Cal. 682 is a thin automatic movement with date and adjustable 24 hour hand from Zenith. Closely related to other Zenith Elite movements, Cal. 682 is the most complicated early Elite movement yet still measures just 3.75 mm in height. Like the similar Cal. 680, and most other Elite movements, Cal. 682 has small seconds at 9:00. A similar movement with central seconds is Cal. 672, and one lacking the date complication is Cal. 693.

The central 24 hour hand is adjusted using a pushbutton located at 10:00 on the outside of the case, giving these watches a distinctive look.

Cal. 672 was an early Elite movement, and has been used widely in Zenith watches between 1996 and 2014. Production ended after 2014 when the early Elite movements were set to be replaced by Zenith’s Cal. 3000 (Sellita SW300) and Cal. 6150 series. Although the company has returned to the Elite series as of 2020, the 24 hour movements have not yet been reissued.


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.
