Commentary:
In the short production period of 13 years from 1941 to 1954, the chronograph perpetual calendar 1518 produced 285 pieces in four generations, most of which were precious metal models (gold and rose gold), a total of 281, and stainless steel models are currently known Only 4 of them. This watch is the first 1518, featuring gold Arabic numerals. The second generation was introduced during Basel in 1942, with 12 o’clock gold time scales, the others being enamel layered time scales. The third generation eliminated the enamel layer on the time scales, while the fourth generation began to use gold baton time scales.
