This is a Schott 654 in Black Cherry. I've had it for about 5 years, and worn probably 20% of the year during that time. I've applied leather conditioner once or twice, but otherwise no extra care. I keep it out of rain. I've noticed that some of the surfaces show wear and I'm wondering if it's unusual wear or just normal distressing that is unavoidable. It's difficult to capture on camera but is clearly visible compared to leather on the inner side which hasn't been exposred to the elements. It shows up in daylight as 'microcracks' and gives the previously rich black cherry colouring a white distressed overlay. I've given some images below compared to the inner side. It's difficult to capture with the camera but it was an expensive jacket so I want to make sure I'm doing whatever I can to keep it in excellent condition.
