4400 AS

About the Vacheron Constantin 4400 AS

It is 28.6 mm across with 21 jewels and a beat of 28,800 vph, and its single barrel holds 65 hours, which is long for a hand-wound movement of this size. The small seconds suits the classical dials it is made for, the Traditionnelle with its railway track and the American 1921 with its angled numerals.

In the library it powers 11 Traditionnelle Small Seconds references at 38 mm, 7 Historiques American 1921s at 40 mm and 36.5 mm, and 4 Maltes. One is a limited edition.

The 4400 is the same movement without the seconds, the 1400 the smaller hand-wound caliber, and the 4400 QC and QCL the versions with a full calendar in the Historiques Triple Calendrier.
