This watch transfers with a Watch64 Sales Contract — legally binding proof of ownership under Swiss law, valid at international borders.

Payment held in escrow until watch is received and verified by buyer.


The IWC Portugieser Chronograph is a paragon of restrained elegance. This reference IW371605 in blue dial was consigned by a Zürich professional who acquired it as an investment piece. Worn fewer than ten times, it presents in near-new condition.
