Owners praise the Oceaneva 6000m Deep Marine Explorer VI Grade 5 Titanium for its tank-like build and impressive specifications, with one owner noting it keeps time very well. Reviewers highlight its extreme 6000m water resistance and value, particularly at its pre-order price of $899 USD. The 44mm case with an 18.2mm thickness and a 38-hour power reserve are noted specifications. Overall, owners rate the Oceaneva 6000m Deep Marine Explorer VI Grade 5 Titanium highly for its substantial feel and impressive specifications at its price point.
The Seiko Prospex Sea The Black Series is praised for its distinct green sunburst dial and bezel, classic diver's dial layout, and excellent legibility with Seiko's strong lume. Owners note that the price is often discounted from the RRP, making it an excellent first proper watch. A reviewer notes a lost opportunity for a thinner appearance due to the bezel's design.
