Harry Winston might be better known as the king of diamonds, but the American luxury brand also has a long heritage in complicated watchmaking. This year marks the 20th anniversary of its iconic Ocean collection which highlights complicated mechanical watches for female connoisseurs.

The new additions to the collection this year include four women’s pieces and one piece for men. The timepieces feature complications such as retrograde hours and minutes as well as moonphase and perpetual calendar functions.

The women’s watches feature a feminine design which reflects the house’s outstanding savoir-faire and expertise in working with precious stones. The limited-edition Ocean 20th Anniversary Biretrograde Automatic 36mm, for example, features Paraiba tourmalines, diamonds and mother-of-pearl.
