IWC is not resting on its laurels, as evidenced by its recently announced Laureus and Goodwood limited editions. The latest new releases, announced just this week, are two new models in its elegant Portofino line, both representing firsts for the IWC Replica Watches For Men Schaffhausen-based brand. What makes these new versions of the Portofino Hand-Wound Eight Days notable?

The first of the new additions to the IWC Portofino Replica Watches collection, introduced in 1984 and most recently revamped in 2011, features a slate gray dial and a 45-mm stainless steel case mounted on a beige-colored suede strap, the latter used for the first time in an IWC timepiece. The strap’s “soft, roughened surface,” IWC says, not only provides an attractive companion to the dial but also a high degree of comfort on the wrist. The dial features the now-familiar layout established by this model’s predecessors, with applied indices and Roman numeral, date window at 3 o’clock, small seconds at 6 o’clock, and a power-reserve indicator at 9 o’clock.

The other newcomer, with the same dial layout, case materials, and dimensions, offers a new combination of color and materials for IWC, with a deep blue sunburst dial matched with a steel Milanese bracelet. Both watches are powered by IWC Replica manufacture Caliber 59210, a hand-wound movement that promises 192 hours, or eight days, of reliable, accurate running time when fully wound.

The exceptional movement inside the watches, whose indexless balance uses a Breguet spring and beats at a frequency of 28,800 vph, is distinguished by its ability to stop after eight days, the period for which it is designed to have a constant driving torque, even though the movement itself could run at a slightly diminished accuracy for a ninth day. And thanks to the Swiss IWC Replica Watches prominent power-reserve display on the dial, the wearer will always know when it is time to rewind the watch. On display through the expansive sapphire caseback, Caliber 59210 features an eye-catching c?tes de Genève finish on its large mainplate.
