How to Use It
Get started with the Masimo W1 Advanced Health Tracking Watch
Download the Masimo Health app, then follow the instructions in the app to pair your Masimo W1.
Put on Your Watch
Place the watch on the flat part of your wrist, avoiding the wrist bone. Tighten the M-band™ so the watch does not slide on the wrist. Then tighten one or two more notches. To obtain good health data, the watch needs to be snug (but not uncomfortably tight).
Start a Health Measurement
Press the top button on the right side of the watch to access the main menu. Touch the SpO2 icon and press start to initiate a measurement.
Pair Your Watch
In the Masimo Health App, choose Device from the Menu. Press the Add Device button, then select Masimo W1 from the list of devices and follow the instructions for pairing the watch to your mobile device.
