A guide for this piece: about $630, based on the 10% US charge on the declared value of goods made in Japan.

The final figure is set by US Customs and depends on where the piece was made and the kind of object it is. Many antiques over a century old carry no ordinary duty; most jewellery and leather goods add a single-digit rate.

With EMS, any charge is collected by your postal service on delivery. For pieces of significant value we can often arrange duties prepaid before dispatch.

The Piece

IWC Schaffhausen was founded in Schaffhausen, Switzerland, in 1868. The Portofino is its dress line, named for the Italian harbour town.

The silver dial carries a chronograph with a day and date display, under a sapphire crystal, and the movement winds itself. The watch was overhauled and the case refinished in March 2026. It is fitted to a crocodile-pattern leather strap with a pin buckle.

The case is 42 mm (1.65 in) across and 50 mm (1.97 in) from lug to lug, and the strap fits a wrist up to 21 cm (8.3 in). The box, guarantee card, outer box and a spare buckle are included.
