Shop Owner’s Thoughts: While the U1 is often considered the quintessential Zenith diver’s watch, this U50—measuring 41 mm in diameter and 11.15 mm thick—is a bit smaller than the U1’s 44 mm diameter and 14.7 mm thickness, making it a diver’s watch well-suited for Japanese wearers.Furthermore, while the classic black dial is standard for divers’ watches, this U50.S.Perlmutt.S features—as the name suggests—a white mother-of-pearl dial. Even among rugged divers’ watches, it exudes elegance, making it a fashion-forward timepiece perfectly suited for everyday city wear. Given that the U1 is the top-selling model in Germany, this U50 series—limited to just 500 pieces worldwide—is likely to sell out in no time!
