IWC’s Ingenieur Double Chronograph Titanium ($12,700) introduces a svelte new member to a watch family known for its brawn since the 1950s. Dispensing with the collection’s typical soft-iron inner case, IWC designers lightened up the titanium model, which weighs in at just 130 grams and measures 16 mm thick. The revamped ergonomic design in lightweight, corrosion-resistant titanium matches comfort and performance with the addition of the first rattrapante (split seconds) function to the Ingenieur collection. The split-seconds hand, or double chronograph, lets you track two different times simultaneously during a minute period with a second stopwatch hand that splits away from the first with the push of a third button at 10 o’clock.
