IWC is reissuing the Portugieser Chronograph Classic (Ref. 3903) with a slightly revised and updated design. In 2013, it had launched the Reference 3904 – the third Chronograph in the Portugieser family which retains the unmistakable character of the originals from the 1930s.
The dial with the typical Portugieser railway-trackstyle chapter ring looks neater than its predecessor without the subdivision of the seconds, while the watch as a whole has a more modern impact thanks to the convex sapphire glass.
The top-of-the-line version has an 18-ct red gold case and a silver-plated dial, as well as golden hands and appliqués. It is fitted with a hand-finished brown alligator leather strap. Two models are available with a stainless-steel case and a black alligator leather strap. One features a silver-plated dial and blue hands and appliqués, while the other has a midnight blue dial and rhodium-plated hands and appliqués.
The new Chronographs are driven by the tried-and-tested IWC-manufactured 89361 calibre with flyback function, self-winding system and a power reserve of 68 hours. The recorded time is particularly easy to read on the combined hour and minute counter at “12 o’clock”. A see-through sapphire-glass back provides a view of the movement and the rotor, which is adorned with Geneva stripes.
