In Puerto Rico, two birds share the same sky. The pitirre, small, fast, relentless, chases something many times its size. The guaraguao, the island's steady hawk, holds its place, calm and unshaken.

From this came a saying passed down through generations: "A cada guaraguao le llega su pitirre." Every guaraguao has its pitirre. Nothing is too big to be challenged. One challenges. One endures. Both follow their nature.

Batalla en los Cielos is our fully custom line, four automatic pilot watches built around the character of these two birds. Each is forged from surgical-grade 316L stainless steel, fitted with flat sapphire and Super-LumiNova Grade A, and because we're an island, built with 300 meters of water resistance. Every caseback is engraved with artwork by local artist and Santurce Collection co-founder Anita, and every watch is assembled in the U.S.A.
