Produced during the 1990s, the Mk40 combines a full chronograph with day, date, month and 24-hour indications, fitting an impressive amount of functionality into a compact approximately 39mm case.\u003c\/p\u003e\n\u003cp\u003eDespite the number of complications, the dial remains surprisingly balanced and becomes remarkably intuitive once familiar with its layout.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHistory:\u003c\/strong\u003e\u003cbr\u003eThe Mk40 belongs to an interesting period of Speedmaster production during the 1990s, when Omega experimented with complications and configurations beyond the traditional hand-wound Moonwatch. Rather than the familiar three-register chronograph alone, the Ref. 3520.50 incorporated a complete triple-calendar display alongside its automatic chronograph functionality.\u003c\/p\u003e\n\u003cp\u003eThe model was produced for a relatively short period and has subsequently become one of the more recognizable neo-vintage Speedmaster variants. As interest in 1990s Omega and more compact Speedmaster references has increased, the Mk40 has developed a strong following among collectors looking beyond the traditional Professional models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications and Condition:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOverall: Great Condition\u003cbr\u003eCase: Great Condition\u003cbr\u003eCrystal: Clean\u003cbr\u003eDial: Clean\u003cbr\u003eMovement: Excellent\u003cbr\u003eBracelet\/Strap: Original Omega Stainless Steel Bracelet\u003cbr\u003eIncludes: Watch\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOmega Caliber 1151 Automatic\u003cbr\u003eBased on the Valjoux 7751\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eApproximately 39mm Case Diameter\u003cbr\u003eApproximately 44mm Lug-to-Lug\u003cbr\u003e18mm Lug Width\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBlack Multi-Function Dial\u003cbr\u003eCentral Airplane-Tipped Pointer Date Hand\u003cbr\u003eDay \u0026amp; Month Apertures at 12 o’clock\u003cbr\u003eRunning Seconds \u0026amp; 24-Hour Day\/Night Indicator at 9 o’clock\u003cbr\u003e30-Minute Chronograph Counter at 12 o’clock\u003cbr\u003e12-Hour Chronograph Counter at 6 o’clock\u003cbr\u003eCentral Chronograph Seconds\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClosing Note:\u003c\/strong\u003e\u003cbr\u003eThe Speedmaster Mk40 is a fascinating departure from the traditional Speedmaster formula. Its Caliber 1151 manages to combine an automatic chronograph, triple calendar, central pointer date and 24-hour indication within a compact case that remains highly wearable by modern standards.\u003c\/p\u003e\n\u003cp\u003eThe distinctive airplane-tipped date hand and densely functional yet balanced dial give the Ref. 3520.50 an identity entirely its own within the Speedmaster family. With growing appreciation for neo-vintage Omega and increasingly strong interest in smaller, more complicated references from the 1990s, the Mk40 stands as one of the more interesting and characterful Speedmasters of its era.\u003c\/p\u003e","brand":"JDM Horologist","offers":[{"title":"Default Title","offer_id":50980579442931,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/4984\/1907\/files\/SIKUARe_d.webp?v=1788677213","url":"https:\/\/jdmhorologist.net\/products\/omega-speedmaster-triple-calendar-3520-50-mk40","provider":"JDM Horologist","version":"1.0","type":"link"}
