The IWC Portugieser Regulateur Wempe Edition, reference IW544301, is an uncommon take on the Portugieser, pairing the collection's marine chronometer-inspired design with a regulator display drawn from traditional precision clocks. Produced around 2005 as a limited edition of 100 pieces for Wempe, it carries an added layer of retailer-specific appeal that sets it apart from the standard Portugieser Regulateur references. The 43mm stainless steel case houses a silver dial with classic Portugieser Arabic numerals and feuille hands. Its regulator layout gives the minutes center position, with separate hour and seconds displays, a format prized for its legibility and its connection to traditional timekeeping instruments. Power comes from the hand-wound IWC caliber 98245, a movement rooted in the brand's large pocket watch calibers. It suits the watch well, both mechanically and stylistically, and reinforces the traditional character of the piece. Collectors continue to seek out this movement family for its architecture, slower beat rate, and close link to the oversized hand-wound Portugieser models that shaped modern IWC. What distinguishes the Wempe edition is not just its limited production, but the regulator display itself, a format that tends to resonate most with experienced collectors. Fitted on an alligator strap, the watch keeps the long, elegant profile that defines the Portugieser line. For buyers looking beyond the familiar chronograph and power reserve models, the IW544301 offers something more specific: a restrained, mechanically traditional Portugieser with real collector interest and a less common configuration.
