To start off, I think this is a little too unique. To describe the scent, It smells quite literally like a warm server room with all the metallic wiring OR a freshly used solder station with the steam coming off the PCB, that warm metallic smell + leather/oud + some warm spices is Ganymede. It has absolutely 0 amount of sweetness which makes this fragrance absolutely unforgiving.
Smelling this invokes nostalgia: the moment when you insert a DVD into a warm plastic DVD-Reader with that static TV screen. It smells exactly like that but with extra leather.
Longevity-wise, this stuff is nuclear, I cannot go for more than 2 sprays. More than that can be a bit nauseating, especially in spring/summer. I can't even tell how it changes over time since it is just too strong. At the end of the day, I had to scrub it off...
Will probably will never get a bottle or even a decant because I can't think of any occasion or reason to why I would want to smell like that.
