Both watches share so much elegance and yet have a very different 'feel'. It's really interesting to see them side by side in your beautiful photos. At first glance the 1931 strikes me as being a little sportier, perhaps due to the lume. Whereas the SS seems dressier to me (especially on the factory strap), perhaps because of the polished and faceted hands and hour markers. Though I'm sure both are incredibly versatile. I'm a Burgundy owner too, and whenever I try to look elsewhere (such as a Memovox, Master Ultra Thin, or a different Manufacture), my eyes always wander back to the Tribute Reversos. I am even tempted to add a Blue SS to sit alongside my existing Burgundy. Bravo to you for such a perfect collection!
