I have heard it said mulitple times that the Speedmaster LE bracelet wont fit the FOIS easily for some reason, perhaps to do with hole placement. I would be wary of buying before you are sure. As an experiment, I attempted to fit the Seamaster LE bracelet (which is nearly identical to that on the Speemaster but has different end link markings and possibly a slightly different profile) to my Ed White. This was snug but actually worked. Of course the Ed White is not the FOIS, but it may offer some hope and an idea of how it would look. I haven't kept it on this, was just playing about.
