Commentary:
手表 The transaction price of this watch is more than double that of the LOT 283 steel case Royal Oak perpetual calendar. The platinum case and mother-of-pearl dial are one of the reasons. In fact, in my opinion, it is also a perpetual calendar function. If the two let me choose, I will choose the latter. Not to mention the high value of precious metals, but to match the style of the Royal Oak series, platinum is far from the effect shown by the stainless steel case. It’s all about style matching, not value.
