The ceramic body is smooth, light, and scratch-resistant, making it comfortable for 24/7 wear. Available in matte black from size 7 to 14, you can choose between a line charger or a compact charging case.

Features and Construction

The smart ring combines advanced sensor technology with everyday usability. Its ceramic finish provides durability without adding weight, while the built-in 20mAh battery keeps the device running through the day.

Material and Build

The ring is made of ceramic, a material known for its hardness and scratch resistance, which helps maintain a clean appearance over time. The smooth surface is comfortable against the skin and easy to slide on and off. Inside, the ring houses optical sensors for heart rate and blood oxygen monitoring, plus an accelerometer for sleep tracking.

Size and Practical Fit

Covering sizes 7 to 14 in standard US ring sizing, the ring fits a wide range of finger sizes. It is slim and lightweight enough to wear alongside other jewellery or on its own. The black colour is neutral and unobtrusive, suitable for both casual and professional settings.

Uses and Placement

This ring is designed for continuous health tracking throughout the day and night. Its waterproof nature adds flexibility for active lifestyles.

Event or Professional Use

Wear it to the gym, on a run, or while swimming for real-time heart rate and SpO2 data. The ceramic body withstands sweat, rain, and accidental splashes, so you don't need to remove it during most activities. Sleep tracking uses the accelerometer to detect movement and sleep cycles, providing morning reports on rest quality.

Everyday Home Use

At home, the ring continues to monitor your health passively – whether you're working, relaxing, or sleeping. The display-free design means no screen glare or distraction, just silent data collection linked to your phone. It is comfortable enough for overnight wear, so you can track sleep without noticing.

Benefits and Buying Value

The ring offers practical health insights without the need for a bulky device. Its ceramic build ensures it stays looking new, and the waterproofing extends its usable scenarios.

Reuse and Low Maintenance

The 20mAh battery recharges via the included line charger or charging case – no wires to manage with the case option. Daily charging is recommended for continuous use. The ceramic surface wipes clean easily with a soft cloth. No screen protectors or special care needed for the sensor lenses.

Why Choose This Product

If you want health tracking that is subtle, waterproof, and comfortable for 24/7 wear, this ceramic smart ring delivers. It covers the core metrics – heart rate, blood oxygen, and sleep – without unnecessary complexity. The choice of charger style and multiple sizes makes it easy to find a fit that works for you.
