Thank you, it has nothing to do with me I just let it hang around in my bathroom, the steam works a treat At least that is what I tell myself works lol.
Richard the dealers interchange the descriptions all the time. They may advertise A2824 and it is actually a an A2836 and vice versa.
Essentially the difference is a 2836-2 handles the extra Day / Date complication unneeded in a sub with a date only complication. The Asian clones of the two are equally reliable.
I would concentrate more on reading the difference between the VRF and the ARF and not worry about the movement.
What is that? I am in Ireland I never saw it. If it is the thing I am thinking about, ie a big fiery ball in the sky, I heard it can burn you alive. Be careful.
