I received it two weeks ago for my name day, and I’m absolutely thrilled with the gift. It combines durability with an interesting design—the plastic construction, enhanced with Carbon Core Guard, feels sturdy, while the metallic accents give it a modern look. The battery is rated for 10 years—which is impressive—and I really don’t have to worry about replacing it, while features like the stopwatch, analog time display, and LED backlight are very practical. Water resistance up to 200 m gives me freedom around water, but the large dial and certain reflections on the crystal sometimes make it difficult to quickly read the time in bright light.
