History
During the 1970s, Longines produced a variety of refined dress watches that embraced bold geometric shapes and textured finishes. The reference 7873 9 exemplifies this design philosophy with its 27 by 27 millimeter square case, slim 7 millimeter thickness, and 35 millimeter lug-to-lug profile. Powered by the reliable manual wind caliber 428, these models were designed to offer elegance and precision in a remarkably slender package. Today, finding an example with its original factory finishes and matching mesh bracelet provides a wonderful window into the refined styling of that era.
