IWC Schaffhausen Portugieser Perpetual Calendar

The IWC Schaffhausen Portugieser Perpetual Calendar IW503302 has a rose gold case measuring 44.2 mm across. The case stands 14.9 mm thick, with lugs spaced 22 mm apart. An IWC-manufactured self-winding movement, calibre 52611, drives the watch and delivers a power reserve of 168 hours. The dial sits under an arched-edge sapphire crystal with antireflective coating on both sides. Complications include a perpetual calendar with date, month, weekday and year displays, along with a moon phase and a power reserve indicator. Small seconds also feature on the silver dial. The case carries a 30 metre water resistance rating. A display back reveals the movement, and the watch is fitted to a dark brown alligator leather strap by Santoni.
