Resco DLC WhitevsSeiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition

Owners report satisfaction with the DLC coating, with one stating it is considered indestructible and the gold standard. Another owner chose the Resco DLC White specifically for this coating, expecting it to resist scratches better than previous coatings. One owner noted rust on the case by the time and date adjusting screw of a different Resco model, which the company stated was normal. Overall, owners value the durability and scratch resistance of the DLC coating on the Resco DLC White.

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition for its attractive dial with a jewel-toned teal color and rippling-water pattern, and its smooth bezel action. Some owners find it a refined evolution of previous models with a comfortable case and bracelet. However, a significant number of owners express disappointment with the accuracy of the 6R movement at its price point, with some noting it runs slow. The steep rehaut and marker size make the 24-hour numbers difficult to read, and the case design is described as making the watch feel top-heavy. On balance, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition highly for its striking dial and refined design, despite widespread concerns about the movement's accuracy for the price.
