The patented annual calendar featuring day, date, and month displays is one of the most sought-after models from the Swiss manufacturer. Its intelligent mechanism, the self-winding caliber 324 S QA LU, requires manual adjustment only once a year, specifically when transitioning from February to March. The reference 4947/1A showcases this sophisticated complication for the first time in a round Calatrava-style stainless steel case. With a diameter of 38 millimeters and mounted on an integrated stainless steel bracelet, this watch offers exceptional comfort, even on slimmer wrists. The midnight blue dial, accentuated by both vertical and horizontal satin finishes, beautifully complements the shiny steel, resulting in a perfectly elegant timepiece.
