Our "Mare" model is made in a stylish design to suit any style. The watch is available in unisex sizes 40mm, 36mm with straps for women and 36mm with straps for men.

Mare is a diver's watch that can withstand being underwater without damage.

The watch comes in 4 different colors: black, brown, blue and green. In addition, there are tons of combinations you can make with our many straps available in both silicone, leather and nato.


Day n' Night

Our Swiss SuperLuminova is powerful as a torch. We wanted to make a watch that can be used everyday in any condition, so whether you’re deep diving with no natural light sources, or cruising the city at night, we want you to be able to use your Oliver Green watch.

FSC Certified packaging


All our watches come with our interchangeable straps, so you can customize the look of your watch by the click of a finger, making sure your watch always matches your outfit, mood and occasion.


Our packaging is made with a multiple purpose in mind. We wanted to create a sleek case that doubles as a transport and a presentation case. This means that instead of the traditional inner box, outer box, plus transportation box, we have one box for all, lowering our materials use drastically. The box is made from premium FSC certified craft paper, with protective pyramid foam inside. To add further protection, we packed every component in recyclable aluminum bags. We believe this is the packaging of the future, and we are already looking to develop this further, with even more eco-friendly materials.

From concept to design

A lot of thought went into designing our Mare model and getting from idea to final design.

The watch is designed in our HQ in Copenhagen by our design team. It is designed from the smallest detail and makes the watch completely unique.

Love the design

I like the dimensions of this watch. The curves overall are so balanced and the depth of the case and the curve of the crystal finish this watch. The watch face is very easy to read and the green bezel contrasts nicely with the flat black dial. I’m very impressed with this watch.

Hi James,

Thank you for all the kind words and for taking the time to leave us a review - it means the world to us! We hope you are still enjoying your watch.

Have a nice day!

Best Regards,
Oliver Green

Simple and elegant

Very nice build on this watch. Functionally, the watch is easy to set and easy to see the time day and night. The interchangeable watch straps are a great bonus. I’m very happy at this price point for this watch.

Black Mare 40mm/Flexible and fast post sales support

The Black Mare 40mm is the first watch I bought, and I couldn't be happier with it.
Super slick and classy design and the metal strap goes super well with it.
At first, I bought the 36mm version but realized it wasn't a good size for my wrist, I contacted the team, and they were helpful and fast at responding. I mailed back the watch and immediately bought the 40mm without any concern. After they received the watch, I was refunded totally, and shortly after, I received my beauty.
I recommend the brand!

Hi Frutuoso,

Thank you for all the kind words! We are thrilled that you are happy with the watch and that we were able to help you out with an exchange.

Have a nice day!

Best Regards,
Oliver Green

Theo S.

I like the design. But 3 complaints.
1. Clown is too small. Poorly made and day and date are difficult to set.
2. Minute track is often not visible.
3. I wanted a rubber strap. Had to buy that seperatly.

I would not have bought this watch knowing all this.
If I could I would sent it back and buy f.e. a Citizen for the same privé. This is not worth 200euros.

Hi Theo,

Thank you for taking the time to leave us a review and for sharing your feedback with us - positive as well as constructive.

First of all, I am happy that you like the design of the Mare watch! Of course, the size of the crown is always a matter of preference - we believe that we have designed a minimalistic divers watch with the crown being of suitable size. Until this day, we have not received any negative feedback about the size of the crown, but we of course respect you personal opinion.

At the moment, we only offer rubber/silicone straps fitting our 39-41mm size watches and therefore not the 36mm you ordered.

You are always entitled to an exchange or refund within 30 days after you have received your package, as long as the item has not been used.

Wishing you a great day and happy holidays!

Best Regards,
Oliver Green
