What people say

Owners + reviewers, side by side

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

Astor + Banks Chrono

Owners widely praise the Astor + Banks Chrono for its sporty design, wrist-friendly 38.5mm size, and enthusiast-friendly price starting at $525. One reviewer notes the date numeral is consistently half in shadow due to deep-set placement. On balance, owners and reviewers rate the Astor + Banks Chrono highly for its design and value at the price point.

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.
