You forgot to add 650usd for a gen bracelet!
You're right.. about the cost..minus the Bezel.. (since it's not possible on a UPO). I think the most common mod is to go with the crown, tube, chief crystal and bezel insert. The dial already looks 110% better just from getting the AR... You can make a GREAT looking franken... for $150-$200usd. obviously adding the gen dial would add to the cost.. but i don't think it's as necessary as the crown, tube and AR.... Just my .02
