COLMI R12 Smart Ring - Touchscreen Display, 5ATM Waterproof, Wireless Charging

A smart ring tracks everything a watch does while being genuinely invisible - no screen glowing on your wrist at night, nothing to catch on a sleeve. The R12 goes a step further than most by putting an actual touchscreen display on the ring itself, so you can check your data without reaching for a phone.

AT A GLANCE

• Built-in touchscreen display on the ring
• Heart rate, SpO2, sleep and stress monitoring
• 5ATM waterproof - safe for swimming and showering
• Wireless charging, 7-9 days per charge

WHY YOU'LL LOVE IT

• A Display on a Ring: Most smart rings force you into the phone app for everything. A built-in screen and touchpad means a glance is enough for the basics.
• Better Sleep Data Than a Watch: A ring is far more comfortable to wear overnight than a watch, which is exactly why the sleep and recovery tracking is more likely to be worn consistently.
• Full Health Picture: Heart rate, blood oxygen, sleep stages and stress monitoring run continuously through the day and night.
• Wear It Everywhere: 5ATM waterproofing means swimming, showering and washing up are all fine - you never need to take it off.
• Charge Once a Week: 7-9 days per charge on wireless charging, so it stays on your finger rather than sitting on a dock.
• Activity Tracking Too: Steps, distance, calories and activity levels are tracked alongside the health metrics.
