It's a beautiful piece, and a great replacement. I recently did exactly that by trading an IWC Spitfire Chrono, added money and got a mint master calendar. Wear it in the best of health. Best Regards, kas

Gentlemen, Does anyone know what the engravings on the rotor of a RO 15300 represent? There are two groups of 3 stars, a standing horse holding a sword or is that a cross?, a bird, and some other engraving that I could not make anything of it. Please let me know if you know the answer. Best Regards,
