I absolutely love Radiomir cases, especially the older models with less sharp case edges such as the legendary PAM021. To me they resemble vintage oysters like this one:
My current radiomir models (062 and 103 both in 40 mm):
PAM062
PAM103
I like these two 40 mm rads (no longer made unfortunately). These are perhaps the smallest and thinnest Pams ever made. Yet, the dial has all 3-6-9-12 and the small second just like the vintage rads driven by the legendary Angelus SF240!
