button controls
Product 1: Samsung Galaxy Watch 8

Contactless payments are supported through NFC/Zepp Pay/Curve in supported regions, but availability is country- and bank-dependent.

cross-platform compatibility
Product 1: Samsung Galaxy Watch 8

Product 1: Samsung Galaxy Watch 8
4.0

LTE is available as an option and can support standalone use, but several mentions frame it as an add-on rather than a core tested strength.

Product 2: Amazfit Active 3 Premium

4.5
