Between a 5907 and a 5920. I've been lurking around here for a while, and this is my first post. I need help to decide which to purchase. This will be my first high end watch and I want to make the right decision. I like the fact that the 5920 shows the date, and the i prefer the look of the dial over the 5907. However, I like how the 5907 has a sapphire case back with the discreet power reserve indicator. What are some thoughts? Also does anyone here know if either of these two come with a deployment clasp? Thanks for any help!
