+1 to this. I also think the style of coat is not particularly well matched to the otherwise very sharp ensemble.
Thanks gents. Crusty, your eyes do not deceive - that is a contrast colour button down. It is made by Eton. I picked up two of them at last year's boxing day sale (the second even more, um, out there...) at a local premium menswear outlet. Eton's contemporary fit shirts just happen to fit me like they were custom made, so they dominate my wardrobe. Most are a good deal more subdued, though.
Augustus - that's just a slender fine mesh bracelet - probably doesn't qualify as a dive bracelet - but I like it a change of pace for the summer months.
