I believe the 1957 reissue is the Broadarrow Speedmaster Co-axial and it has 1957 written on the dial in red.
It has tempered blue hands and markers and comes in a creamy white dial. However, this version has three sub-dials, at least the one I have.
I believe there are a few versions about but the 1957 reissue is a limited edition.
Perhaps some members would add some light on this.
