The stromatolite is a limestone structure formed by the capture and cementation of microbial particles. It is the oldest known fossil on the earth. The oldest stromatolite is 3.5 billion years. Its name derives from the Greek words STROMA substrate (carpet-like covering) and LITHOS (stone).
Dating back to the origin of life on earth, stromatolites are the oldest fossils on earth. Until about 550 million years ago, they might even be the only life forms. The stromatolites help create an oxygen-rich atmosphere, enabling the development of new life forms. They dominated marine life from 3.5 billion to 500 million years ago, and more complex life forms, such as mollusks and crustaceans, brought about their decline in the late Precambrian period.

Louis Moinet and Red Stacked Stone Watch
The red stromatolite used by Louis Moinet is an extremely rare material and now exists only in very few places on Earth. The stromatolites selected this time are from Western Australia and they were found in shoals, saltwater lakes and lagoons that are not suitable for most other organisms. It is formed by bonding and stacking cyanobacteria (commonly known as blue-green algae) and aggregates and develops in temperate aquatic environments, just like corals.
Behind the scenes
Daniel Haas is a world-class expert in selecting and cutting rare gems, with unique skills and knowledge. His work is extremely precise, the deviation is only equivalent to the width of a human hair. The first step in creating a high-quality red laminated stone dial is a series of cuts to select the best part of the fossil. Because the material is quite fragile, it must be handled with care; it also proves that Daniel Haas’ expertise is invaluable.
Perhaps the most striking feature of his work is that it is still a craft, aided by Daniel’s unparalleled skills and unique equipment. He personally made many of the instruments used by himself and his father, some of them for 30 years. Daniel further refined the tools of these artisans, such as diamond wheels and stone cutters, to optimize his work, allowing him to apply the exact amount of pressure required-sometimes almost imperceptibly-determined by his unique feel for the material.

About the red stratolite watch
The natural beauty of stromatolites perfectly combines the mechanical authority of the tourbillon escapement.
The stromatolite surrounds the tourbillon at 6 o’clock and the main air-through mainspring at 12 o’clock. The central hour and minute hands and hour markers contrast with the striking stromatolite.
The laminated stone used in this watch is believed to date back more than three billion years. The stromatolite is dark red, but it is actually formed by the so-called ‘blue-green algae’.
The dial is highly polished and the hand-chamfered three-arm bridge supports the tourbillon to extend vertically to the mainspring visible.
