Cuervo y Sobrinos Watch Robusto 1935 Azul Marino 3161B.1B. The highly versatile Cuervo y Sobrinos Robusto 1935 honours the company’s heritage and is inspired by Cuba’s rich history. It is made adjacent the shores of Lake Lugano and is enriched with Swiss watchmaking expertise. This watch is the best of both worlds or, as we prefer to say at Cuervo y Sobrinos, ‘Born in Havana. Crafted in Switzerland.’
