Hi,
have you ever come across this kind of case?
Mine is missing an arm/tensioner on one side, but I’m unsure how to open it.
Have you seen such case?

Hi,
does anyone recognise this bridge layout or know this movement?
The diameter is ~28mm.
Bridge layout is a bit like omega and doxa pocket watch movements.
Without late Dr Ranfft’s database I cannot even find a haystack 🙁
