Zenith 689

Cal. 689 is a thin automatic movement from Zenith. Closely related to other Zenith Elite movements, Cal. 689 is the only movement in the family with small seconds at 6:00.

Cal. 689 was used in the limited-edition Zenith Vintage 1955 model in 2008. Just 250 examples were produced.

Technical Aspects of the Zenith Elite Movement

Zenith Elite Cal. 680

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.
