From the perspective of someone who does not know about GS you may well be right.
Personally I am getting increasingly jaded with the idea of brand ambassadors, lifestyle positioning (especially when it's of the 'fake it till you make it' kind) etc. The idea of focusing on the watch appeals to me but of course there could be more of a story, even if the attention span at an airport is short 
Maybe it's time for your agency to make a pitch to Seiko?
