watch
A refined 31mm automatic watch pairing a deep black dial with classic Roman numerals and a polished two-tone gold finish.
The smaller 31mm case creates an elegant, comfortable profile, while the black dial and gold-tone Roman numeral markers give the watch a timeless, high-contrast look. The Jubilee-style bracelet completes the design with a smooth, refined finish that works beautifully for both everyday and dress wear.
Powered by an NH05 automatic movement, the watch is protected by sapphire crystal for lasting clarity and everyday scratch resistance.
