Why We Love This Watch
Pre-owned Doxa Sub 300T Sharkhunter ref. 840.10.101.10 (2025) is a professional-grade dive watch built for extreme underwater performance. Its 42.5mm stainless steel case houses a black “Sharkhunter” dial under a scratch-resistant sapphire crystal with anti-reflective coating. Powered by a Swiss automatic movement with a 38-hour power reserve, it features hours, minutes, seconds, and date functions. Rated to 1,200 meters (120 ATM) and equipped with a patented unidirectional rotating bezel with integrated no-decompression dive calculator, helium release valve, and Super-LumiNova markers, this diver ensures optimal legibility and safety. Finished with a 316L stainless steel “Beads of Rice” bracelet with ratcheting wetsuit extension, the Sub 300T Sharkhunter combines rugged durability with iconic Doxa design.
