This guide breaks down everything you need to know about smartwatch hardware, features, brand differences, and maintenance.
Anatomy of a Smartwatch

Glass & Bezel: Toughened Gorilla Glass or scratch resistant Sapphire Crystal, encased in lightweight polymer, aluminium, or durable titanium bezels.
Optical Health Sensors: Located on the back casing to continuously track heart rate, blood oxygen (SpO2), and stress levels.
GPS & Navigation Hardware: Internal GNSS chipsets connect to GPS, GLONASS, or GALILEO satellite networks for accurate outdoor location tracking.
Motion & Environment Sensors: Built in barometric altimeters and accelerometers measure elevation changes, stair counts, and movement dynamics.
Battery & Charging Terminal: Rechargeable Lithium-ion battery, powered via magnetic pucks, wireless charging plates, or rear pin connectors.
Seals & Water Resistance: Rubber gaskets and sealed physical buttons prevent water ingress during swimming, showers, and heavy rainfall.
