This watch features an in-house IWC caliber (89760) movement and the classic aviator styling. It’s also a great example of IWC reinterpreting complications in new, practical ways (with some help from acquired technology, if we’re being fair). Worldtime and travel time watches can be difficult and clumsy to use, but this one’s extremely easy. Some folks find it too big and/or too busy, and while there is something to both objections, we loved the combination of a chronograph with a great, and unusual, implementation of a dual time zone complication.
