Unveiled at Baselworld, the Zenith Doublematic Pilot is an all-new El Primero-equipped timepiece. It not only boasts a chronograph (like the majority of El Primeo timepieces), it also has a 24 city worldtimer and a mechanical alarm. The Doublematic Pilot caliber 4046 is an El Primero in-house movement with world time and alarm functions.

It includes double power barrels, one dedicated to powering the alarm and the other powering all other functions. The hand-decorated self-winding movement consists of 439 parts, 41 jewels, a frequency of 36,000 vph (5Hz), and a 50-hour power reserve. Functions include hours, minutes, seconds, alarm, 24 time zone world timer, chronograph, big date, and alarm power reserve.


Housed inside a stainless steel or 18k gold case, the Doublematic measures 45 mm in diameter. The bezel features a day/night indicator as well as a list of 24 cities for adjusting to the correct time zone. A special power reserve subdial at 7 o’clock indicates how much power is remaining in the alarm’s mainspring; it also displays if the alarm is set to “on or off.”

Comes on a black hand-stitched alligator leather strap. Water resistance is 30 meters. This timepiece represents a nice utilization of the famous El Primero caliber, without being just another Zenith chronograph. Moreover, the additional world time and alarm functionality are highly useful, and the vintage-inspired styling should appeal to consumers who favor classic timepieces. (Ref. 03.2400.4046/21.C721)
