As far as my researches reach, i could only find one more comparable example on the internet sold some time ago. The 44mm case (three engraved numbers on the back) is in unpolished condition, dial and hands are 100% untouched. A beautiful orange bakelitbezel in perfect condition gives this very special chrono an even more amazing aura. There is a Valjoux 7736 working inside this piece which was tested and is doing a great job in all functions. This Dugena comes on a greyish natostrap.
