Hi, i think the Modern Mbw 16610 is not perfect but the best base for some modding.
Oem parts won't fit at the first step,for Tube and crown you must drill the hole in the case and retap.
Gen Insert won't fit you must grind down the Insert or the bezel....
The Bracelet has no hollow midlinks like gen....
The Datedisknumbers are too fat,magnification about 3x...
But rehaut is damm good if you can catch a cylindrical one...
Bezel assembly is better than on CN-Subs...
Casematerial is better,i think 440er steel
So you can see not the holy grail,but for a Franken a good choice,you can get even a TW best is also great....
Hope this helps
