Zenith

Neuchatel Observatory The Zenith 707 caliber nicknamed internally as the Kartoffel or potato because of its unique shape was designed in late 1961 early 1962 and built in 1963 exclusively for Observatory Competitions to replace the venerable Calibre 135

So in love with this manufacture edition. I do find the new el primero 1969 also nice, and I like the technique of the 1/10th second, but this one gets it all. (More pics inside)

Running with +1 sec/week at the moment. Always impressed by it!

A myth, a legend... Something I saw some 13 years ago, and I missed the opportunity, with big, huge regrets. One of the best manual winding chronometers, here. Best, Nicolas

and an underrated piece IMO. Cheers Fernando

Still one of my favorites. I now own the O.E.M bracelet to go with it.

In yellow gold, the funkiest El Primero I could see, with its tonneau shaped case: Cherry on the cake... Its original strap! Best, Nicolas
