The Master Mariner was LeCoultre's top-of-the-line time only watch in the 1970s. It was designed to be precise, dressy, and water resistant. "HPG" stands for "High Precision Guarantee" and was used to denote the high-beat movement. The present example has an absolutely stunning silver dial with a radial Florentine finish.
