Round Screen Smartwatch GTR3 Sports Watch 3ATM Waterproof Heart Rate Monitoring Bracelet Flagship High

AMO Round Screen Smartwatch GTR3 - Equipped with 1.43-inch AMOLED fluid screen, it adopts diamond-like pixel arrangement to realize 326PPI super retina display, and 1000nit peak brightness together with infinite color temperature adjustment technology, which allows you to read the information clearly even under strong light. The watch body adopts aerospace-grade zinc alloy center frame and nano-scale vacuum ion coating technology to form a 5-layer fingerprint-resistant composite structure, together with quick-release magnetic strap system (silicone/leather/stainless steel tri-form), realizing free switching between business, sports and fashion scenarios.

The core is equipped with a four-channel BioTrack Pro biosensor, which realizes medical-grade monitoring accuracy through multimodal algorithm fusion: 24-hour dynamic heart rate monitoring error ≤ 2bpm, oxygen saturation detection speed is upgraded to 15 seconds/times, and with sleep phase tracking technology it can recognize REM rapid eye movement cycle. The unique “Motion Brain 3.0” system integrates 100+ professional modes, relying on nine-axis motion sensors and self-developed ExerMotion algorithms, which can intelligently recognize 8 types of regular sports such as running, swimming, cycling and generate 3D trajectory maps.

The hardware level breakthrough realizes dual-mode Bluetooth 5.3 architecture, supports HD call noise reduction and offline voice assistant linkage, and in case of emergency, SOS satellite positioning alarm can be triggered by long-pressing the crown. The optional version is equipped with NFC 3.0 chipset, which supports dual ecosystems of digital car key and Alipay offline payment. 450mAh silicon carbon anode battery with dynamic power management realizes 10 days of long-lasting battery life under the mode of all-day health monitoring and 1 hour exercise per day, and the magnetic fast-charging technology realizes charging to 80% in 45 minutes.

The product has passed the 3ATM military grade waterproof certification, built-in underwater heart rate algorithm and swimming trip counter, which is deeply suitable for water sports scenarios. From the zinc alloy body's micro-arc oxidation coloring process to the customizable mechanical skeleton dial, RUNMEFIT redefines the aesthetic benchmark of smart wear with the concept of “Art of Wearing Technology”.
