I rebuilt the Reduced, including the movement AND DD module.
Did you do it yourself or have a watchmaker do it? I'm curious if you had any technical documentation to follow.
I did all the work myself and for the movement I did indeed have the technical guide.
To the OP; someone posted this same question on WUS last week and one DD defender said he had his watch serviced without having anything done to the module and it worked out ok. In the defence of such a strategy, the only part that's going to run at speeds fast enough to require Moebius 9010 (the thin lube) is whatever is driven by the seconds wheel staff, everything else is going to be HP-1300 or thicker (which evaporates/spreads/dissimulates much slower).
