One of the most common Swiss watch movements, the ETA 2824-2 is the third refinement of the original ETA 2824. Like most ETA movements, Cal. 2824-2 is available in Standard, Elaborate, Top, and Chronometer versions. The similar ETA 2836-2 adds a day wheel. Cal. 2824-2 replaced Cal. 2824-1 in 1982 and remained in production through 2021. After this, only proprietary versions for Swatch Group companies remained in production.
Cal. 2824-2 is frequently re-branded by other companies. Examples include Ball 2050, Frederique Constant FC-303, Glycine GL 224, Jean Marcel JM A05, Nord N3, TAG Heuer Calibre 5, and U-Boat U-28.
Since the patents for the design are expired, there are a number of clone movements. Common ETA 2824-2 clones include the following:
- Ginault 7275
- Hangzhou 6301
- H.K. Precision Technology PT5000
- Liaoning Peacock SL-3000/CL3000
- Sea-Gull ST2130
- Sellita SW200-1
- STP1-11
- Valanvron VAL-24
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.
