Cal. 2801-2 is a hand-winding movement from ETA. It is based on the design of the ETA 2800 family, and is very similar to the ETA 2804-2, which includes a date complication. This is the only current automatic movement with no date sold by ETA. This movement has been in production since 1983, but as of 2022, Cal. 2801-2 is officially listed as “phased out” by ETA.

Sellita sells a similar movement, Cal. SW210-1, though it has 19 jewels instead of 17.

Current ETA 2800 Family

The ETA 2800 family currently consists of six movements in production since 1982. They are compact but not particularly slim automatic movements operating at 28,800 A/h. The basic Cal. 2824-2 and 2836-2 are among the most widely-used movements in modern Swiss watches. Although over 5 dozen different movements in this series have been produced, just six are available today. Due to restrictions from Swiss COMCO regulations, ETA is unable to sell movements outside the Swatch Group since 2020. This has forced many watch makers to turn to the similar Sellita SW200 series of movements.

Calibres 2801-2, 2824-2, and 2826-2 are officially listed as “phased out” by ETA after 2021, leaving just Calibres 2804-2, 2834-2, and 2836-2 available for sale. This is in keeping with ETA’s focus on proprietary movements for Swatch group companies rather than outside customers.
