Citizen Promaster Professional DivervsDryden Chrono Diver Series 1

The Citizen Promaster Professional Diver is a serious instrument with a robust technical appearance, featuring strong lines and an aggressive bezel. It utilizes Citizen's Duratect MRK and DLC coatings for scratch resistance. The BN1024-01E model offers a 300m depth rating and a sapphire crystal, with a 365-day power reserve from its Eco-Drive quartz movement. However, its large size, measuring 52.5mm in diameter and nearly 22mm thick, makes it unsuitable for everyday wear. One reviewer notes the absence of an orange minute hand, which is considered effective on other Promaster models. On balance, the Citizen Promaster Professional Diver is a highly capable, albeit massive, dive tool, with its scratch resistance and long power reserve being key strengths.

The Dryden Chrono Diver Series 1 is a 42mm mechaquartz chronograph featuring a dual-curved sapphire crystal and 100m water resistance. Owners note the VK63 movement's characteristic chronograph hand not resetting perfectly to zero, a trait present on this specific watch. The case exhibits polished chamfers on the upper lugs, and it utilizes Swiss Superluminova BGW9. On balance, owners appreciate the classic case shape and dial design of the Dryden Chrono Diver Series 1 at its price point, despite the mechaquartz movement's known reset behavior.
