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.

Nezumi Studios Corbeau

The Nezumi Studios Corbeau is widely praised for its retro, mil-spec-inspired design, featuring a playful and vibrant color palette with a creamy dial, mustard numerals, and pumpkin lume. Owners and reviewers highlight its comfortable 40mm wearability, with stubby lugs making it wear smaller than expected, and appreciate the reliable Seiko VK63 meca-quartz movement. The chronograph operation is noted for its firm, reassuring clicks and the bezel turns with crisp action, contributing to a solid, well-made feel for its price point. One owner notes the 50m water resistance as a limitation. On balance, owners and reviewers rate the Nezumi Studios Corbeau highly for its distinctive vintage aesthetic and excellent value.

From video reviewers

The Nezumi Corbeau V2 features an improved dial and handset. Reviewers noted a desire for brighter lume and increased water resistance.
