About this watch

Omega Speedmaster Moonphase Master Chronometer Chronograph Watch - 44.25 mm Steel Case - Sedna Gold Bezel - Brown Diamond Dial - Brown Leather Strap - 304.23.44.52.13.001

Master Chronometer caliber 9904 drives this sophisticated interpretation of the Speedmaster, combining the legendary chronograph heritage with the celestial poetry of moon phase indication. The 25mm ceramic case of reference 304.23.44.52.13.001 presents an unconventionally compact profile that challenges traditional Speedmaster proportions while maintaining the collection's unmistakable DNA. Sedna gold's warm 18k rose gold alloy creates a striking contrast against the brushed brown diamond dial, where applied indices catch light with subtle brilliance. This Omega Speedmaster 304.23.44.52.13.001 represents a refined departure from the collection's tool watch origins, embracing precious materials and astronomical complications.

“I purchased my first Porsche 911 from Brett. It was my first time purchasing a car without being able to see it in person and Brett made this process easy. He made sure I knew the exact condition of the car prior to finalizing the purchase.”
