1960s Grand Seiko 57GS ref. 43999 "AD" dial
| | | mm
The 57GS (originally reference 43999) is the second generation of Grand Seiko and the foundational pillar of the brand's legendary "Grammar of Design." This early 1960s example features the highly coveted "AD" (Applique Dial) marking at 6 o'clock, indicating that the razor-sharp, multifaceted hour markers are made of solid, platinum-plated brass. With its thick, mirror-polished lugs and the iconic gold lion medallion on the caseback, this manual-wind chronometer is a monument to Japan’s mid-century quest for horological perfection.
