Portugieser Jubilee

The IWC Portugieser Jubilee celebrates the 125th anniversary of IWC and pays tribute to the original Portugieser from the late 1930s, a watch commissioned by two Portuguese businessmen seeking marine-chronometer precision in a wristwatch. This limited edition stands out for its clean, enamel-like dial, classic feuille hands, and a case size—42.3mm—that echoes the bold proportions of the original. Collectors value this model not just for its heritage but for its faithful aesthetic and commemorative significance within the Portugieser lineup.

Reference IW5441 is the most sought-after variant, produced in 1993 in three metals: stainless steel (1,000 pieces), yellow gold (500 pieces), and platinum (250 pieces). The stainless steel version commands a premium due to its rarity and the desirability of steel in the IWC collector community. Key price drivers include condition, completeness (box and papers are a plus), and dial aging—original, unblemished dials are especially prized, as the lacquer can develop hairlines over time.

Inside beats the hand-wound Caliber 9828, derived from IWC’s legendary pocket watch movements, visible through a sapphire caseback. This movement’s finishing, swan-neck regulator, and slow-beat frequency are all talking points for collectors who appreciate traditional watchmaking. Water resistance is minimal, so this is a dress watch through and through. When shopping, ensure the movement number matches the period-correct range; service history can also affect value, as unpolished cases and original parts matter to purists.
