[Rare] Grand Seiko 5641-5000 Tonneau-shaped 18K Solid Gold Case Automatic Winding Overhauled, Manufactured in 1973 Seiko

This is an 18K solid gold Grand Seiko manufactured in 1973.

It is a special model with an 18K solid gold tonneau case featuring a hammered finish.
　

The dial is champagne gold, with the same hammered finish as the case.
It is one tone lighter than the solid gold color of the case, giving it a noble impression.

The movement is an automatic 'Cal.5641A'.
It is the final caliber of the mechanical Grand Seiko, achieving a thin, small, and lightweight design.

This model features manual winding and a hacking function, and is a non-date specification.


While the stainless steel 56GS at the time of its release cost approximately 40,000 yen,
this solid gold model was sold as a top-of-the-line product for approximately 200,000 yen.

It is a rare model with limited distribution, so we recommend it to those who will cherish it.

The case back is a non-waterproof specification that does not use gaskets.
