The calibre, which has a 42 hour power reserve, is housed in a rose gold case that is water resistant up to 3ATM.
It has been 15 years since fine jewellery house De Grisogono introduced its first watches. Since 2000, the company has been part of the select circle of Haute Horlogerie Maisons and has demonstrated its commitment to meet the highest quality standards in the conception, development and production of watches and movements.
This year’s Instrumento builds on many of the brand’s previous designs, and fans of the pieces will not be disappointed by the robust rectangular styling.
The annual calendar gets its name from its ability to run for an entire year with only one adjustment of the date at the end of February.
Its streamlined design and architecture has been completely updated in order to free up as much space as possible to give pride of place to the month and small second counters.
