I just received my MBK/MBW 1665 GWSD which came with a 93150 hollow mid links bracelet. The bracelet it much lighter and tinnier than the 93250 hollow mid links bracelet on my gen 16610 -- the links are quite a lot thinner, which makes it feel a bit cheap and nasty. Having never handled a gen vintage 1665 I'm not sure if it's supposed to be like that.
The watch itself is amazing, though -- just going through a light modding process (new bezel insert, crown guard shaving, edge rounding etc.). I'll post pics when it's done.
