Model "トノーカーベックス" on behalf of Frank Muller developed with brand birth of 1992. Because the case design that the three-dimensional curve that put トノー (barrel) and car Beck's (curve) together is beautiful curves to the camera back along an arm, it is superior in a fitting feeling. The big, unique Arabic numeric is called “ Byzantine numerals “ (number of the Byzantinism), popular name "ビザン number", and it is one of Frank Muller and the designs to know at first sight. The inter-midi bait is that is one size smaller than general lady's size. The pretty small-sized case size matches a Japanese arm well.
