For serious athletes and outdoor enthusiasts, the search for a professional-grade sports watch often ends in sticker shock. High-end GPS wearables that offer accurate tracking, long-lasting battery modes, and genuine water resistance typically cost hundreds of dollars. Many enthusiasts settle for basic fitness trackers that lack specialized sports data, or worse, they buy budget watches that fail the moment they hit the water or lose GPS signal under tree cover.

The Amazfit Stratos 3 is the ultimate “pro-sumer” solution, now available at an incredible value as a demonstration unit with its original box. Designed for professional sports, it features a dual-core system that allows you to switch between smart mode and an ultra-endurance mode. With its 5ATM waterproof rating and integrated Sony GPS chip, it provides the precision and durability required for triathlons, trail running, and open-water swimming without the flagship price tag.
