"Sapphire pulse" is an elegant and futuristic watchface that pulsates with a beautiful glowing animation. Hidden in the background are the hour index marks, as well as discrete battery level indicator - both visible only when the pulse reaches the outer edges of the screen.
The overall approach to design was deliberate, tasteful and restrained - we wanted to make a watchface that will be sleek, modern, attractive and cool - without going "too far" with effects. The numbers certainly speak for themselves, as this is among the most popular watchfaces we ever released.
As for the functionality, apart from the battery level indicator, at the bottom of the face is a hidden Step counter. Also, when the battery drops below 10 percent, the pulsing animation changes to red to warn the user it's time for a recharge.
The watchface is extremely optimized and will have a minimal effect on the battery life. Included are the always-on modes for both the Gear S2 and S3. The video is showing the Emerald version - this watchface is exactly the same, only in Sapphire blue color.
