Interra Collection
Your Form. Your Motion.
When the most important terrain you shape is your own, Interra becomes your instrument.
Inspired by the concept of terraforming, this signature collection from Bernhard H. Mayer was made for those who transform worlds, uniting Inter – how you interact and intervene to shape your world – with Terra – Latin for ‘earth’, the world that you shape.
Each Interra is an instrument that shapes your self-expression. The Interra journey begins with the Automatic SS pair, powered by Swiss Sellita SW200 (gents) and SW100 (ladies) movements. While each evolution of Interra is unique in detail, each timepiece in the collection shares the same signature case architecture, embodied in the unmistakable silhouette of the InterraFormaTM Case.
Just as terraforming reshapes terrain through structural intervention, the InterraFormaTM Case reshapes the traditional relationship between case and lugs. Refined over three years until case and lugs were sculpted into one continuous form, the InterraFormaTM Case is an homage to engineered architecture – a circular case shaped by seamless, sweeping lugs into a unified silhouette. Beyond style, these ergonomics also allow Interra watches to sit naturally on the wrist, demanding attention without excess.
Matte and polished surfaces play across each other, accentuated by a polished edge that catches the light and draws the eye to the lugs’ sculpted form. At the centre of each timepiece, where custom-crafted hands keep meticulous time, rests the stylised Bernhard H. Mayer symbol, complemented by a matching logo on the crown of each watch.
Your Form. Your Motion.
Because the future belongs to those who shape their own terrain.
The Interra journey starts here.
Representing the signature architectural form of the Interra Collection, the Interra Automatic SS brings more than 150 years of brand heritage into a single unified design. This limited-edition timepiece is powered by a Swiss Sellita SW200 Automatic movement visible via a sapphire crystal caseback, and paired with a fully integrated stainless steel bracelet with a quick-release system.
At its core is the InterraFormaTM Case – a seamless integration from lugs to case, refined into a continuous, sculpted form over three years of development. This defining silhouette carries across all Interra watches, with exquisite matte and polished finishing that captures both the detail and beauty of Interra.
Handsome open-worked hands with Super-LumiNova move around a custom black dial with date window, accented by sharp lines and angles that are inspired by Interra’s distinctive lugs. These pointed lines further suggest a determined progression of time and motion, moving with you as you transform your world by your interactions and self-expression.
