Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch. It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, in gold on this Day-Date 40.<\/p>\n<\/div>\n<\/div>\n<div class=\"rlx-v7-container rlx-v7-model-section__img\"><img loading=\"lazy\" decoding=\"async\" class=\"rlx-v7-img\" src=\"https:\/\/watchbox-sfcc.imgix.net\/plp-blank.png?w=90&amp;h=90&amp;auto=format,compress\" alt=\"\" width=\"680\" height=\"680\" \/><\/div>\n<\/div>\n<div class=\"rlx-v7-model-section\">\n<div class=\"rlx-v7-container rlx-v7-model-section__content\">\n<div class=\"rlx-v7-body-txt\">\n<h2 class=\"rlx-v7-body-txt__headline\">Blue ombr\u00e9 dial<\/h2>\n<p class=\"rlx-v7-body-txt__body\">The ombr\u00e9 dial features a coloured surface at the centre, progresses to a deep black around the edge. This dial represents the continuity of a design that Rolex introduced in the 1980s and relaunched in 2019. The manufacture of these dials with a concentric gradient involves the application of black lacquer, a delicate operation overseen by a specialist whose task it is to ensure the harmonious transition from colour to darkness.<\/p>\n<\/div>\n<\/div>\n<div class=\"rlx-v7-container rlx-v7-model-section__img\"><img loading=\"lazy\" decoding=\"async\" class=\"rlx-v7-img\" src=\"https:\/\/watchbox-sfcc.imgix.net\/plp-blank.png?w=90&amp;h=90&amp;auto=format,compress\" alt=\"\" width=\"680\" height=\"680\" \/><\/div>\n<\/div>\n<div class=\"rlx-v7-model-section\">\n<div class=\"rlx-v7-container rlx-v7-model-section__content\">\n<div class=\"rlx-v7-body-txt\">\n<h2 class=\"rlx-v7-body-txt__headline\">18 ct white gold<\/h2>\n<p class=\"rlx-v7-body-txt__body\">By operating its own exclusive foundry, Rolex has the unrivalled ability to\u00a0cast the highest quality 18 ct gold alloys. According to the proportion of\u00a0silver, copper, platinum or palladium added, different types of 18 ct gold\u00a0are obtained: yellow, pink or white. They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex&#8217;s commitment to excellence begins at the source.<\/p>\n<\/div>\n<\/div>\n<div class=\"rlx-v7-container rlx-v7-model-section__img\"><img loading=\"lazy\" decoding=\"async\" class=\"rlx-v7-img\" src=\"https:\/\/watchbox-sfcc.imgix.net\/plp-blank.png?w=90&amp;h=90&amp;auto=format,compress\" alt=\"\" width=\"680\" height=\"680\" \/><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Make: Rolex Model: Day-Date 40 Reference:\u00a0228239-0007 Diameter: 40 mm Case material:\u00a018 ct white gold Dial color:\u00a0Bright blue Bezel Type:\u00a0Fluted Bezel Color:\u00a0White Bezel Material:\u00a018 ct white gold Crystal:\u00a0Scratch-resistant sapphire, Cyclops lens over the date Movement:\u00a0Perpetual, mechanical, self-winding Bracelet Type:\u00a0President, semi-circular three-piece links Bracelet Material:\u00a018 ct white gold Clasp:\u00a0Concealed folding Crownclasp Functions:\u00a0Centre hour, minute and seconds hands [&#8230;]\n","protected":false},"featured_media":5380,"comment_status":"open","ping_status":"open","template":"","meta":[],"product_brand":[131],"product_cat":[29,46],"product_tag":[],"class_list":{"0":"post-5379","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-rolex","7":"product_cat-day-date","8":"product_cat-rolex","10":"first","11":"instock","12":"sale","13":"purchasable","14":"product-type-variable","15":"has-default-attributes"},"_links":{"self":[{"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/product\/5379","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/comments?post=5379"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/media\/5380"}],"wp:attachment":[{"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/media?parent=5379"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/product_brand?post=5379"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/product_cat?post=5379"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/aercana.com\/de\/wp-json\/wp\/v2\/product_tag?post=5379"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
