Rose Gold Smart Ring Size 8

The Chendssfkd R18 is a stainless steel smart ring finished in rose gold with black enamel accents. Weighing approximately 3.5 grams, it is designed for continuous all-day wear. The ring carries an IP68 waterproof rating and delivers up to 35 days of standby time on a single charge using the portable charging case or USB cable.

Health tracking for fixed size 8

This ring suits users who want continuous heart rate, blood oxygen, blood pressure, sleep stage and activity monitoring without a subscription fee. It connects via the SmartHealth app to provide daily wellness insights and weekly sleep trend analysis. Buyers who need a different finger diameter should look elsewhere, as this model is only offered in size 8 with an 18.1 mm inner diameter and 56.9 mm circumference.

18.1 mm inner diameter fixed fit

The decisive specification is the non-adjustable size 8 fitting, which measures 18.1 mm inner diameter and 56.9 mm circumference. If your finger does not match this exact dimension, the ring will not wear securely or read sensors accurately. Verify your size with a measuring kit before purchase.

Vragen over dit artikel

How much heat or power draw does the 3.5 g ring produce during continuous 24-hour wear?

The ring weighs 3.5 g and runs for 35 days on a single charge, indicating very low power consumption and negligible heat during all-day use.

Which smartphone platform and app are required to pair with the ring's Bluetooth connectivity?

You need a phone that can install the "SmartHealth" app; the ring pairs through that app rather than the system Bluetooth menu.

Will the stainless-steel band and IP68 rating survive daily contact with an older mechanical watch or metal jewellery?

The epoxy-resin and stainless-steel construction resists scratches, and the IP68 rating protects against water during normal wear alongside other accessories.
