Suuntoさんのインスタグラム写真 - (SuuntoInstagram)「Did you know that the titanium version of Suunto Vertical has a solar charging feature charging your watch when it is exposed to light? Special solar widget shows both a complication icon showing how much solar energy is currently being harvested as well as summary of how much solar energy was harvested during the last 3 hrs. Each bar stands for past 10 minutes average. For a full bar you need approximately 50000lux of sun light. On a sunny day, the sun can provide your watch with 30% longer battery life! #Suunto #SuuntoVertical #AdventureStartsHere」9月12日 20時00分
