Hello, everyone! Today's issue: I just cleaned / assembled my first 735...everything looks good, but the watch will stop after just a minute or so...if I remove the balance and pallet, and just 'touch' the sweep wheel, the train is once again free, with good escape wheel recoil ( I made sure of this before putting in balance )..so: what am I missing, and...how may I fix it?! I will say that the 735 is unusually fussy to assemble, but, really, not as challenging as I've heard...then again: thank Heaven for Dumont #5's...!! As always: Thanks! Sincerely, Michael.
