Heritage In The IWC Portofino Hand-Wound Big Date

Large date complications are in vogue with contemporary design trends, but they are far from a new feature on an IWC replica watch. The tradition of including a large, easy to read date aperture is one that dates back to 1885 for IWC Schaffhausen, and it again appears on the Portofino Hand-Wound Big Date, as introduced at the 2013 Watches & Wonders fair in Hong Kong. The inclusion of a large date aperture compliments the already impressive dial landscape, which is derived from the IWC manufactured 59230.

Equally as useful as the big date, is the incredible 8-days of power reserve that the calibre 59230 provides. The Portofino Hand-Wound Big Date will run continuously for 8-days, or 192 hours, at peak accuracy. To prevent and compromises to accuracy, the watch will stop running once the reserve is spent, ensuring you’ll never never need to stress about the current state of your wind. The hand winding element of the movement creates an intimate connection between wearer and watch, bridging the gap between practicality, and interaction.

The dial layout of the newest Portofino is clean and modern, with classical inspiration. The date aperture placed under the Roman twelve creates a symmetry with the running seconds hand at 6 o’clock on the dial. The power reserve complication is displayed discreetly, yet usefully at the 9 o’clock position. The small accents of red in the power reserve and running seconds hand display are a subtle detail to be discovered.

The IWC manufacture movement, calibre 59230, features large bridges and plates classically decorated in “Côtes de Genève”. The movement fills the entirety of the sapphire exhibition caseback, and its small recesses (along with its 30 jewels) elude to the underpinnings of an impressive spring barrel feeding a robust gear train. Of course, the balance wheel is in full view, spinning away at 28,800 bph.

Overall the IWC Big Date is a beautifully engineered timepiece that balances classical good looks with technologically advanced execution. Never do the complications feel forced or in the way, they merely accentuate the already handsome Portofino Hand-Wound line with another layer of practicality.
