Jaime Trilla was a well regarded Swiss horologist active in Geneva during the late 19th century. He specialized in luxury pocket watches for the international market, particularly affluent Spanish and Latin American clients. Operating during an era of significant technical transition, Trilla’s workshop used remontoir (crownwinding) systems that eliminated the need for a traditional winding key. His timepieces combined durable, high quality Swiss lever movements with elaborately hand engraved, heavy solid gold cases showcasing the finest traditions of Genevan decorative metalwork. Today, surviving pocket watches signed by Jaime Trilla remain scarce and are appreciated by collectors for their historical representation of late Victorian Swiss export craftsmanship.
