The biggest novelty for the Rolex Yacht-Master 40 replica watches Ref.116621 is the use of Everose gold in combination with 904L stainless steel. Rolex calls this combination of materials ‘Rolesor’. The first Yacht-Master reference from 1992, 16628, was full gold and had a gold crown as well. For some reason, Rolex chose the bi-color models, including the model I am talking about today, to have a stainless steel crown.The previous bi-color Rolex Yacht-Master was reference 16623 (introduced in 2005), and had a yellow gold bezel and center links. The uni-directional diving scale bezel is made of Everose gold as well as the solid center links of the Oyster bracelet on this Everose gold & Steel Yacht-Master 40 copy watch.
The strange thing is that Rolex defines Rolesor as follows: “the name Rolesor was patented by Rolex in 1933 and has become a true Rolex signature. The concept is simple: the bezel, the winding crown and the centre bracelet links are made of 18 ct yellow or Everose gold (Rolex’s exclusive pink gold alloy); the middle case and the outer links of the bracelet are made of 904L stainless steel.”. Rolex clearly calls the new Yacht-Master 116621 to be “Rolesor” as well on their website. Strangely enough, bi-color Datejust, Submariner and GMT-Master models seem to have a gold crown. I suppose there is a reason for the Rolex Yacht-Master 116621 to not to have one, but to me it is unclear why this is the case.
Everose is Rolex’ own formula for pink gold. According to Rolex copy watches, it is exceptionally durable, polishable (normally, pink gold becomes a bit yellow-ish again after too much polishing) and gives it an everlasting sheen.
