Cal. 692 is an automatic movement with small seconds and moon phase indicator. It is closely related to Calibres 670 and 680 in Zenith’s Elite movement family.
Cal. 692 first appears on the Zenith website in 2009, is listed in the 2010 catalog, and is still listed as of 2020. It was used in a variety of Moonphase watches, including the Heritage Star Moonphase and Heritage Ultra Thin Mooonphase.
Technical Aspects of the Zenith Elite Movement
The basic Elite movement measures 11.5 ligne (25.60 mm) diameter and most models are under 4 mm thick, despite a central automatic winding rotor and date complication. A few models used a larger main plate to move the date window outward or to support complications like a running 24 hour ring. The thinnest Elite movement is the hand-winding Cal. 650 at 2.83 mm and the thickest and most complicated is the large Cal. 687 at 6.20 mm.
Unusually, many Elite movements (apart from the 660 and 670 lines) feature small seconds at 9:00, a distinctive feature that differentiates the watches that use it. Some, however, feature central seconds, an adjustable 24 hour hand, a power reserve indicator, and other complications.
All Elite movements use an annular Glucydur balance wheel with a self-compensating balance spring and fine micrometer screw for adjustment. The automatic winding rotor is mounted on ball bearings like the ETA 2892 and originally included a tungsten carbide element for higher winding power. Most Elite movements boast 50 to 55 hours power reserve and all operate at 28,800 A/h.
Zenith Elite 680 and 690: Small Seconds
Cal. 680 was one of the original Elite movements introduced in 1994 and remains in production today. Most of its descendants feature small seconds at 9:00, though Cal. 690 lacks running seconds and the rare Cal. 689 relocates the subdial to 6:00.
