I recently boought a 5817ST with the bracelet, and it's becoming one of my favorite watches for daily wear. It has the classic Breguet features (hands and guilloche face), and it's a very readable watch. I was also considering a Panerai Luminor 40mm as this years watch purchase, but decided against it because of its bulk. For me at least, the 5817 is just the right size.
