I have been looking for a dress watch for a while (as I have no pressure, the pace is leisurely) and accidentally stumbled upon the Cartier Santos Dumont. A much more minimalist case than the regular Cartier Santos watches, a wonderfully thin Piaget 430P hand wind movement, a very thin case overall and a fairly understated appearance (as far as a Cartier can be that).
Nothing outlandish - no blued hands, exotic materials (standard white gold case)... The secret sign at 7 o'clock and that's about it

Still, a lovely watch, fits like a glove - definitely one that will get into the circle of more likely candidates!
