Dead seconds and retrograde date. I considered buying the red gold version available at a dealer nearby, but was never quite convinced with the color combination. The steel version, however, with grey/white dial and blue hands, totally won me over!

I read through La Joux-Perret patents to figure out how the dead seconds work. As far as I understood, the implementation in this watch follows the technique invented by Richard Habring, allegedly reducing the adverse effects on timekeeping accuracy compared to alternative dead seconds methods. My TBR so far runs at a very decent +3 seconds/day.
Dead seconds mechanisms have dubious reputation when it comes to reliability and longevity. This didn't stop me from pulling the trigger, but would love to hear from fellow purists. Is there anyone who has had a long-term experience with this complication, and Richard Habring's invention in particular?
