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 powered by a Seiko NH35 automatic movement and is priced starting at $269. Overall, owners and reviewers view the Audaz Reef Diver positively as a robust tool watch with a clear dial and strong water resistance for its price.

Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.
