Born in Italy, Spinica was designed as a watch for people involved in marine sports such as yachting and free diving, and has always been involved with the world of the sea. As Spinica’s identity and philosophy spread to many people in Japan, we felt a mutual appreciation for our existence with Umi Sakura, an NPO that promotes environmental beautification of the ocean, and decided to leave a tangible testament to this through a collaboration model.

【What is Umi Sakura】 An NPO that has been promoting environmental
beautification of the ocean since December 2005. In order to make the sea off Enoshima in Kanagawa Prefecture a clean place so that the seahorses that once lived there can return, the group is working on monthly trash collections, collaborating with related organizations, and carrying out various educational activities, with “fun,” “experience,” and “experiential” as its key concepts. The biggest feature is the large seahorse graphic in the center of the dial. This is derived from Umi Sakura’s dream of “restoring the beautiful sea where seahorses can live to Enoshima.” Its dignified appearance, reminiscent of a dragon, invites the viewer into a fantastical world of the sea. This graphic is also treated with Super Luminova, and it has a gimmick that makes the seahorse appear mysteriously blue in dark places such as underwater.

The rear end of the second hand is curved to resemble the spiral tail of a seahorse, which symbolizes “eternity” and “infinity,” giving the watch a unique presence.

The dial has a sandblasted finish that resembles the sand on the ocean floor. The gradation, which becomes darker as you go to the outer periphery, evokes the image of an underwater world bathed in faint light, making the seahorse in the center stand out.

Inspired by the famous documentary filmmaker, writer and biologist Hans Hass, there was no more appropriate model for this collaboration in light of his achievements in spreading the beauty and mystery of the sea.

Also, since we are involved in many activities that involve the sea, we were attracted to the practical functions such as waterproofing and excellent quality, as well as the design that reflects these. I felt that the desire to cherish the sea was evident in every aspect of the product, and I felt that we share the same aspirations. I am frankly happy to be able to announce this collaboration model. At Umi Sakura, we have been working for 20 years, focusing on garbage collection, with the goal of “making the sea of Enoshima a place where the seahorses that once lived there can return.” There is no better motif to express our feelings than the seahorse. After asking for multiple retakes, we finally had a dignified seahorse depicted on the dial and case back. This is the best seahorse, which represents our belief that “we will definitely make the sea beautiful!” and our determination to take on challenges, as well as our sense of adventure in the sea. The strap included with the watch is made of r-PET material made from recycled PET bottles, which I feel is in keeping with our philosophy. Twenty years have passed since Umi Sakura began its activities, but the ocean is still not clean, and further measures are needed for seahorses to return. I hope that the thoughtful actions and activities of everyone who supports our activities will continue, and I would like to wear this watch and work even harder at our activities. ” Umi Sakura has been picking up trash continuously since September 2006, without a single month off. We asked them about their thoughts on environmental protection activities. “I love the ocean, so I want to clean it up. The ocean doesn’t need trash. At first, I started the activity by myself, and ‘cleaning up the ocean’ seemed like an incredible dream, but now it has expanded to include tens of thousands of people, and I believe it is a goal that can definitely be achieved. On the other hand, although I work seriously and sincerely, I do not force my ideas on the participants, and I value the feelings and bonds that are born through the experience and sensation. ‘Let’s aim for it! As our slogan states, “The most fun trash picking in Japan!”, we believe that fun is also important for continuing our activities. We have been active for 20 years, but we still feel that there is a lack of knowledge and prejudice about trash picking, environmental activities, and NPOs. It is important to raise interest in the ocean from various angles while being careful not to force it on people, and this collaboration with Spinicaa should be one such approach. We believe that the real battle is yet to come.” A portion of the sales from this work will be donated to Umi Sakura to support their activities.
Spinica will also be participating in the 213th Umi Sakura Garbage Pick-up BLUE, which will be held on Marine Day on July 21st. We will participate in “SANTA Garbage Collection 2025”. At the venue, you can see samples of the collaboration items.
