Again here with Petek Philippe. In 1989, the Swiss watchmaking decided to celebrate its 150th anniversary with what the company has described as the most sophisticated watch in the world. It has 18 features, is double-sided and includes features such as a star-chart, thermometer, sunrise and sunset marker, timer, moon phase indication, and complete calendar with days, months and years. Just shocking.
