Here we have a 2024 DOXA SUB 300β "Beta" Sharkhunter Ceramic, reference 830.20.101ND.20. This stealthy Swiss dive timepiece features a 42.5mm matte black ceramic case built on a lightweight titanium case, showcasing the brand’s historic cushion-shaped silhouette with a modern, high-tech twist. The case features smooth, non-reflective micro-blasted surfaces that emphasise its technical purpose, offering an incredibly compact lug-to-lug length of 44.5mm and a slender thickness of 12mm, ensuring an exceptionally comfortable and ergonomic fit on the wrist. An 18K 3N gold screw-down crown and a solid titanium caseback contribute to a serious 300-metre water resistance. The standout feature of this model is the sophisticated matte black Sharkhunter dial, accented by 18K 3N gold hands and applied indexes, creating a striking, high-contrast luxury aesthetic. Framing the dial is DOXA's signature patented unidirectional rotating bezel, here crafted from 18K 3N gold and black ceramic to display the dual US Navy no-decompression dive table tracks. The iconic oversized minute hand and the hour markers are generously filled with Super-LumiNova for maximum low-light legibility. A date window is cleanly integrated at 3 o'clock, maintaining the tool-watch functionality. Protecting this stealthy diving instrument is a flat sapphire crystal with an internal anti-reflective coating. Inside beats the reliable automatic Sellita Calibre SW200-1, a premium Swiss workhorse featuring 26 jewels and a high-beat frequency of 28,800 vibrations per hour. This calibre is celebrated across the industry for its durability and ease of service, offering a 38-hour power reserve and hacking seconds for precise time-setting. The watch comes paired with a bespoke 20mm black FKM rubber strap and a black PVD-coated folding clasp featuring an integrated adjustable diving extension, anchoring this modern diver securely over a wetsuit or on the bare wrist. The strap is cut to size at 8.4 inches and can be cut smaller.
