I think that any competent local watchmaker would be able to change hands. I don't think it will be necessary to send the watch back to Laco.
As far as working with either Laco or Universo, I'll investigate both possibilities. It seems to me though, that we might want to do this through Laco, for several reasons.IF we can do this without LACOs help, maybe we can contact Universo ourselves? (Need the specs. from Laco, though - diameters, fittings, so on).
First they have all of technical specifications which Universo would need to make compatible hands, and I sure they are very accustomed to dealing with hand makers.
Second, we already have the contacts at Laco, and they have proven very accommodating and responsive with respect to the B-Uhr project, and have gotten back to us with proposed design changes very quickly. The whole thing is going quicker and more smoothly than I would have thought, and if they maintain this level of service, the blued hand project should go just as well.
