It seems like once every month for the last few months I have added to my original post on Ultra/Altitude/Mirus, so, true to form, today I added a fourth family member, an Altitude. You may recall that Altitude were made, along with Mirus, by Ultra at their Morteau factory, Ultras being made at Bescançon.

Does anyone recognise the movement?
