identification of leather club/lounge swivel chair  

hey everyone,

anyone recognise this beauty ? bought it in switzerland and it has an interesting and cool back panel as well as a black section on the feet which is cool even if you can't see it ... but aren't those little details the best part about great design ?  

it also has a scrap of label left under the seat but can only make out a couple of letters. it's in a nice slab font though which, along with the design, makes me think it might be an early piece ? 60s maybe ?

any help appreciated 🙂

cheers
