Originally introduced in 1958, Model 23 was the first watch movement designed specifically for women's watches. The brand carried forward the iconic highly-curved, round two-tone stainless steel case and unique bracelet connection. The moon phase sub-dial indicates the current phase of the moon, reflecting what you see in the sky. This watch is completed with a mother-of-pearl dial and its stainless steel bracelet. The case width of this watch is 38 mm and the case height is 10.5 mm.
