Smart and lightweight GPS multisport watch: The Suunto 5 PEAK is a complement to the main Suunto 5 range. Functionally equivalent to other Suunto GPS models. Ideal for those who are looking for a quality watch with sports functions and don't want to invest more money than is necessary. The watch will delight those who appreciate its light weight as well as irs fine-tuned sports functions over the imperfect apps of conventional smartwatches. The watch is reliable, but unlike other Suunto watches, it is not repairable (however, the vast majority of GPS watch brands are not repairable). The glass is polyamide ( but you can buy a protective film). The advantage of this construction is that it is very lightweight.
