Adolf Arbenz was a French cutler working in Jougne in the French Doubs, about 30km from Pontarlier, where most of the French absinthe was produced at the time.
Jougne is not that far from "Le Sentier", where Lecoultre was established at the time. It is safe to assume that, indeed, the mechanism is the Lecoultre mechanism.
Therefore, Arbenz used a marketting trick at the time, mainly used in the world of absinthe : the Swiss cross meaning "Swiss quality" (which was the highest grade for absinthe).
I am currently working on mine. A friend of mine (Thaeris) put some ivory scales on it, and I intend to perform a scrimshaw on them, in hommage to my other passion (which is easy to guess at this point).
Of course, the blades are non disposable, and besides the known set, you can find leather purses for the other blades :
