Story & Heritage

Founded in 1904, Oris has built its reputation on producing high-quality mechanical watches with a strong focus on independence and innovation. Unlike many Swiss brands, Oris has remained dedicated exclusively to mechanical movements, a philosophy that resonates deeply with collectors.

The TT1 collection reflects Oris’s connection to motorsport and precision engineering, combining durability, functionality, and a bold design language. The chronograph complication adds a layer of technical sophistication, while the exhibition caseback invites the wearer to appreciate the intricate mechanics within.

This model is a testament to Oris’s belief that true watchmaking is not just about telling time, but about experiencing it through craftsmanship and mechanical artistry.

A robust and stylish Swiss chronograph, ideal for enthusiasts seeking both performance and heritage.
