About Us
The mission behind Mc Onsen's Cybex Collection started long before we became parents. It originated in a crowded town center decades ago—the moment a small hand let go of a father’s coat, and the world suddenly became a sea of giant, unfamiliar faces. That feeling of being lost as a child is a fear that never quite leaves you.

Years later, standing in a sunny park with our own children, we felt that familiar 'heart-stop' moment when they wandered just a little too far out of sight. We realized that while kids deserve the freedom to explore, parents deserve a safety net that actually works.
We didn't just build these watches to be high-quality timepieces; we built the tool we wish we’d had back in that town center.
Vibrant, fun, and reliable—designed to give kids the independence they crave and parents the peace of mind they need."

Innovation Powered by Mc Onsen
Safety shouldn't be complicated, but it must be sophisticated. Every one of our watches features a unique, laser-engraved QR code on the backcase.
This Mc Onsen watch is ensuring a seamless and secure connection when it matters most. When the code is scanned:
It instantly directs the finder to the 'Find My Family' WebApp.
It provides the necessary details to reunite the child with their family.
It transforms a stylish accessory into a powerful tool for protection without unneccessary radiation.

McOnsen is an international brand operating in the fields of technology and innovation.
Founded in Italy, the brand has developed electronic devices, mobile communication products and innovative services designed around people's everyday needs.
At the heart of McOnsen is a simple mission: to create products and experiences that contribute to a greater sense of freedom, well-being and security.
This philosophy has guided the brand since its earliest developments. One of its most important milestones was the launch of the McOnsen Timephone in 2008, an innovative mobile communication device created to combine technology, mobility and personal freedom. The product was introduced to international markets and developed in accordance with applicable international certification standards.
The Meaning Behind the Name
The name McOnsen is inspired by the Japanese word onsen, meaning hot spring.
Japan is home to thousands of natural onsen, often located in peaceful surroundings and closely connected with nature. In Japanese culture, an onsen represents relaxation, balance and a sense of freedom from everyday life.
This idea became part of the inspiration behind the McOnsen brand. The founder associated the experience of using the first McOnsen device with that same feeling of freedom, comfort and independence.
From this connection between technology and well-being, the identity of McOnsen was born.
Innovation designed to make life feel freer.
A History of Innovation
Founded in 2008, Mc Onsen has consistently explored the intersection of technology, design and lifestyle—developing distinctive products and bringing emerging technologies into everyday life.
2008 — The Timephone
Mc Onsen was founded with the development and commercialization of its first Timephone—a pioneering concept that brought together the functions of a watch and a mobile communication device.
The Timephone anticipated a category that, only a few years later, would become familiar around the world through the rise of the modern smartwatch.
2009 — Audio-Vibra Blue Technology
In 2009, Mc Onsen introduced Audio-Vibra Blue technology into consumer products.
The technology enabled sound to be transmitted through solid surfaces using vibration, bringing an innovative method of audio transmission—derived from technologies that had also found specialized military applications—into the consumer electronics space.
2010 — Technology Meets Fashion
2010 marked a new chapter in Mc Onsen's approach to combining technology with personal style.
The brand introduced mobile phones and wireless devices embellished in Italy with hand-applied Swarovski crystals, alongside a Timephone featuring hand-set diamonds.
The same year also saw the introduction of a dual-SIM fashion phone offered in 14 colour variations, combining communication technology with an unusually broad range of personalization options.
Mc Onsen also expanded its activity into the senior mobile phone market, developing devices designed around accessibility and ease of use.
2011 — The Smartphone Era
In 2011, Mc Onsen entered the rapidly evolving smartphone category with a range of dual-SIM smartphones developed in collaboration with GSmart, the mobile communications brand associated with Gigabyte.
The collaboration brought together Mc Onsen's focus on design and product positioning with the technological expertise of an established international electronics group.
2012–2014 — Exploring New Categories
Between 2012 and 2014, Mc Onsen continued to experiment with compact technology and emerging consumer categories.
The company developed fashion phones in limited colour editions, combining extensive functionality with exceptionally compact dimensions.
During this period, Mc Onsen also continued its work in wearable technology and smartwatches, building on the ideas first explored with the original Timephone.
The brand's experimentation extended beyond mobile technology into new lifestyle products, including the development of an early disposable electronic cigarette designed in the familiar proportions and format of a traditional cigarette.
Innovation Without Boundaries
From wearable communication and dual-SIM smartphones to fashion-led electronics and emerging lifestyle technologies, Mc Onsen's history has been shaped by a willingness to explore ideas before they became mainstream.
Technology. Design. Individuality.
These principles continue to define the Mc Onsen approach today..
