Story: Founded in 1892 by Robert and Charles Ingersoll in New York, Ingersoll Watch Company quickly became a pioneer in making quality timepieces accessible to the public. Their mission was clear — to bring precision and reliability to every wrist without compromising style or craftsmanship. The brand gained worldwide recognition for its ingenuity, having produced some of the first mass-market pocket watches and even being associated with Theodore Roosevelt, who famously referred to his Ingersoll as “The watch that made the dollar famous.” The Big Date Open Heart pays homage to this legacy. Combining classical watchmaking design with modern automatic engineering, it celebrates Ingersoll’s enduring philosophy — innovation for everyone. The open-heart feature symbolizes transparency and motion — allowing the wearer to witness the living heartbeat of time. This model’s dual-tone case, big date complication, and visible mechanics make it an elegant statement piece, perfectly suited for collectors and enthusiasts who appreciate both heritage and function. A timepiece that bridges American watchmaking history with contemporary elegance, the Ingersoll Big Date Open Heart is more than a watch — it’s a mechanical story of progress, endurance, and timeless design.
