What's with the watches?

I would strongly suggest that the clocks symbolise the oblivion in the Argentinean Patagonia. Just to put this into context, the Patagonia has always been regarded as a "forgetten" part of Argentina, due to its geographical location, lanscape and small population. During the Malvinas war, many young men from the Patagonia died for their country and were soon forgotten by the rest of the Argentinean society. Going a bit further back in time, many folk songs and stories talk about solitude and timelessness of the Patagonia. This is particularly well conveyed in the stories of the Argentinean gauchos whose narrative often has as a central point the theme of solitude and oblivion. Going back to the symbolism of the clocks, basically, I would say that the most clear interpretation is that the director wants to stress that time is existant but irrelevant in this part of the world, somewhat forgotten by the rest of Argentina and the world. Time passes by, and so it goes, but everything else is the same, and it is as if everything passes by in a vaccum. Just one final thought, if a place on earth is forgotten, is time of any importance to the people there?
