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 noted for its robust, edgy design with industrial fonts and scratch-resistant Duratect MRK and DLC coatings. Reviewers highlight its intuitive and satisfying bezel locking mechanism and the substantial 4mm anti-reflective sapphire crystal. This dive watch utilizes an Eco-Drive E365 quartz movement, offering a 365-day power reserve and an end-of-life indicator, and is recognized as the first ISO 6425 compliant watch with a solar-powered movement. However, its massive 52.5mm diameter and 22mm thickness make it unsuitable for everyday wear. On balance, the Citizen Promaster Professional Diver is recognized for its specialized, robust build and innovative solar-powered movement, though its size limits its wearability.
