ETA’s 2895-2 is a modular movement with small seconds and date. It is derived from the similar ETA 2892A2 and is part of the third-generation ETA 2890 family. Cal. 2895-2 appeared in 1999, replacing ETA 2895-1, alongside the base movement and remained available for sale through 2021. After this, only proprietary versions for Swatch Group companies remained available

The small seconds module adds 6 jewels and 0.75 mm in thickness.

Cal. 2895-2 is also sold as Ball Cal. RR103 and TAG Heuer Calibre 6.

Sellita’s Cal. SW360-1 is a clone of ETA’s 2895-2 but has 31 jewels rather than 27.

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:

ETA also sells these movements with gold plating, various finishes, and custom rotors.

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 2021, 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.
