THE WATCH THAT PROVED HI-BEAT WORKED In 1967, Seiko doubled the beat rate. 36,000 vibrations per hour. Ten beats per second. They didn’t put this breakthrough in a Grand Seiko — they put it in the Lord Marvel. The Cal. 5740C was the proving ground. It became the foundation for every hi-beat Grand Seiko and King Seiko Chronometer that followed. Only Girard-Perregaux got there first.
Case: SGP gold, 35mm x 41mm lug-to-lug Dial: Original champagne sunburst with applied gold indices and black-topped hour markers. Clean — no moisture damage, no redial. Crystal: Original domed acrylic, minor surface marks consistent with age Crown: Seiko-signed, oversized (~6mm), original Caseback: Horseshoe type, standard markings Lug width: 19mm Strap: Black leather with gold-tone buckle
CONDITION Running and winding smoothly. Keeping time — recommend professional regulation for optimal daily accuracy.
Case shows light wear consistent with age. Lug edges retain definition — not polished into oblivion. This is an honest, well-preserved example.
