Omega Speedmaster Triple Calendar | Day-Date | 39mm Blue Dial | Ref 3523.80 I

The Omega Speedmaster Ref. 304.30.43.52.06.001 is one of the most striking modern Speedmasters, blending the Moonwatch’s space heritage with a true celestial design. The galvanic grey meteorite dial gives each piece its own unique natural pattern, while the blue ceramic bezel and blue accents add a clean, modern contrast that feels sporty, luxurious, and unmistakably Omega.

What makes this watch special is the moonphase display at 6 o’clock, which features two moons made from genuine lunar meteorite, representing the moon as seen from both the northern and southern hemispheres. It is the kind of detail that makes the watch feel far more special than a standard chronograph—beautiful to look at, technically impressive, and deeply connected to Omega’s lunar legacy.

Powered by the Omega Co-Axial Master Chronometer Calibre 9914, this Speedmaster offers serious modern performance with a manual-wind chronograph movement, 60-hour power reserve, METAS certification, and strong anti-magnetic resistance. The result is a watch that feels collectible, wearable, and visually unforgettable—perfect for someone who wants a Speedmaster that stands apart from the traditional Moonwatch while still carrying the same space-driven DNA.
