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.

Tissot Supersport NBA Special Edition

The Tissot Supersport NBA Special Edition features a 45.5mm case and 100m water resistance. Owners note the bracelet tapers from 22mm to 20mm, which feels better on the wrist. Some in the community find the 44-45mm case size too large. Tissot watches are generally considered good value for the price. Overall, owners appreciate the bracelet taper for improved wearability, though some find the case size on the larger side for a quartz sports watch.
