The Royal Oak Perpetual Calendar showcases a striking contrast between its 18-carat pink gold case and bracelet and the blue hues of its dial. The blue dial’s  Grande Tapisserie  pattern is complemented by blue counters and a blue inner bezel, while the pink gold-applied hour markers and Royal Oak hands with luminescent coating enhance its readability. This elegant timepiece is housed in a glare-proofed sapphire crystal case and is water-resistant to 20 meters.
