Im looking to pick up my first rep watch, I really like the breitling Bently "big date" Brown, but it seems to be over $100 more than the model T 30's Bently that looks similar without the wheel back and double date window. Can anybody tell me if there are other differences like if the slide rule is more exact? Im trying to see if it worth $100+ more? Also anyone seen the brown in person how does it compare to the gen? Thanks.
