Time leaves its mark. On the objects we take on our travels, on the instruments that accompany us every day, on the materials that change through contact with life. Some watches are designed to keep their original appearance. Others, on the contrary, embrace transformation, making every mark of time part of their identity.

With the ProPilot Date Bronze, Oris takes this second path. The everyday adventure watch from the independent Hölstein manufacture adopts a 41 mm bronze case, a living material whose colour gradually changes with use. Its surface takes on a patina, gains nuance and acquires a singular character unique to each owner.
This new interpretation of the ProPilot Date thus pairs a contemporary silhouette with a material full of personality. A dark green suede strap completes the whole, creating a dialogue between the collection’s aviation heritage, the natural surroundings of the manufacture and the spirit of adventure championed by Oris.
Bronze, a material that tells the story of time
Bronze has a quality that is rare in watchmaking: it does not stay exactly the same over the years. Through contact with air, humidity and daily handling, its surface gradually evolves. A patina develops, revealing shades that give each case a personal appearance.
It is precisely this transformation that gives the ProPilot Date Bronze part of its appeal. The watch is not limited to how it looks on the day of purchase. It is meant to evolve with its owner, to keep a memory of how it has been worn and to develop a visual identity all its own. This evolution is not a flaw but a natural characteristic of the material. Where a uniform finish seeks to preserve a constant appearance, bronze embraces the passing of time and the variations it brings.
Oris thus makes the material an essential part of the watch experience. The patina becomes a story within the story, a discreet trace of the watch’s life on the wrist.
A ProPilot designed for everyday adventure
With its 41 mm case, the ProPilot Date Bronze keeps a size well suited to a watch meant for daily wear. Its identity belongs to the ProPilot universe, a collection whose design language draws on aviation and its instruments.
The aviation spirit can be found in the overall design of the watch, but also in the desire to offer an object made to be worn and used. The ProPilot is not just an evocation of travel: it asserts a functional presence, designed to follow its owner through a wide variety of situations. The choice of bronze adds a further dimension to this philosophy. It introduces a more personal relationship with the object, whose appearance evolves over time rather than remaining frozen.
The watch thus combines a bold aesthetic with a less conventional approach to how materials age. It is aimed at those who appreciate objects that transform and whose character is built up gradually.
A dark green strap inspired by nature
The dark green suede strap plays a decisive role in the aesthetic balance of this new version. Its texture adds a warm, tactile dimension, while its colour echoes the tones of the bronze. Oris links this choice to two sources of inspiration. First, the strap evokes the aviation origins of 1930s design, a period that left a deep mark on the look of cockpit instruments and flying equipment. It also recalls the carpets of moss in the forests surrounding the manufacture in Hölstein, Switzerland.
This dual reference connects the history of aviation with the brand’s natural environment. The deep green of the suede gives the watch a personality that is both understated and adventurous, while the bronze brings the warmth of its material and the promise of change over time. The pairing works as a coherent whole: the strap evokes nature and the origins of the design, while the bronze case gives concrete form to this connection with the living world through its ability to develop a patina.
Oris: the independent spirit of Hölstein
Founded in 1904, Oris is based in Hölstein, in the canton of Basel-Landschaft, Switzerland. The brand cultivates an independent identity and develops mechanical watches tied to different worlds, notably aviation, diving and everyday wear. The ProPilot belongs to this tradition of watches inspired by the world of aviation. Its bronze evolution brings a new interpretation to this identity, focusing on the character of the material rather than on aesthetic novelty alone.
The nod to the forests around Hölstein also anchors this edition in the place where it was created. The inspiration therefore does not come solely from a distant imaginary world: it also draws on the landscape surrounding the manufacture.
With this ProPilot Date Bronze, Oris offers a watch whose personality is meant to build up over time. The bronze will change, the suede will accompany daily life and the watch will keep the traces of its story on the wrist.
Oris ProPilot Date Bronze: time as a personal signature
The appeal of this new ProPilot Date lies in the simplicity of its idea. A 41 mm bronze case, a dark green suede strap and an inspiration that links 1930s aviation with the forest landscapes of Hölstein: a few elements are enough to give this watch a distinct identity.
Bronze brings an almost intimate dimension to the relationship between owners and their timepieces. Its patina develops gradually and varies according to how the watch is worn. The watch therefore never stays quite the same: it accompanies daily life while bearing the marks of its journey. This approach reflects a vision of watchmaking in which time is not read on the dial alone. It also shows in the materials, in the way a watch is used and in the transformations the years leave behind.
The ProPilot Date Bronze is thus a reminder that an adventure watch can tell two stories at once: that of the hours it measures and the one it builds, day after day, with its owner.
The Oris 733 calibre: a proven automatic movement
Behind its black dial, the Oris ProPilot Bronze houses the Oris 733 automatic mechanical calibre. Beating at 28,800 vibrations per hour (4 Hz), this movement offers a 41-hour power reserve and displays the hours, minutes, seconds and date. It can be admired through the transparent stainless steel caseback, which reveals the mechanical components and Oris’s signature red oscillating weight.
A choice consistent with the philosophy of this ProPilot: favouring proven mechanics, perfectly suited to a watch designed to accompany everyday adventures.
