What people say

Owners + reviewers, side by side

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

Citizen Promaster Skyhawk A-T

The Citizen Promaster Skyhawk A-T is widely praised for its blend of functionality, toughness, and value, featuring an Eco-Drive movement with atomic timekeeping and a slide rule bezel. Reviewers highlight its legible dial with multiple complications and 200m water resistance. Owners note that titanium models wear better than stainless steel versions, with one user describing the latter as a "boat anchor." The watch offers significant functionality and value at its price point. Overall, owners and reviewers rate the Citizen Promaster Skyhawk A-T highly for its extensive features and robust build at an accessible price.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
