Harry Winston is one of the leading jewelers in the United States, boasting a history of about 80 years. When it entered the watch field in 1989, it quickly released timepieces that were called "masterpieces" by combining the stone setting techniques it had cultivated in jewelry with avant-garde design. Collections that combine complex movements with the brilliance of jewelry, such as Opus, HW Ocean, Project Z with a Zalium case, and the elegant Midnight and Avenue, have a unique presence. There are also a variety of avant-garde mechanisms such as micro-pavé diamonds, bezel decorations that make use of emerald cuts, retrogrades, and tourbillons. Annual production is low, making them highly valuable. The jeweler's unique aesthetic sense and challenging spirit for technological innovation are raising expectations for the next work.
