Duckworth Prestex Belmont 300 Automatic D328-05 ST

The Duckworth Prestex Belmont 300 Automatic D328-05 ST is a professional-grade automatic dive watch engineered for enthusiasts who value robust performance, premium construction, and refined contemporary styling. Inspired by classic compressor and cushion-case dive watches, this luxury sports watch combines vintage diving heritage with modern British watchmaking expertise. The durable 42mm cushion-shaped case is crafted from brushed 316L stainless steel and delivers an impressive 300 metre water resistance, making it a true professional diver watch built for demanding underwater conditions. The striking fumé dial features the distinctive Belmont wave pattern, creating impressive visual depth while reinforcing the watch’s maritime character. Contrasting accents on the sweep seconds hand and hour markers inject sporty energy into the design, while BGW9 lume on the quarter Arabic indices, polished steel hands, and triangular bezel marker guarantees exceptional legibility in low-light and underwater environments. Combining technical capability with refined finishing, the Belmont 300 Automatic offers exceptional versatility as both a luxury dive watch and an everyday automatic sports watch.

At the heart of the Duckworth Prestex Belmont 300 Automatic D328-05 ST is the highly reliable Miyota 9039 automatic movement, chosen for its dependable precision and smooth performance. Offering a 38-hour power reserve and daily tolerance of -10/+30 seconds, the movement ensures reliable operation across active lifestyles. The dial is protected beneath a double-domed sapphire crystal with anti-reflective underside coating, delivering excellent clarity and superior scratch resistance. Additional professional specifications include a screw-down crown, stamped screw-in case back, and premium brushed stainless steel three-link bracelet with folding clasp and ratchet extension system for enhanced comfort and functionality. Quick-release spring bars allow effortless bracelet changes for added versatility. Individually quality checked before sale and presented with an orange microfibre polishing cloth and premium presentation case, every Belmont reflects exceptional craftsmanship and attention to detail. Backed by a 2-year warranty, this luxury automatic diver combines British design heritage, professional dive watch engineering, and timeless sports watch styling for collectors and enthusiasts alike. :contentReference[oaicite:1]{index=1}
