Verdict

The Lenovo E1 is a budget-friendly smartwatch featuring a 1.33-inch LCD color display with 240x230 resolution, protected by 2.5D toughened glass with 7H hardness to resist scratches. It offers a 180mAh lithium polymer battery providing up to 10 days of active use and 25 days of standby, alongside essential health tracking such as 24-hour heart rate and sleep monitoring. Built for sports enthusiasts, it includes seven dedicated exercise modes—including running, cycling, and skipping—within a lightweight 58g zinc-alloy rectangular case that holds an IP67 water-resistance rating. Major pros include its durable build quality, long-lasting battery life for its price bracket, and highly customizable watch faces via the app. However, users have noted several cons, such as its single-touch navigation button rather than a full touchscreen, the lack of built-in GPS, and a companion app that some find unintuitive or prone to syncing issues.
