CAL. 52850

The Portugieser Annual Calendar has a steel case with a blue dial. In three separate semicircle windows located on the dial at "12 o'clock", the annual calendar indicates the month, date and day of the week. The date change mechanism automatically takes into account the different duration of the individual months and must be corrected by hand only once a year, at the end of February. The adjustment is done by the crown. The unusual combination of the annual calendar and the seven-day manufacture reserve caliber makes this complication of the IWC manufacture even more interesting for watch connoisseurs. The sapphire crystal with accentuated camber gives the case a more slender appearance, highlighting the classic elegance of the timepiece. The arched lugs ensure greater comfort even on the thinnest wrists. The back, characterized by the transparent sapphire crystal case back, allows you to admire the splendid 52850 manufacture caliber of new conception.
