Thermals noise and power draw

The 25g body produces no noticeable heat during continuous monitoring. Passive cooling keeps the device silent in any environment. A lithium polymer cell powers 24/7 tracking without daily charging interruptions. Low energy demand suits extended active use.

Questions about this item

How do I pair the RTGY smart watch with the QRing app on my phone?

Enable Bluetooth on your iOS or Android device, open the free QRing app, and follow the on-screen pairing steps; the watch syncs automatically once connected.

Which parts of the RTGY watch will need replacement over time?

The two included nylon straps in different lengths can be swapped when worn, and the lithium-polymer battery will eventually require recharging more often as it ages.

How long does the 25g RTGY watch run before the battery needs recharging during continuous health tracking?

With 24/7 heart-rate, HRV and stress monitoring active, the battery typically lasts several days before a recharge is needed.
