As one of the most iconic timepieces in horology, the Speedmaster has played a pivotal role in all six lunar missions, embodying OMEGA\u2019s spirit of adventure and precision engineering.\u00a0This 40.50 mm model reimagines the 1957 original with a sleek stainless steel case and a striking green dial. The rhodium-plated hour markers and signature \u201cBroad Arrow\u201d hands, coated with white Super-LumiNova, ensure exceptional readability. A date window at 6 o\u2019clock, a small seconds subdial at 9 o\u2019clock, and a dual-function chronograph subdial at 3 o\u2019clock offer both functionality and balance.\u00a0The brushed bezel, featuring a blackened tachymeter scale, underscores the watch\u2019s racing heritage, while the caseback showcases an engraving of \u201cSpeedmaster \u201857\u201d alongside a flat sapphire crystal with an anti-reflective treatment.\u00a0Completing the timepiece is a stainless steel bracelet with OMEGA\u2019s patented comfort release adjustment system, offering a seamless fit. At its heart, the manual-winding OMEGA Co-Axial Master Chronometer Calibre 9906 delivers unparalleled precision, ensuring this Speedmaster remains a timeless companion for modern explorers.\u00a0The watch is unworn, in like-new condition, and includes its original box, papers, and warranty dated 2024.<\/p>","protected":false},"excerpt":{"rendered":"<p>Movement: Omega Caliber 9906 Movement Type:\u00a0Manual\u2011winding Power reserve: ~60 hours Features: Anti-magnetic, Chronograph, Chronometer, Date, Master Chronometer Certified, Small seconds, Tachymeter, Time zone function, Transparent caseback Case: Material: Stainless Steel Water resistance: 5 bar (50 metres \/ 165 feet) Crystal: Scratch\u2011resistant sapphire crystal with anti\u2011reflective treatment on both sides Bezel: Brushed Stainless Steel with a [&#8230;]\n","protected":false},"featured_media":4931,"comment_status":"open","ping_status":"open","template":"","meta":[],"product_brand":[133],"product_cat":[36,165],"product_tag":[],"class_list":{"0":"post-4930","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-omega","7":"product_cat-omega","8":"product_cat-speedmaster","10":"first","11":"instock","12":"sale","13":"purchasable","14":"product-type-variable"},"_links":{"self":[{"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/product\/4930","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/comments?post=4930"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/media\/4931"}],"wp:attachment":[{"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/media?parent=4930"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/product_brand?post=4930"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/product_cat?post=4930"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/aercana.com\/it\/wp-json\/wp\/v2\/product_tag?post=4930"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
