I think UN knew if they starved me long enough on the 160 I would crack like a poorly built dam! But I do love that piece, and promise to get you some better pictures.
As for the chronometer, it was made in August of 1957. So, next year will be its 50th! It is a real gem. And it seems great from an accuracy standpoint. When I first got it going, it seemed to start slow but now she is tracking spot on. I estimate the power reserve at almost 53 hours too on a full charge. I will get it to UN early next year for the seconds hand replacement and general inspection, but for now I am most pleased with it
