Zenith made a decisive early entrance into the extraordinary adventure of aviation in the early part of the 20th century. First partnering with some of the greatest pioneers, Zenith subsequently became one of the first onboard instrument manufacturers. Altimeters and onboard watches intended for inflight use were supplied both to the military and to civilian airlines. Today's Pilot collection is a worthy heir to these years of airborne glory and conquests.

Equipped with a high-precision El primero 4054 B movement, produced in house, this model also displays an annual calendar, showing the date, day of the week, and month, that requires just one adjustment per year in the transition from February to March. In a nod to the swiss civil aviation registration system, the letters HB appear on the side of the case, followed by a figure referring to the model's series number.
