If I remember correct, the world precision record was obtained with a 30t2 rg aka chronomètre.
It is the first time I see this box, nice find.
I can´t agree on that. Chronometre boxes are very different!
This box reminds me of the boxes sold with watches to South American countries.
Any of the boxes for sale? I am in England
thanks
