1. The blue dial looks like the one of 5740G, ie sun burst blue dial with no gradient from periphery to center. My AD said it’s the same dial colour as 5740G, but I find it’s texture is slightly more coarse.
2. The clasp is the new type as 5740. Ie with 4 tiny claws operated by the two side buttons. More secure than the old Aquanaut one.
Best,
Henry
