ETA’s 2895-1 is a modular small seconds movement produced from 1997 to 2000. It is based on the ETA 2892-2, part of the second generation of the ETA 2890 family. The replacement, ETA 2895-2, based on the updated ETA 2892A2, was introduced in 1999.
The ETA 2895-1 paired a small seconds module with the ETA 2892-2 base. This increased thickness from 3.6 mm to 4.35 mm.
ETA 2890 Family Overview
The ETA 2890 family is a series of slim and robust automatic watch movements produced by ETA. They are generally regarded as superior to the similar ETA 2800 family. Cal. 2890 and its successors is based on the Eterna 1466U, with ball bearings on the rotor and a smaller balance wheel in the modern style. Launched in 1975, 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.
