Just for y'all information. I have the Moonphase Classic Rose Gold.
It has the usual FC705/710
It's been well worn in for over a month. The accuracy is consistently -2.5s/day no matter how much or little activity I do. The winding efficiency seems quite good too, as it holds its power even if I'm not doing much, unlike my old Brietling which can stop overnight.
No change overnight at position 3down, -1s with dial up or 3down.
Runs +1s overnight at 6down. Which is how I shall leave it. Becomes a mini desk clock like that too.
The balance wheel is quite large so it seems to not very much with shocks/vibrations. My eta 2892 watches go off a few seconds when I fly on small rattly planes. The FC is unaffected.
So very good so far.
