Apple premiered a new ad called "Metal Mastered" during NFL games this afternoon, showcasing the new gold iPhone 5s. The ad, which features the song "Ooh La La" by Goldfrapp [iTunes] and no dialogue, depicts golden liquid metal morphing into the iPhone 5s.

Earlier this week, Apple launched the first magazine ads for the iPhone 5s, also featuring the gold model.

The new ad is very similar to the Plastic Perfected spot for the iPhone 5c that debuted in September

Apple has been heavily advertising the iPhone 5c on television in recent weeks, but we have seen relatively little about the 5s, likely because of tight supplies. The new television spot, in fact, includes a "subject to availability" disclaimer at the end.
