OnePlus has introduced a new 43 mm version of the Watch 3, which is essentially a rebrand of the Oppo Watch X2 mini, offering a smaller and more affordable alternative to the 46 mm model.

The 43 mm Watch 3 features a 1.32-inch display, a lighter and slimmer design weighing just 37.8 grams, making it more comfortable for smaller wrists while sharing the same Snapdragon W5 Gen 1 SoC and 32 GB storage as the larger version.

This smaller model is significantly more compact and lighter, enhancing comfort and suitability for users with smaller wrists.

It includes over 100 sports modes, automatic recognition of six activity types, and health tracking features, though it lacks a temperature sensor and does not support 60-second health check-ins.

Most features of the larger model are retained, including Wear OS 5, Snapdragon W5 Gen 1 chip, 2GB RAM, 32GB storage, NFC, multiple workout modes, sleep tracking, heart rate notifications, and health apps.

Battery life on the 43 mm version is approximately two days, which is shorter than the 4-5 days of the larger model, due to size-related compromises.

With power saver mode, the 43 mm model can last up to 7 days, but this is still significantly less than the 16 days offered by the 46 mm version.

The smaller version omits some health features found in the larger model, such as a temperature sensor, Vascular Health app, and the 60s Health Check-In app.

Despite these limitations, the reviewer finds the 43mm model to be highly enjoyable and practical, especially for users who prioritize comfort and a smaller size.

Priced at $300, the 43mm model offers good value, although the larger 46mm version provides more features and longer battery life.

Overall, the 43mm version is recommended for users seeking nearly the same experience in a smaller, more manageable form factor.
