Compare the price of this time-only release at link $69,000 to AP's offerings ($54,700 for the 34mm black Ceramic at one end and $101,100 for the double balance wheel openworked on the other, more complicated end), and it feels like it nestles in a good sweet spot. Plus, if you're trying to keep things matchy-matchy with your brown canvas link Neverfull, you gotta have one, right? I'll hold out link for the black one to pair with my Damier Graphite watch roll, which I don't need but still (really) want.

This is an extremely expensive thing to do. If you don't quite have an industrial giant's link budget you do have another choice Find some new-old-stock vintage movements fix them up so link they'll be a source of pleasure and not aggravation put them link in vintage-adjacent cases with vintage-adjacent dials and cross your fingers.
