I wouldn't change ANYTHING on the 16610 Sub. No.. not even the clasp that feels "cheap and flimsy". I love it just the way it is.
Breitling SteelFish SuperOcean is also very close of being "perfect".
Strong Double-AR
A lot of weight
Comfortable on the wrist
Stunning dial
Very good Pro2 bracelet
45mm size, great for a bigger guy
...and on top of that it's not even expensive in the 2nd hand market.
