Description
The dial of the MK40 is what truly captures attention. Set against a slate-grey background, its bursts of red, yellow, and blue create a dynamic, almost playful contrast that remains surprisingly restrained. This colorful design was uncharacteristically bold for Omega at the time and has since become emblematic of the brand’s experimental period in the ‘90s. Collectors often refer to it as the “Schumacher Speedmaster” due to its unofficial association with the F1 legend — a nod to Omega’s push to fuse sport, personality, and precision.
Inside beats the Omega caliber 1151, a modified Valjoux 7751 — a movement renowned for its robustness and versatility. It powers not only the chronograph but also the complete calendar and 24-hour display, offering a power reserve of approximately 44 hours. The movement is housed in a stainless steel case that retains the iconic lyre lugs of the Speedmaster family, giving it a familiar silhouette despite its radically different dial.
At 39mm, the MK40 wears with refined proportions — a rarity among complicated chronographs. Its size, combined with the short lugs, makes it a strong contender for those who want daily wearability without sacrificing horological intrigue.
No longer in production, the MK40 is often described by seasoned collectors as one of the most overlooked and character-rich Speedmasters ever made. For those seeking a Speedmaster with depth — both technically and aesthetically — this reference represents a perfect fusion of Omega’s heritage and its risk-taking spirit of the 1990s.
