In 2005 Patek Philippe introduced the reference 5146, which replaced the 5035 Automatic Annual Calendar. Produced from 1996 through 2005, the 5035 was the first wristwatch to contain a patented annual calendar movement. An annual calendar requires a date correction only once a year, at the end of February. Interestingly, Patek Philippe’s annual calendar movement contains more parts (330 in the 5035 and 355 in the 5146) than their current perpetual calendars and moon phases (around 275 parts), because the engineers invented a new design for this movement that allowed for the calendar displays to be quickly adjusted through correctors in the case sides.
The most notable differences between the two models were the addition of a moon phase display on the 5146, replacing the 24-hour indication display. A power reserve indicator was also added to the 5146, useful for an annual calendar so the wearer would be able to keep the watch running and not have to change the day or date. The case size of the 5146 was also increased slightly, up from 37mm to 39mm, giving the dial more space for the new functions and making the dial more readable.
The reference 5146 is a contemporary men’s dress watch, designed to be easy to use for daily wear. At the time the model was launched, Patek Philippe sought to create a watch that would have useful complications that were relevant for the 21st Century client. Combining technical innovation with elegant design, the model was first available in white gold and yellow gold, either with gray or cream dial. It later became available in rose gold with a cream dial, and platinum with a gray dial – like the current example.
With its heavy platinum case and dark gray dial, the present 5146 is the elegant and refined, perfect for every day wear.
