The Navygraf initially released in the early 1970s, with its mythical markers shaped in the form of an exclamation mark, is back in an improved version. Formerly waterproof at 200 meters, this new model now offers a water resistance of 300 meters to meet the requirements of contemporary amateurs and professionals of the underwater world. The 39mm case has been completely redesigned and is made of 316L steel with a brushed effect. Iconic and recognizable at first glance with bright yellow hands, the new Navygraf’s indexes and hands are treated with Super-LumiNova offering exceptional readability during day and at night.
MANUFACTURED MOVEMENT
The creation in 2011 of the AMBRE MBP 1000 house movement marks a new development for the brand and for the group. Reliability and performance characterize the brand’s legacy. The caliber MBP100 is a self-winding mechanical movement, made in France, entirely designed, developed and assembled in Morteau within the workshops of the Ambre group.
Equipped with an oscillating mass mounted on a ball bearing rotating in both directions, it guarantees a quick winding of the spring and a 45-hour power reserve. To this efficiency gain is added precision, provided by a regulator whose balance beats at a frequency of 28,800 vibrations per hour.
The stoning totalizes 31 rubies including 2 located at the ends of the axis of the barrel: a technical choice to effectively reduce the friction generally observed at this element on the mechanical movements.
This “house” movement easily passed the so-called “Guillotine” test, subjecting, among other things, the mechanism to a series of shocks on its edge, a guarantee of its solidity.
