Watch has wildly inconsistent performance.  Often stops at less - sometimes much less - than 24 hours.  Watch has been very carefully wound until stem won't rotate any more.  I know it was completely wound.  I would like very, very much to pay the $180 upgrade to get a Florida Diamonds; rather than get this watch back.  I did not understand when I bought the Buenos Aires that a mechanical watch and an automatic watch are not the same thing.  I thought they were different terms for the same thing.  This is my fault - but I would appreciate so much - if you would let me trade-up to an automatic watch.  My preference would be the Florida Diamonds.  Thank you in advance for your strongest consideration.  Mark Petty.
