Dial and Hands

The stainless steel case measures 36 mm and retains its defined lines and sharp lugs. Gentle signs of age are evident in fine surface marks, yet the case is free from deep scratches or dents and preserves its original character and finish. The acrylic crystal remains clear with only minimal, natural signs of use, maintaining excellent legibility.

Movement
Fitted with a robust and recently serviced automatic Seiko movement, this watch demonstrates an excellent timegrapher performance of -2 to +5 seconds per day with strong amplitude, confirming healthy mechanics and reliable vintage performance.
