IWC Pilots Chronograph IW371711

The IWC Portugieser Chronograph reference IW371711 represents a modern interpretation of one of IWC s most celebrated and historically significant collections. The Portugieser line traces its origins to the late 1930s when two Portuguese businessmen commissioned IWC to create a wristwatch with the precision of a marine chronometer. This particular reference, introduced in the 2000s, carries forward that legacy of precision timekeeping while incorporating contemporary chronograph complications that have made the Portugieser Chronograph one of IWC s flagship offerings. At the heart of the IW371711 beats the robust Caliber 79320, an automatic chronograph movement based on the reliable ETA 7750 architecture, extensively modified and finished to IWC s exacting standards. This 25-jewel movement operates at 28,800 vibrations per hour and provides a 44-hour power reserve, driving the chronograph functions alongside the time display. The movement features a bi-compax subdial layout with running seconds at 6 o clock and a 30-minute chronograph counter at 12 o clock, complemented by a date display at 3 o clock. The sapphire crystal caseback reveals the movement s refined finishing, including Geneva stripes and blued screws. The 43mm rose gold case presents classic Portugieser proportions with clean, elegant lines that emphasize the watch s sophisticated character. The black dial creates striking contrast against the warm rose gold case, while the silver-toned subdials and applied Arabic numerals maintain the collection s distinctive aesthetic DNA. Notable design elements include the railway minute track, leaf-shaped hands, and the harmonious integration of chronograph pushers that preserve the case s refined profile. This reference occupies a significant position in the collecting community as it represents IWC s mastery of both classical design and modern chronograph complications, making it highly sought after among enthusiasts who appreciate the intersection of horological heritage and contemporary craftsmanship.
