Ref. 3445, frequently referred to as the 'Monodate', was the first calendar wristwatch produced by the company in series. It is one of the most popular automatic wristwatches made by Patek Philippe and incorporates the legendary calibre 27-460. This calibre is known for its efficiency and exceptional quality. To ensure that the watch is continually and smoothly wound when worn, a gold rotor is incorporated. The reason gold is chosen for the rotor is due to its gravity which is almost twice that of lead.
