I will re-exhibit because some photos of different products were mixed in the photo. I apologize to those who were bidding last time.

【Overview】
This is the legendary Grand Seiko 2nd Generation (Ref. 43999 / 57GS), one of the most significant pieces in Seiko's history. This specific example features the highly coveted "SD" (Special Dial), indicated by the 8-pointed star logo at 6 o'clock, which signifies that the hour markers are made of solid 18K gold.

【Condition Details】
• Dial: Original silver sunburst dial with the prestigious SD (Special Dial) star logo. It has a beautiful vintage patina that confirms its authenticity.
• Case: Iconic 57GS "Self-Dater" case with powerful, thick lugs. It retains its strong presence and "Grammar of Design" aesthetic.
• Case Back: Features the rare and desirable Gold Lion Medallion in excellent condition. This is a hallmark of early high-grade Grand Seikos.
• Movement: Caliber 43999, 35 jewels, manual wind. High-beat chronometer grade. It is currently running and keeping time.
• Crystal: Original-style crystal with some light surface marks consistent with age.

【Why This Piece?】
The 43999 is the first GS to feature a date function and a chronometer-certified movement. Finding one with an SD dial and a well-preserved Lion medallion is becoming increasingly difficult. This is a true museum-grade investment piece.
