What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Baltic Aquascaphe Dual-Crown

The Baltic Aquascaphe Dual-Crown is widely praised for its modern take on a vintage Super Compressor design, featuring a legible internal bezel and a clean, balanced dial. Reviewers consistently highlight its excellent wearability, attributed to its 39mm case size with elegant proportions and slender flanks. The case finishing, including polished chamfers and a unique brushed bezel top, is also a noted strength. It is powered by the Miyota 9039 movement, offering 200m water resistance. One reviewer found operating the internal bezel crown to be a fiddly and slower experience compared to standard dive bezels, and another noted the domed sapphire crystal can be somewhat reflective. Prices ranged from €550 during pre-order to €780 retail. Overall, reviewers rate the Baltic Aquascaphe Dual-Crown highly for its charming vintage-inspired design and excellent value.

From video reviewers

The watch's bezel action is smooth and precise, making it easy to turn. A weakness of the watch is its lume, which is somewhat lacking in low-light conditions. Reviewers disagree on the lug-to-lug fit, with one reviewer calling it comfortable for everyday wear and the other describing it as relatively slim for smaller wrists.

Citizen Promaster Professional Diver

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.
