TT1

The Oris TT1 was originally conceived as a motorsport-inspired timepiece, echoing Oris’s partnership with Formula 1 teams in the early 2000s. Its bold 43mm case, distinctive integrated lugs, and dynamic dial design quickly set it apart as a sporty yet refined choice in the Oris lineup. Collectors value the TT1 for its connection to the brand’s racing heritage and its balance of Swiss engineering with accessible pricing.

Key references within the TT1 range, such as the 01 735 7651 4764-07 4 25 06 (date only) and chronograph variants, differ mainly in movement and dial configuration. The TT1 typically features the automatic Oris Caliber 735 (base Sellita SW 220-1), offering reliable performance and a 100m water resistance that makes it suitable for daily wear. Chronograph versions carry a premium, while limited editions or models with ceramic bezels also command higher prices on the secondary market.

When considering a TT1, examine the condition of the integrated rubber strap and clasp, as replacements can be costly and are specific to this model’s unique case design. Early examples may show dial or bezel updates across production runs, so double-check variant details for originality if collectibility is a priority. Boxed sets and full paperwork can add value, especially for discontinued references or special editions.
