The first batch of chronographs delivered to the German Bundeswehr in 1967 were 255 pieces, based on the same 14 lignes Valjoux R222 Flyback caliber used in the CP-2 for the Italian Aeronautica Militare (AMI-marked) and Esercito Italiano (EI-marked).

These watches had Leonidas dials and it is unkonwn how many of them survived, as most apparently were scrapped when decommissioned, some were converted to Sinn - we've seen maybe a dozen or less over the years in original condition.

Cases for the Leonidas Bund are very different from the CP-2, the lugs are very similar in shape to the Heuer Bundeswehr then manufactured in a quantity of a bit above 11,000, but incompatible with these, as the R23-based Flyback in the Heuers is 13 lignes and has the asymmetric pushers of this caliber line.

So the watch on auction is basically authentic, but the dial is a sad refinish, finding an authentic one will be far from easy.

Here's a pic showing the "CP-2 Cronometro da Polso No. 2" and the Leonidas Bund on the left, below that the Italy and Germany Leonidas, a Heuer Bund and, sadly not mine, a Heuer Bund Cal. 12 Prototype.
