Seamaster 1948 reissue (London Olympics or 70th anniversary)

Would consider any version of these limited editions (with or without sub-seconds). This is a retirement gift idea for a (very lucky) colleague: I'm authorized to spend a bit of money but not what I'm seeing these listed for on Chrono24, and I'm concerned that some of the eBay ones are of questionable authenticity. Figured I'd see if anyone's looking to part with one here, before moving on to another idea.
