The prototype is 42mm across and 15.6mm thick, so it's a pretty massive watch – a lot bigger overall than the 40mm 1960s original. The hands, indexes, and dial printing (down to the Heuer-only signature) definitely recall the earlier watch, but there is the addition of a date displayed at 6 o'clock. Surely, the dial would look much cleaner without this intrusion (and it would be more faithful to the original), but there's no question that TAG Heuer will have an easier time selling the watch with the inclusion of the date. FYI – the date wheel here is still sideways as this is a prototype and not a final production watch.

Inside is the Heuer H-03 movement, which TAG Heuer is saying will be introduced in this watch. It's an automatic three-register chronograph caliber based on the CH80 movement (which you may remember from 2014 before the project was killed). It'll be cool to see how this in-house chronograph was adapted to create the H-03 and we'll be paying close attention to the technical details as they're revealed.

This new Autavia will launch at Baselworld 2017 and pricing has not yet been announced, though we're told that it will be in line with other vintage tribute models, such as the Monza and Carrera.
