The Rolex Day-Date 40 is larger than the 36mm models and more in-keeping with modern tastes, which trend towards bigger, bolder wristwatches. The yellow gold models within this category have a classy, sophisticated aesthetic and feature the collection's defining qualities, including the presence of both the day and date on the dial. For yellow gold Day-Date 40 models, the available dial colors are black, champagne, white, silver or diamond paved. The golden 'champagne' option is only available for Day-Date models made from yellow gold and is the color choice that creates the most coherent appearance, but the other options will help the dial to stand out more. Index, Roman numeral or diamond dial markers are available on the various models in this category, while bezels will either be fluted yellow gold, or set with diamonds. The fluted bezel helps to reflect light and provide a more shiny appearance, while the diamond bezel adds an extra sense of extravagance and luxury to the timepiece.
