Why Collectors Love This
A nuanced take on the Royal Oak, this 4100ST distills the line's architectural steel design into a balanced 35.5mm mid-size format. Its blue dial has aged to gray, giving the watch a softer, more understated character against the sharp geometry of the case and bracelet. An automatic movement with date keeps the presentation clean and practical. At just 7.7mm thick, it wears with the slim, composed profile collectors seek in early Royal Oak examples.
