Not long ago I purchased a Swiss chronograph bearing the brand-name 'Bose'. I was told it was made for the audio company by a well-respected Swiss maker but there's no sign of its origin other than 'Swiss Made'. It's a really nice, professional- looking watch and clearly not a cheap item or giveaway. I've asked Bose but their office couldn't find any trace of it so my question is: does anyone know just who made this watch?
