The Tank Must small model features a high-autonomy quartz movement housed in a refined steel case with a beaded crown set with a synthetic cabochon-shaped spinel. Its silvered dial is complemented by blued-steel sword-shaped hands, while the interchangeable steel bracelet ensures both comfort and versatility. The case measures 29.5 × 22 mm with a slim 6.6 mm profile, offering an elegant fit for daily wear. The watch has passed the 30-meter water-resistance test under 3-ATM pressure, though swimming is not recommended for any watch, whether genuine or replica. As a 1:1 super clone Swiss-mechanism model, it matches the authentic piece in serial number arrangement, font and printing quality, case thickness, size, and overall finishing, delivering the same movement performance and visual accuracy—so precise that even a jeweler would not detect the difference. All Swiss-mechanism models include a full 2-year International United Luxury warranty. For Asian-mechanism versions, the materials and movements may differ; customers are welcome to contact support for detailed information or additional videos.
