Awesome "first semester" of releases - I think the star of this release is the new in house QP movement, where all indicators (time, day, month, year, moon, week) can be individually controlled by the crown. A bit different than the IWC - where all indicators move in parallel, or the Moser - which has fewer indicators. This also has the additional effect of increasing the water resistance of the watch!
The skeleton perpetual in BMG is another star - for many was considered the most desirable piece because it represents the last implementation of the 5135 openworked movement (note the 5134 was discontinued with the John Mayer), incorporates the vintage fonts, BMG, and the openworking. While it is definitely outstanding, I much prefer my ceramic openworked

As for the other pieces - more to share but overall, by kicking off with the QP and the XT I think it's overall a return to AP's original savior-faire and technical capabilities - without the "hype" of a collaboration. Recall that AP originally started as a movement maker - and so I expect people will see a lot of that prowess shared this year and the years to come!
Cheers
