I’m guessing it’s genuine. Only 32 watches produced and made by Tudor rather than someone just adding some cheap engraving afterwards. It’s commemorative rather than military issue, but someone must have wanted it.
Have any of those Tudor French Military issued watches been sold yet. Can’t remember what it’s called, something like FXD. The shop issue have 4 lines of text and the genuine MI watches only have 2. They will also attract silly money
