Fluted crown at 12 o`clock and ring. Double back cover. Needs to be adjusted. This piece belongs to the personal collection of Don Juan José Ontalva (Chinchón, 1930- Madrid, 2019), a famous watchmaker from Madrid, descendant of several family generations dedicated to the world of watches. During his career he achieved a high degree of precision and skill, becoming the master of other watchmakers. He is currently recognised for numerous works, including the commissioning and restoration of the Billeter astronomical clock, located in the Congress of Deputies. Measurements: 3.4 cm. In 1882 Armando Río y Cuervo, together with his brothers Plácido and Lisardo, inherited their uncle Ramón`s watchmaking business. The result of the inheritance was the birth of Cuervo y Sobrinos. From then on, the three brothers worked to make the finest watches in Cuba. The company will work in search of elegance and refinement in all its pieces and in a few years the success of Cuervo y Sobrinos is such that they are forced to open new branches in Germany, France and other countries of the world.
