ROADMASTER M PERSIVIA

The robust bracelet appears to have a simple structure due to its linear form, but it has a tapered silhouette with slightly different sizes of the front and rear comers. The coma has a compact H-shape for the purpose of improving fit and comfort even after prolonged wear, and is satin-finished on the surface and polished on the sides and edges, a labor-intensive and costly process. It is connected to a lugless case with a similarly chic and elegant finish. And from the case to the bracelet, the watch also features 904L stainless steel, a material used by only a few of the industry's top brands.

More notably, the watch is equipped with the BALL caliber RRM7309-C, manufactured in-house by Ball Watch, which boasts up to 80 hours of runtime. This manufacture movement has passed the Swiss C.O.S.C. chronometer test (within -4 to +6 seconds per day), which guarantees the accuracy of Swiss watches, and has also passed the BALL Official Standard (within -2 to +4 seconds per day), which Ball Watch has established on its own. The movement is selected only from those that have passed the BALL Official Standard, a more rigorous precision inspection conducted by Ball Watch (day difference of -2 to +4 seconds), and is one of the most accurate in the collection. The high-precision movement can be viewed through the caseback, which is made of scratch-resistant sapphire glass, just like the windshield. The watch is a brilliant and artistic product that allows the wearer to appreciate the exquisite and artistic mechanism, from the balance beating at a steady rhythm to the beautiful traditional Swiss decorations such as the spiral perlage on the plate and the striped Côtes de Genève.
