While I am admittedly not a chronograph guy (the only chronographs I own are digital Casios or an old Breitling Aerospace), I do like the way this watch looks. As an infrequent user of the basic function, I like that Unimatic preserved as much of the style of the U1 while creating a chronograph. That said, you have to be in for the chrono look and function, otherwise, I'd say just get a U1 (of which I am a big fan). The U3's chronograph is powered by a Seiko VK64 Mecha-quartz, which is essentially a quartz movement but with the addition of a hammer and heart-cam rest system identical to what you'd find in a mechanical chronograph; this leads to what feels like a traditional mechanical chronograph when you start, stop, and reset the chronograph. The chrono seconds hand jumps in 1/5 second increments as well to increase the resemblance to a full mechanical chrono. We've seen these hybrid-style movements used in models from Autodromo and other successful brands that want to offer a chronograph without the raw costs and complexity of a traditional mechanical chronograph movement.
