Portugieser Perpetual Calendar

Reference IW503312 was added to the collection in 2020. This watch has an 'Armor' red gold case and a blue dial. Celebrating the 75th Anniversary of the Portugieser (or Portuguese) in 2015, IWC revamped nearly the full collection - introducing models, new complications and updating a good part of the existing collection. The 2015 Portugieser Perpetual Calendar still looks familiar, although it was revamped quite drastically compared to the pre-2015 model. The arched glass is one of the most notable changes, although both the case as well as the dial also got a subtle redesign. The automatic movement with a 7-day power reserve and pellaton winding system now sports twin barrels.
