The IW5007-13 was recently added to IWC's Portugieser Automatic collection in 2020. This updated version was first introduced at SIHH 2015 and boasts a longer power reserve of 168 hours, thanks to its two barrels. The Pellaton winding mechanism has also been improved. In terms of design, the changes may be subtle, but they make a big impact in person. The curved glass and ergonomically optimized lugs are the most noticeable differences. The IW5007-13 features a Red Gold case and a Silver dial.
