About this watch
The Omega Speedmaster Professional Moonphase Broad Arrow (model 3875.30.31) is a luxury watch that embodies precision, quality, and timeless design. This piece of history is part of the legendary 'Moonwatch' series, which was first worn on the moon during the Apollo missions. The 3875.30.31 model features the Omega caliber 1866 movement, a handwound chronograph movement that showcases exceptional engineering and precision. The watch's combination of white gold and stainless steel gives it a luxurious yet durable feel, while its sapphire glass provides scratch resistance for daily wearers. With a diameter of 42 mm and a lug width of 20 mm, this watch sits comfortably on the wrist, offering a classic look that complements both formal and casual attire. One of the standout features is its moonphase display at the 12 o'clock position, serving as a functional complication that appeals to enthusiasts who appreciate celestial aspects of watchmaking. The chronograph function allows for precise timing, making it practical and fun to use. The Omega Speedmaster Professional Moonphase is water-resistant up to 50 meters, suitable for everyday activities but not recommended for swimming or diving. This model comes with a sturdy strap that ensures a secure fit on the wrist, complementing its overall aesthetic and offering adjustability for different wrist sizes. At a reasonable weight, the 3875.30.31 feels substantial without being cumbersome, striking a perfect balance suitable for both all-day wear and special occasions.
