What people say

Owners + reviewers, side by side

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

Casio GBM-2100A

The premium stainless steel bezel and Bluetooth connectivity are highlighted strengths. The increased mass from the metal bezel is noted as a potential drawback for some wearers. Reviewers differ on its value proposition compared to other G-Shock models.

Maen Manhattan 40

Owners appreciate the Maen Manhattan 40's thin case and unique dial, with some finding its proportions too large for smaller wrists. One owner noted a snagging crown and difficult winding action. Accuracy figures vary, with one owner reporting +18s/d to +24s/d on the 37mm version, while another owner of the 40mm model did not specify accuracy. On balance, owners and reviewers find the Maen Manhattan 40 to be a good value, with its thinness and dial finishing being key strengths.
