Patek Philippe is dedicated to the development of exciting watch complications for women, and 2014 saw the launch of two new feminine Moon phase watches from the Swiss watchmaker. The Patek Philippe Calatrava Moon phase watch, reference 7121/1J-001, has a classic 33mm Calatrava case in yellow gold, illuminated by a bezel set with 66 brilliant-cut diamonds. The creamy white dial has appliqué Arabic numerals and Breguet-style hour and minute hands. The Moon phase indicator, which doubles up as a small seconds counter, is located at 6 o'clock, with the Moon and stars dusted in gold. Presented on a sumptuous yellow gold link bracelet, fastened with a fold-over clasp, the movement is a classic Patek Philippe calibre 215 PS LU, visible through the sapphire case back, providing a 44-hour power reserve and water resistance up to 30m.
