Its 1.57″ LCD touchscreen delivers a 240 x 240 px resolution at 235 ppi, and the watch does not feature an Always-On Display, branded damage-resistant glass, or sapphire glass. The device carries an IP67 rating and 5 ATM water resistance, offering solid protection against water exposure, and the 18 mm band is replaceable for customization. It is not designed for children.

The Moto Watch 40 includes a heart rate monitor and pulse oximeter for tracking cardiovascular activity and blood oxygen levels, along with an accelerometer for motion detection. It does not feature GPS, a gyroscope, barometer, compass, body temperature sensor, cadence sensor, or perspiration monitor, keeping the sensor set focused on core health metrics.

The Moto Watch 40 covers the essentials of daily activity tracking, monitoring steps, sleep, and calorie intake, and providing detailed sleep reports alongside automatic activity detection.

The Moto Watch 40 is powered by a 240 mAh rechargeable battery rated for up to 10 days of battery life. The battery is non-removable and does not support wireless or solar charging, so it relies solely on wired charging to replenish.
