Swiss ETA Watch Movement Parts List with Images

I thought it might be useful to list down the Swiss ETA watch parts together with an image for reference.

I know from personal experience that whenever I have attended a watch making course the experienced tutors are able to recite each watch part number from memory.

Although watch parts differ slightly from one ETA movement to the next the numbers still stay the same.

Below is a list of all the parts for the very popular movements: ETA 2801-2, ETA 2804-2, ETA 2824-2, ETA 2836-2, ETA 2834-2. This collection should give you a good reference for each ETA watch part number.
