What I do know is that the watch was one of the few of this reference to be produced in platinum. The case metal is unpolished, something link that matters to me. The dial is immaculate, indicating no moisture damage, and the caliber 1014/2 movement is gorgeous, link clean, incredibly precise, and wonderfully loud when I wind it every day, fully enjoying such a well-built keyless link mechanism. I also adore the original matching platinum Maltese pin buckle, a must-have in my opinion.
