About this watch
The Omega Railmaster 220.12.40.20.03.001 is a masterpiece of engineering, boasting a stunning blue dial with a matte finish that exudes sophistication and elegance. Its 40mm diameter strikes the perfect balance between boldness and refinement, while the stick and dot indexes enhance visibility without compromising the minimalist aesthetic. Equipped with a sapphire crystal, this watch is both scratch-resistant and durable enough for daily wear. At its core lies the Omega caliber 8806, a self-winding movement that's a testament to precision and reliability. With a power reserve of 55 hours and Master Chronometer certification, this watch performs exceptionally well under various conditions, including magnetic fields up to 15,000 gauss. The Co-Axial escapement reduces friction between parts, leading to greater accuracy and longevity.
