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.

Zelos Swordfish 3

Owners widely praise the Zelos Swordfish 3 for its strong value, with reviewers highlighting the textured sandwich dial, Seiko NH35 movement, 200m water resistance, and surprisingly good bracelet.
