It features a 45mm 316L stainless steel case, sapphire crystal, Super-LumiNova C3, and 300m water resistance. One owner notes it is a large, heavy watch. The Audaz Reef Diver is available with a Seiko NH35 automatic movement starting at $269. On balance, owners and reviewers view the Audaz Reef Diver positively for its dependable tool-watch design and robust specifications at its price point.
Owners widely praise the Bremont S502 Jet for its attractive full-stealth black DLC treatment and 'black & tan' aesthetic, noting the burnt orange GMT hand enhances legibility against the beige lume. The watch is described as a handsome and cool tool watch suitable for hard wear, with a DLC-coated stainless steel case and ceramic bezel. Some owners prefer the NATO strap for its aesthetic integration with the PVD metalwork, while others favor the original black rubber strap for comfort and fit. The Bremont S502 is powered by the Bremont BE-93-2AE automatic movement. Overall, owners and reviewers rate the Bremont S502 highly for its stealthy design and functional tool-watch appeal.
