up to par?
have you seen any/many of the new reps out of the factory that's making these super reps lately (ie. HBB, chronomat evolution, steelfish superocean, probably EL's iwc 3717)? they are IMPRESSIVE right out of the box far beyond most other standard reps. i think the costeau divers will be no exception.
but to address your other thoughts/concerns:
re: lume, i'm the first one to hope for quality lume on this thing -- i think it is an important part of this rep. will it be super luminova? doubtful. but if the lume is the same quality as EL's 3717, i think i'll be satisfied.
re: servicing the movement, this is a "to each his own" type question. i haven't had any issues with any of my new asian 7750 movements (know on wood) out of the box. if/when i do have any issues, i'll have them serviced, or better yet, put in a genuine eta 7750 (ziggy put the myth that this isn't possible to bed in his post here).
re: new datewheel, the datewheels are very expensive from cousins (maybe $5), and not all of us are that nitpicky....
just my $0.02
