While technically NOT a complication, please consider this...
Complicated: To build
Complicated: To pay for
Complicated: To service
Complicated: To justify the price to your wife, non-watch lovers
Complicated: To explain how it works (for some)
Complicated: To pronounce (I hear TUR-BILL-EE-YON all the time)
This watch in particular holds some major personal nostalgia points. In the early 2000s, shortly after I first learned about TURBILLEEYONS and horology in general, I took my first ever trip to Europe. At the Breguet Boutique in Place Vendome I can remember seeing this watch in the window and just being in awe. At the time I considered myself way too unworthy to walk in and experience what else the Boutique had to offer. I'll never forget seeing the watch in the window and thinking to myself how unbelievably sophisticated and expensive the watch looked, commensurate with Place Vendome and Paris in general. A far departure from the flip flop wearing beach town I call home. Thanks for posting this one, Nico.
