I am struggling here, maybe I was a bit strict on the rules! I would have to amend my current collection as I don't have any non-swiss, but I am struggling to think of what I would buy on a leather strap...
Late '50's Rolex Oyster Royal - black face, sentimental value as it was my Dad's, Manual wind, kind of dressy as it has Dauphine hands.
Oris Big Crown Roberto Clemente. White dial, automatic, leather strap, didn't buy it new which limits my third option a bit. Nice summer watch to balance the collection a bit...
3rd one - hmmmm - I would have to buy something new. Probably a blue Seiko Willard would fill the gap, new, tool watch. My other two Oris watches would have to go of course, which is a pity.
Frustrating this...
