"Conservation is mostly dedicated to big animals, symbolic ones like tigers ... We are forgetting about the rest, which might be more strategic for everybody. Many small, basic elements of life are dying because of chemical pollution and the changes on the ground. This is more dangerous. So we are engaged in something very tricky."

Making the movie has also transformed Pitiot's eating habits. He now eats less meat. He jokingly says that he has also stopped attacking spiders in his house as he used to.

"It's a small thing. But if 7 billion human do the same, that could change a lot of things. Small stories like this change the world."

The movie is the second documentary project between Omega and GoodPlanet, after the award-winning documentary Planet Ocean in 2012, which focuses on the marine world.

"What impresses me most is the freedom we had, which is something very valuable today. It's very rare to have partners who are able to understand that if something has to happen, everybody has to respect each one's expertise. Our relationship is based on trust and freedom," says Pitiot.

A company should go beyond its products and share its vision, as well as offer monetary support, with the rest of the world, says Jean-Pascal Perret, vice-president of communication and public relations of Omega.

"Many people think that when you share, it comes with a cost. In fact, sharing makes you richer. This experience has made me richer on a personal level, but also the company. So open your eyes and ears and especially your heart while watching this movie," he says.

Omega released its Seamaster Aqua Terra "Good Planet" collection in 2015. Part of proceeds from the sales will support an environmental project in Botswana.
