The 5070 is a well known chronograph but this variant is probably a unique piece. I had the good fortune to get some hands on time with this piece which will be offered for sale at auction. If one looks at the 6 o'clock position, one will see the letters "MSO" arranged to form something of a logo. The most noticeable differences between this and the serial production 5070J would be the brown dial as opposed to the black, the single Arabic numeral 12 in Breguet style, the hand styles and the presence of lume on the hands and the dial. Personally, I really like the changes, especially the elimination of the cut numerals.

The serial production 5070J.

The dial also features a nice sunburst effect.

The calibre 27-70 remains unchanged.
