Description
Specs
This model is equipped with a specially adjusted caliber 9R15, which reduces the average monthly difference of the third mechanism "Spring Drive" to ±10 seconds, in an 18K pink gold case.
This model, which uses carefully selected crystal oscillators that have been carefully selected for aging, can only be produced in small quantities. As a sign of the specially adjusted movement, the oscillating weight is adorned with a lion patch in 18K pink gold.
The dial expresses the image of the snow of the Northern Alps, which can be seen from the Suwa region, the birthplace of Spring Drive, shining beautifully in the sunlight.
The second hand that glides over the white dial gives an impressive impression of the sweeping movement of the original mechanism.
