The IWC Replica Portugieser Tourbillon Rétrograde Chronograph (ref. IW3940) and Portugieser Perpetual Calendar Tourbillon (ref. IW5045).
Both timepieces use tourbillon movements and offer a retrograde chronograph and perpetual calendar, respectively. The references are available in limited quantities in rose gold and platinum, each produced with either a familiar silver or blue dial.
The Best IWC Replica has a 45-mm Portugieser case, with curved lugs and a relatively large crown. The dial’s outer edge features a railroad minute track recalling the marine chronometers that originally inspired the series, while applied Arabic numerals decorate most hour positions. Each of the dial’s four sectors hosts a different feature.
The right-hand side features an analog date indicator as well as a display for the impressive 7-day power reserve. Opposite this we find a 9 o’clock analog day indicator, with Copy IWC Watch branding at its center and a display for the year slightly below it brushing the 8 o’clock mark. Toward the bottom is an analog month indicator as well as the moon-phase, while the top is dedicated to showcasing the large aperture for the watch’s namesake tourbillon. Passing over the dial are two leaf hands for the hours and minutes.
This array of functions is powered by the Replica IWC Caliber 51950, an automatic movement with a gold oscillating rotor, visible via a sapphire caseback. Both the blue-dial and silver-dial versions of the watch are secured to the wrist via a blue alligator leather strap by Santoni.
Inside the new Tourbillon Rétrograde Chronograph is the IWC caliber 89900, made in-house by the brand. Like the movement powering its perpetual calendar-equipped sibling, this watch’s automatic mechanism features a gold oscillating weight, though it offers a smaller power reserve of 68 hours.
