Problems It Solves
- Wrist wearables are taken off at night, which is when sleep data mattersA 3.8 g ring is comfortable enough to keep on, so sleep and overnight heart rate are actually captured.
- Charging is the point where wearables get abandonedMagnetic charging with an optional charging case removes the port and the proprietary cradle.
- Skin reaction and finish wear kill repeat purchaseAntibacterial austenitic stainless steel and zirconium nano-ceramic surfaces resist scratching and wear.
- An access card is one more thing to carryThe NFC model handles smart access control alongside the health sensors, at 7 mm thickness.
Materials And Manufacturing
Shell materials are published per model: microcrystalline zirconium nano-ceramic, austenitic antibacterial stainless steel, antibacterial stainless steel with a transparent oxidised resin inner shell, enamel filled with oil paints, or a ceramic surface on the NFC model. Every model is rated IP68.

Use Guide
How to specify and evaluate this model before you commit to an order.
Specifying It
- Choose the shell material first — ceramic, enamel and stainless steel are different tooling routes.
- Confirm which sensors the market claim requires; heart rate, blood oxygen and blood pressure are separate stacks.
- Decide whether NFC access control is in scope before size tooling starts.
- Agree the ring size range and sizing kit for your market at sample stage.
Evaluating The Sample
- Check the published figures against the sample rather than against the datasheet
- Test at the volume and distance your customer will actually use
- Confirm the finish and print in the light of your retail environment
- Run the packaging drop before you approve the carton
- Agree the retained approval sample as the production reference
