Omega Speedmaster Moonphase (304.23.44.52.13.001)

The Omega Speedmaster Moonphase (steel / 18K rose gold) 304.23.44.52.13.001 is an exceptional chronograph that blends the legendary heritage of the Speedmaster collection with the elegance of a moon phase complication and modern Master Chronometer technology. This model represents a luxurious, more refined interpretation of the iconic Moonwatch—retaining the sporty character of the Speedmaster series while offering a more exclusive aesthetic and advanced mechanics. It is a timepiece designed for those who appreciate both the prestige of classic design and the innovations of modern Swiss watchmaking.

The 44.25 mm case is crafted from stainless steel and 18K Sedna™ Gold—Omega’s signature rose gold alloy known for its superior resistance to fading. A combination of brushed and polished surfaces creates an elegant contrast that underscores the model’s luxurious character. The brown ceramic bezel, featuring a tachymeter scale in Ceragold™, pays homage to the Speedmaster’s motorsport heritage while lending the watch a modern aesthetic. A sapphire crystal with anti-reflective coating on both sides ensures excellent legibility, while the transparent caseback allows the in-house movement to be admired. Water resistance to 100 meters enhances the watch’s versatility, making it suitable for comfortable wear during everyday activities.

The deep brown sun-brushed dial catches the eye with its elegant color scheme and wealth of detail. The applied indices and hands, crafted from Sedna™ Gold, are coated with Super-LumiNova to ensure excellent legibility, even in low-light conditions. The distinctive twin-subdial layout features a combined chronograph hour and minute recorder at 3 o’clock, and a small seconds display paired with a date indicator at 9 o’clock. Positioned at 6 o’clock is a precise moon phase display crafted on metallized mineral crystal; its remarkably realistic depiction of the moon has become one of the model’s most signature features. The collection’s tachymetric character is preserved through a prominent bezel scale and a dynamic display layout.

At the heart of the watch lies the in-house Omega Co-Axial Master Chronometer Calibre 9904 automatic movement. The movement features a Co-Axial escapement, a column-wheel mechanism, and a silicon balance spring, ensuring high precision, durability, and resistance to magnetic fields of up to 15,000 gauss. It operates at a frequency of 28,800 vibrations per hour (4 Hz) and offers a power reserve of approximately 60 hours, thanks to the use of twin mainspring barrels. METAS Master Chronometer certification attests to its exceptional accuracy and resilience in everyday use. The chronograph function operates smoothly and precisely via the column-wheel mechanism, while the moonphase complication has been designed with meticulous attention to detail and realistic display.

The model features an elegant brown alligator leather strap with stitching color-matched to the dial and bezel. A folding clasp ensures security and exceptional wearing comfort, while the well-contoured case allows the watch to sit comfortably on the wrist, despite its substantial size. The combination of sporty proportions and a luxurious finish makes this model perfectly suited for both everyday wear and more formal attire.

The Omega Speedmaster Moonphase 304.23.44.52.13.001 is designed for the man seeking a luxury chronograph with a distinctive character—one that blends the Speedmaster legend with the elegance of a moon phase complication and modern Master Chronometer technology. This model offers superb craftsmanship, impressive mechanics, and refined styling, all while remaining true to the sporty spirit of one of the most iconic collections in watchmaking history.
