The OMEGA Speedmaster is one of the world’s most iconic watches. Used on all six lunar missions, this legendary chronograph perfectly embodies the pioneering and adventurous spirit of the Maison.
Presented on a black leather strap, this platinum model houses the 2019 version of OMEGA’s iconic calibre 321, which retains the characteristics of the original movement. The 42 mm case, fashioned from a special platinum-gold alloy (Pt950Au20), is fitted with a sapphire crystal caseback allowing the caliber to be admired.
The watch also features a black ceramic bezel embellished with a white enamel tachymeter scale, not to mention its black onyx stepped dial enhanced by indexes and hands mostly in 18K white gold. The vintage OMEGA logo is also in 18K white gold. Three unique counters fashioned from lunar meteorite fragments complete the watch’s design. The same meteorite was used in the manufacture of the Speedmaster 50th Anniversary of Apollo 11 Limited Edition in Moonshine\u2122 gold. <\/p>\n","protected":false},"featured_media":65405,"template":"","meta":{"_acf_changed":false},"product_brand":[396],"product_cat":[491,493],"product_tag":[],"product_collection":[441],"class_list":["post-172405","product","type-product","status-publish","has-post-thumbnail","product_brand-omega-en","product_cat-new","product_cat-watches","product_collection-speedmaster-en","first","outofstock","shipping-taxable","purchasable","product-type-simple"],"acf":{"product_is_new":false,"product_not_available":false,"product_related_stores":null,"product_infos":"","product_features":[{"title":"Features","description":"Chronograph<\/b>: The chronograph function is a mechanism for measuring time intervals.
