ETA’s 2896 is a modular movement with “big date”. It is derived from the similar ETA 2892A2 and is part of the third-generation ETA 2890 family. Cal. 2896 appeared in 2004, alongside ETA 2897, and remains in production today.
Unlike many other “big date” movements, Cal. 2896 uses two concentric overlapping discs to display the date at 3:00.
The IWC 30130 is a refinished ETA 2896.
ETA 2890 Family Overview
The ETA 2890 family is a series of slim and robust automatic watch movements produced by ETA since 1975. They are generally regarded as superior to the similar ETA 2800 family. Cal. 2890 and its successors is based on an Eterna design, with ball bearings on the rotor and a smaller balance wheel in the modern style. The family remains one of the leading watch movements to this day.
The most well-known movement in this series today is Cal. 2892A2, a highly evolved automatic movement with central seconds and a date wheel. Because of its slim dimensions, Cal. 2892A2 is often paired with modules to add world time, power reserve indicator, chronograph, and other complications.
Distinguishing features of the ETA 2890 family include a smaller balance wheel than historic movements, including the ETA 2824 family, and a large rotor hub located with seven visible bearings. The balance is located at 12:00 when viewed from the back with the crown at 9:00, and is located by a clockwise cock with an eccentric screw for regulation.
Most members of the modern 2890 family are available in there finish levels:
- Elaboré – with nickel balance
- Top – with Glucydur balance
- Chronomètre – with Glucydur balance and official chronometer certification
ETA also sells these movements with gold plating, various finishes, and custom rotors.
ETA 2890 Family
Most current ETA 2890 family movements have been updated since the 1990s with improved winding efficiency and an extra jewel in the upper winding bridge. As of 2020, ETA is no longer supplying these movements outside the Swatch Group, with most buyers switching to the clone SW300 family from Sellita. Specifically, Cal. SW300-1 replaces ETA’s 2892A2, Cal. SW330-1 replaces ETA’s GMT 2893-1, and Cal. SW360-1 replaces ETA’s small seconds 2895-2.
