Double-train trip repeaters became popular around 1900, especially in America. Not many were made due to their complication, and consequently their cost. Patek Philippe made a few for Tiffany, Ekegrén produced a few for Caldwell. Most were minute repeaters and a very few, as in the present watch, were five minute repeaters. Henri-Robert Ekegrén 1823-1896. Was the son of Daniel Ekegrén, of Swedish origin. Henri-Robert became skillful in watchmaking and engraving at an early age. After his apprenticeship he obtained a fellowship to travel to other watchmaking countries. At one point he worked for his fellow countryman, Jules Jürgensen, at Le Locle. In London, he worked for a well-known firm. In Paris, he worked for the celebrated Winnerl and became friendly with Adolph Lange. In 1847 he arrived in Geneva, where he worked with Henri Golay, an expert watch finisher, then with Golay-Leresche. In 1857 he formed a partnership with Ferdinand Westermann. Mr. Ekegrén took as his assistant the young Louis Chevalier, who was to remain with him for thirty-seven years. At the 1867 Exhibition he won a gold medal. Subsequent exhibitions - Vienna in 1873, Paris in 1875, Philadelphia in 1876, Paris in 1878, and Zurich in 1883 - brought him further honors and recognition. He constantly worked to improve each detail and to make a product of the highest merit. His watches are held in high esteem in Europe and America even to the present day.
