I favor the 5146 over the 5140. A perpetual is a nice watch to acquire but Patek's 5140 is a bit too small, not size wise but spatially. With my failing eyes, it is just too hard to read without glasses. I prefer the Go Senator Perp. And for the 5146, I prefer the cream dial over the slate. I could see the 5146 as an everyday watch and even if it is not what people would consider an everyday watch, it wouldn't matter. I wear my other Patek, 5111, with blue jeans and sometimes, yes, with shorts! LOL
