SUSTAINABILITY & IMPACT

The highest B Corp score of any watch brand in the world.

108.9

The average business scores around 50. The bar to pass to become a B Corp is 80. 19 months after launch, we became the world’s first watch brand to certify, and today, we’re still the highest rated.

We’re not perfect, and we won’t pretend to be. But everything on this page is real, measured, and just our starting point.

Our mission isn't to make a responsible watch. It's to make the most responsible watch on earth.

We're already further down that road than anyone in our category, and we won't stop until it's a measured fact. Premium solar watches with the lightest footprint we can build, and no compromise on design, quality, or price.

WHAT IT’S MADE OF

Every material had to earn its place.

Recycled Steel

Certified recycled stainless steel. It took us a year and a half to transition, because the industry is full of ‘recycled’ steel that isn’t. So we waited until we found a partner that could prove it.

Eco Vegan Leather Straps

Dropping genuine leather was the easy part. The hard part was not trading down to something cheaper or more harmful. Our silicone vegan leather solves it: zero PU, PVC or solvents, and it holds up to real wear.

Natural rubber straps

Some watches called for a sportier strap, and the usual answer is synthetic rubber made from petroleum. We went the other way. Ours are natural latex, tapped from rubber trees, for the same sporty feel without the petrochemical footprint.

THE BOX

Packaging you keep, not bin.

FSC-certified, 100% recycled and recyclable, made in Montréal on renewable energy. It now comes two ways: the cork pillow, and the Sunseeker set, whose recycled-fibre cloth protected the watch in manufacturing and whose recycled-fiber pouch ships as the pillow, then lives on as a travel case for years to come. More luxury, same standard, less waste.

THE BATTERY YOU WON’T THROW AWAY

One battery. Charged by light. Made to outlast the watch.

A quartz watch burns through a disposable battery on average every 2 years. A Solios runs on one rechargeable battery, charged by the light around you and built to hold over 80% of its capacity for 20 to 30 years. As convenient as it is responsible.

15

disposable batteries kept out of landfill over the life of a single Solios. Zero from your wrist.

Two billion watch batteries are discarded every year. Yours won’t be one of them.

OUR CARBON FOOTPRINT · SCOPE 1, 2 & 3

In 2024, we measured all three scopes for the first time. Then offset every tonne.

Scope 1 and 2 are the easy ones: the energy a company burns and buys. Scope 3 is everything else, the emissions created on our behalf by the suppliers, factories, and freight that make and move our watches. It’s the biggest share, and the part most brands quietly leave off the page.

CCG Climat, an independent climate firm, measured all three across 100% of the business. We then offset every tonne with Verra-verified carbon credits, retired in Solios’s name, in two real projects.

17 t CO₂e

Our full scope 1, 2 & 3 footprint at the time, measured and offset in full.

Verra (VCS)

Credits verified to the world’s leading carbon standard.

2 real projects

Energy efficiency in a Québec community, and rainforest protection in Tambopata, Peru.

ON THE RECORD

Footprint measured by CCG Climat. Offset in full with Verra (VCS)-verified credits, retired in the name of Les Montres Solios.

We did it once, in full, with limited resources. As Solios grows, so will this.

WHAT IT’S MADE OF

The honest part most brands leave out.

B Corp isn’t a trophy. It’s a scorecard that reminds us we’re not finished. Here’s what we’re working on next.

Bringing every collection’s assembly home to Canada, not just the Sunseeker.

Replacing the last parts we haven’t perfected yet, the polymers included, with better materials.

Pushing our footprint lower and our B Corp score higher, always.

We’d rather show you the road ahead than pretend we’ve arrived.

You don't have to choose it because it's sustainable. Choose it because you love it.

Everything on this page comes in every watch we make: the solar movement, the recycled steel, the footprint we measured and offset. Choose the one you love, and the good is already done.
