Why it makes a good gift
Best for : A man who wants a rugged sport watch that stays accurate without battery changes, for travel or daily wear.
Best occasion : A birthday, Father's Day or Christmas.
Why it works : A watch he can wear every day and rarely maintain: solar charging and radio-synchronized time keep it accurate, and the metal band looks dressier than a resin G-Shock. About 3,700 reviews at 4.6 stars, at about $127.
Avoid if : He prefers a slim dress watch: the case is a chunky G-Shock. The listing's atomic sync list mentions Chinese transmitters among six signals, so check coverage for where he lives.
