ETA 2824 Vintage - Tweaked to Perfection

[systeman]

I acquired an old ETA 2824 movement that was out of a Technos watch. While taking it apart for a thorough service I learned quite a bit about the movement. The keyless works, date change parts, sliding and winding pinions were different to the current ETA 2814-2. The stem was of the helicoidal type - but was missing. I was very lucky to source some. I also changed to rotor for a new Swiss one.

I had great fun in stripping it down and, as this was my first ETA 2824 service, was amazed at the quality of the components.

When I opened the barrel, the spring was almost mint condition, in fact, I think the movement had hardly been used.

Now, after its service and bringing it back to life, I think it's a fantastic movement.

Here are a couple photos and a video of the timegrapher readings. I think I could even improve the -/+ sec/day setting.

 

 

Timegrapher readings for dial side up and crown down. There's not much fluctuation in other positions.

Good job. Amplitude is a bit low for a Swiss mov.t and would make some purists sneer (I'm not one). After one gets great results on the machine the next satisfaction is to wear daily and enjoy a better accuracy than, say, the ubiquitous quartz Miyotas.
