The most widespread movement in Swiss watchmaking
Designed in the 1970s, the ETA 2824-2 powers hundreds of brands: Tissot, Hamilton, Oris, Longines, Sinn, Stowa, Christopher Ward, and a large part of independent micro-brand watchmaking. If you own a Swiss automatic watch between AED 1,000 and AED 8,000, there is a good chance it uses one.
It comes in four grades of finish: Standard, Elaboré, Top and Chronometer. The winder setting does not change from one grade to another.
Thirty-eight hours is short
This is what sets this calibre apart from modern long-reserve movements. Thirty-eight hours means that a watch put down on Friday evening has stopped by Sunday morning.
For a daily wearer, this is not a problem. For someone who alternates between two or three pieces, the 2824-2 is exactly the kind of calibre where a winder makes sense: otherwise the watch will have stopped every time you want to wear it.
The date, and what not to do
The 2824-2 has an instant date change around midnight. The date mechanism starts to engage from around 9pm and stays engaged until 3am.
Using the quick-set date during this window puts strain on parts that are already engaged, and it is a classic cause of damage on this calibre. A winder removes the issue: the date never stops, so you never need to correct it.
The Sellita SW200-1
Since access to ETA movements became restricted, many brands have switched to the Sellita SW200-1, which is architecturally very similar. The settings are identical: bidirectional, 650 to 800 turns per day.
If you do not know which of the two is in your watch, the setting makes no difference.
