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.
