    This yellow G-SHOCK is a real showstopper for anyone who wants to stand out from the crowd. The Tone on Tone version from the Octagon collection looks incredibly fresh and energetic, and this intense color makes the watch the focal point of any casual outfit. Despite its lightness and slim case—a rarity in this product family—it still features Carbon Core Guard technology, so durability is a given. I really like that the dial is easy to read, and the Neobrite coating on the hands lets you quickly check the time, even in total darkness. The water resistance rating of up to 200 meters gives me a sense of security while swimming or on vacation adventures, and the shock-resistant construction makes this a virtually indestructible piece of gear. The world time function and automatic calendar, in turn, are great conveniences for frequent travelers. It’s simply the perfect blend of iconic design and a modern, bold color that lifts my spirits every time I put it on my wrist.
