This 75th anniversary model expresses the aurora with a green gradation dial. Viewed through the anti-reflective sapphire crystal, the skeleton structure reveals a striking sense of depth, further accentuating the vastness and mystery of the cosmos.

The dial features a modern skeleton design with expanded openwork allowing the mechanical movement to be appreciated in greater detail. The rail-shaped openwork extending around almost the entire circumference of the dial creates a sense of dimension, further enhancing its distinctive character.

The model is equipped with in-house calibre F6F44 offering stable accuracy of +25 to -15 seconds per day and power reserve of over 50 hours. The see-through caseback is engraved with the words “Orient Star 75th Anniversary” and limited-edition serial number.
