Clock slave in working order. I used a Thomas Mercer Marine Chronometer from an observatory as the master clock, connected to a 24V power supply. The name RIO appears on the side of the case, but I couldn't find any references to it in Brazil. I bought the clock in the city of Petrópolis, where the elite and nobility used to spend their holidays because of its milder climate, close to Rio de Janeiro. It was at an auction. Unfortunately, I don't have the manpower to make a suitable case for such a beautiful clock, which resembles a regulator clock. I have video clock working.

The photos are an important part of the description.
