Teased about on the account of the Patek Philippe Grand Exhibition three days ago, Patek Philippe unveiled its own Instagram account today with a pair of new releases for Baselworld 2018. The first is the ref. 5524R, which is the Calatrava Pilot Travel Time in rose gold with a brown dial, essentially a new look for the original Pilot in white gold launched in 2015.

And the second is almost identical to the first, but smaller. The ref. 7234R is the Pilot Travel Time for ladies is 37.5mm in diameter, in contrast to the 42mm men’s model. Both are powered by the same movement, the self-winding cal. 324 S C FUS. That makes the ref. 7234R the first automatic Travel Time for ladies, with the earlier models having been hand-wound.

The next question then becomes what else will Patek Philippe debut on March 21 when Baselworld opens its doors?

One would expect new models in its bestselling lines, namely the Nautilus and Aquanaut. With the Nautilus range already counting a simple calendar, annual calendar, chronograph, and Travel Time, the only signature complication missing is the perpetual calendar, which means the most logical addition would be, well, a Nautilus perpetual calendar.

And then there is the Aquanaut, arguably the younger, hipper version of the Nautilus. Despite being a sports watch, the Aquanaut line-up still lacks the most obvious of sports watch complications – a chronograph. And since the Aquanaut for ladies is already available in a variety of colours, it might just be time for brighter colours on the men’s models, particularly since the rubber strap allows for a versatile colour palette. So who knows?
