WITH THE "ASTRONOMIA SKY" JACOB & CO DID ONE OF OUR DREAMS : TO BE ABLE TO WEAR "THE SKY" ON A WRIST !
First, we want to underline the brillant idea to show the zodiac signs (the stars) and the months on the side of the internal case! It makes totally sense to add together those two complications and the execution is stunning.
Their speed is obviously different as the oval sky indication does a revolution in one day and the months ring in one year.
To set up the timepiece, they came with a simple solution. Each indication has its own setting.
- 2 bows on the case back: one to set the time + the other to wind the movement up
- 2 wheels on the side case: one linked to the months + the other for the oval sky indicator
The axis linked to the seconds is nice. They created a part that has a satellite shape... Quite a Fun touch!
The day/night indication is on the center of the timepiece dividing the earth in two parts. Making a revolution in 24 hours, the tinted half-domed represents the night and the other half, the day.
They choose an amazing Orange Sapphire of 1 carat (288 facets) to show a Red Moon! Adding even more magic to the concept. Their « savoir faire » or know-how is beautifully shown as they applied the JACOB CUT patented technique.
This is a WOW creation without any doubt !
The Time never looks the same and the Sidereal dimension is expressed in a Unique, Exclusive and Beautiful way.
Our Hats off & Applause, JACOB & CO !
