Hello Andrey70,

Very nice watch, as always,  moreover, the movement is very unusual, fusee and bridges, a rare piece, it reminds me of the Lépine caliber curved heel, but still different.
The Robert family had many watchmakers, some famous, I watched what I have.

I found just this for James Calame ROBERT here

Hello Andrey70, if you find informations for this watch, I'm interrested.
For me, it's a transition Watch between verge Watch and bridge Watch.
