ETA Power Reserve

[highoeyazmuhudee]

when winding up an automatic eta 2836 for the "first time" how many hours does 1 turn of the crown get you? or if you were to wind it say about 40times or until it gets resistant to winding (fully wound).

I think my power reserve on this one from PT is 1/3 of what it should be... also runs about 20 seconds slow, and when run down giving it a light shake causes the second hand to tick back and forth over a 1 second mark

I know they boast around 36hours as spec.

hmm once i cleaned some debris off the barrel arbor with rodico it made a click noise and started ticking instead of just ticking back and fourth.

Rodico brand cleaning putty is something the watchmaker should never run out of. In addition to it's ability to clean small parts, it is useful for wiping bridges and plates of excess oil, dust, and debris, and for 1,000 other uses: holding parts, fishing lost parts out of crevices, standing things up, and lying them down. Rodico is as an excellent cleaning material and is as useful as your imagination. This is a package of two bars.

thanks? i think it was a problem with the barrel not engaging the rest of the gears, now it works perfectly.

Over-oiling the barrel walls can also reduce power reserve by allowing the bridle to slip prematurely.
