Belmont 300 Automatic

Duckworth Prestex Belmont 300 Automatic D328-03 ST

The Duckworth Prestex Belmont 300 Automatic D328-03 ST is a high-performance luxury dive watch that combines professional specifications with timeless sports watch styling. Designed with inspiration drawn from vintage cushion-case dive watches, this automatic timepiece delivers exceptional functionality while maintaining a refined contemporary aesthetic. The 42mm brushed 316L stainless steel case provides outstanding durability and a commanding wrist presence, while its impressive 300 metre water resistance ensures genuine capability for diving and aquatic adventures. The blue fumé dial immediately captures attention with its signature Belmont wave-textured finish, adding depth and visual sophistication to the overall design. Contrasting accents on the seconds hand and hour markers inject vibrant character, while BGW9 Super-LumiNova on the hands, indices, and triangular bezel marker guarantees optimal visibility in low-light environments. Built as a true automatic diver watch, the Belmont balances robust engineering with elegant finishing, making it equally suitable for professional use and everyday wear.

At the heart of the watch is the dependable Miyota 9039 automatic movement, selected for its proven precision, reliability, and smooth operation. Offering a 38-hour power reserve, this movement provides consistent performance for demanding lifestyles. The dial is protected beneath a double-domed sapphire crystal featuring anti-reflective coating on the underside, ensuring exceptional clarity and long-lasting scratch resistance. A screw-down crown and stamped screw-in case back further enhance durability and water resistance. This version is fitted with a premium brushed stainless steel three-link bracelet featuring a folding clasp and ratcheted instant extension system for superior comfort and practicality. Quick-release spring bars allow easy bracelet changes for enhanced versatility. Combining British watchmaking heritage, premium dive watch engineering, and refined detailing, the Duckworth Prestex Belmont 300 Automatic D328-03 ST is an exceptional luxury sports watch designed for collectors and enthusiasts who value performance, craftsmanship, and enduring style.
