The main highlight of the SIHH 2017 is the Saxon manufacture collection. A really interesting noveltie is the calendar watch featuring an annual calendar, which is a complication that is positioned right in the middle between a usual and a perpetual calendar.
This is the classic and elegant A.Lange und Söhne 1815 Annual Calendar
1815 Annual Calendar
This timepiece has a manually wound movement,analouge date, day and month indications. A moon phase display is integrated in the watch, since it is an annual calendar. It is a classic interpretation of a complication that is useful and elegant. The 1815 Annual Calendar is the second timepiece with the eponymous calendar function and the first Annual Calendar timepiece called SAXONIA ANNUAL CALENDAR was presented in 2010.
The manual winder is an hommage to Ferdinand Adolph Lange. Ferdinand Adolph Lange obtained in 1866 a patent in the United States of America for his development of a crown winder that would replace the hitherto commonplace key-operated winding works. He referred to as “a useful mechanism for winding and setting watches”.
The most fascinating feature of this timepiece is the fast adjusting device. This means that if the watch has not been used for a long time, you can use the button at 2 o’clock, which makes it possible to collectively advance all indications. There are also three recessed push pieces with the function to correct the day, month and moon phase separately. For the first time in a Lange calendar model the additional recessed push piece can seperately advance the date.
The 1815 Annual Calendar comes in two versions- 18k white gold or18k rose gold in a rather small case of 40mm x 10.1mm. Despite the compactness, the latest manually wound calibre L051.3 has a maximum power reserve of 72 hours. This watch model is based of the 3-hand movement, which is visible on the picture. The engine includes all the traditional features oft he brand: ¾ plate decorated with Glashütte stripes, gold chatons with blue screws….This rounds out a movement that is finished with the high standards of the iconic Saxon watchmaking artistry.
Lange 1 Moon Phase
The Lange 1 Moon Phase was added successful in the A.Lange und Söhne watch family feauturing the requested astronomical complication. Now a new movement has been endowed and the moon-phase display is combine with a day/night indicator Even after 50 years there is a lot of mistery when it comes to unlock the secrets of our planet’s companion. Scientists still can not answer questions regarding the origin of the moon.
This mystery keeps humankind interested in our closest celestial neighbour and underpins the fascination of one of the most coveted astronomical complications : the moon-phase display. It tracks the lunar cycle – with an average duration of 29 days, 12 hours, 44 minutes and 3 seconds – so accurately that it takes 122.6 years for the display to deviate from the true synodic period by just one day. The moon orbits against a background
The concept of the arrangement of the display is very new and pretty particular. A moon in the color gold pursues separately its orbit in the foreground. A celestial disc is placed in the back, which is also made of solid gold and it performs exactly one revolution every 24 hours. Because of the interference effect, the color of the times of the day are in various blue shades. At daytime the sky is bright without stars and at night it changes to a dark sky with prominently contrasting laser-cut stars. The moon orbits against the background that is a double day/night indicator, when setting the watch.
The Lange 1 Moon Phase is based ont the Lange 1 movement, that was introduced two years ago. The performance atrributes are the same, which includes the twin mainspring barrel with a maximum power reserve of 72 hours and it contanins the precisely jumping outsize date display.
This watch model is available in white, gold/black, pink gold/argenté and platinum/rhodié case/dial combinations.
