The color tuning fits feminine aesthetic styles. Preloaded dials adopt soft warm tones to match daily women’s dressing styles.

Lightweight Metal Housing & Slim Body Structure

Meanwhile, polished lightweight metal forms the whole watch frame. The ultra-slim 10.1 mm thickness avoids heavy pressure on female wrists during all-day wear.

No extra bulky physical keys occupy the side casing. The minimalist outline maintains a smooth delicate look for daily fashion matching.

Light Net Weight & Dual Replaceable Strap Series

More importantly, the finished watch weighs only 28 g without straps. It will not cause wrist soreness after long-time daily wear.

Two complete strap styles support multi-scene matching. One set is fine Milanese metal bands for formal outfits. The other set is soft sweat-proof silicone straps with rose gold, pink, gray and black color options.

As a result, Milanese metal straps do not contain internal waterproof sealing layers. Users must switch back to original silicone straps before any handwashing or rain exposure. This action protects internal circuit and sensor parts from permanent water damage.

2.2 Bluetooth 5.4 Connection & Two-Way Call Hardware Layout

Low-Power Bluetooth Chip & Mobile System Compatibility

Furthermore, a low-power Bluetooth 5.4 chip keeps stable long-distance pairing with smartphones. It saves offline call logs, health records and sport data inside local watch memory.
