Our take on the Portugieser Perpetual Calendar 44 IW503704

The IWC Portugieser Perpetual Calendar 44 is a large white gold dress watch built around IWC's in-house Calibre 52616. Its perpetual calendar shows date, day, month, a four-digit year and a perpetual moon phase, and it runs for seven days on one wind. The 44.4 mm case and 14.9 mm height make it a big watch for a formal piece, so it suits larger wrists and collectors who want a full calendar in white gold. Against perpetual calendars from other houses it stands out for the long power reserve and the legible, symmetrical dial layout rather than for slimness.

Questions and answers

How does the Portugieser Perpetual Calendar 44 differ from the 42 mm version?
The 44 has the larger case and the Calibre 52616 with a seven-day power reserve. The smaller version uses a different movement and a more compact case, so it suits narrower wrists.
Does the calendar need resetting often?
No. The perpetual calendar accounts for leap years and needs correction only around 2100. Keep it wound, since a stopped movement means resetting the displays with the pushers.
Is 44.4 mm too big for everyday wear?
It is a large, tall watch at 14.9 mm, so it sits prominently under a cuff. It works best on wrists of roughly 18 cm and up, or as a dress piece worn occasionally.
Can it be worn swimming?
Water resistance is 5 bar, which covers splashes and rain but not swimming or diving. The alligator strap should stay away from water.
What is in the box?
The watch on its Santoni alligator strap with a deployant buckle, plus IWC's warranty and paperwork. A setting pusher and travel case are typical, but confirm the contents with the seller.
How accurate is the Calibre 52616?
It beats at 4 Hz and is built to IWC's tolerances, but it is not a chronometer-certified movement. Expect it to run within a few seconds a day, checked over the seven-day reserve.
Where is the Portugieser Perpetual Calendar 44 IW503704 cheapest?
At Artimeus, for $51,000.00, 15% under what the other stores charge, as of our latest check.
Where can I buy the Portugieser Perpetual Calendar 44 IW503704?
8 stores we checked sell it, including CH Premier Jewelers, Burdeen's Jewelry, Greenleaf & Crosby, CJ Charles Jewelers, WATCHXNYC.
