For factors such as insert color and bracelet type, the specific configurations that command higher prices can often depend on the market at the present time. Historically, it was the red and blue "Pepsi" inserts that commanded slightly higher prices, but the collectibility of the all-black inserts has been picking up in recent years since it is no longer an option in Rolex's current GMT-Master II lineup. Similarly, the current stainless steel GMT-Master II has brought a lot of attention back to the Jubilee bracelet, and prices have since picked up a bit for older models on Jubilee bracelets too.
