Hope it's alright to link to another forum (no affiliation with it, personally) ... just thought that the watches looked pretty sharp!
A lot of models from the Nataf-era are also being re-issued with new designs (tourbillons and other complications). There has been news of a Zenith El Primero Pilot, Stratos and Perpetual Calendar. The cal. 2572 from the '60s is also being reissued in new models (perhaps in 2012). There are also plans afoot for a 360,000 vph model (not a separate chrono module like the Tag, the integrated base mvmt. would beat at that freq. ... estimated power reserve = 40 hrs).
Some evidence of El Primeros in 2 sizes in the near future - 38mm and 42mm, with the shift in date back to 4:30 for the 38mm models. Also, some talk of refreshing/redesigning the El Primero and launching that new mvmt. in 2015. Ambitious plans indeed ...
