The Oris TT1 Day Date Ref. 01 735 7752 4154-07 8 24 08 is an elegant and sporty Swiss Made automatic watch belonging to the TT1 collection. The configuration combines a robust 42 mm stainless steel case, a black dial, and an integrated steel bracelet, creating a modern and versatile design. Its main feature is the combined day of the week and date display, while the Oris Calibre 735 automatic movement offers a power reserve of approximately 38 hours. Water resistance is guaranteed up to 10 bar / 100 meters.

Case

The multi-piece stainless steel case measures 42 mm in diameter, with a lug width of 24 mm. The steel case back is screwed down and features a transparent mineral glass porthole, through which the automatic movement can be observed. The construction ensures water resistance up to 10 bar / 100 meters.

Dial

The black dial features a clean and sporty configuration, with indices and hands designed to ensure high legibility. It includes central hour, minute, and second indicators, accompanied by two windows dedicated to the day of the week and date. The day and date display is the distinctive functional feature of the TT1 Day Date model.

Movement

The watch is equipped with the Oris Calibre 735, a Swiss Made automatic mechanical movement based on the Sellita SW 220-1 architecture. The movement has a diameter of 25.60 mm, operates at 28,800 vibrations/hour (4 Hz), and features a power reserve of approximately 38 hours. It offers hour, minute, and second indicators, day and date, with a day and date corrector, fine timing device, and stop-second function.

Crystal

The dial is protected by a sapphire crystal, domed on both sides and treated with an anti-reflective coating on the inside. This solution provides high scratch resistance and improved dial legibility.

Bracelet

Reference 8 24 08 is equipped with an original 24 mm stainless steel bracelet with a folding clasp. The steel bracelet gives the watch a more refined and versatile look compared to the rubber strap version.

The Oris TT1 Day Date 01 735 7752 4154-07 8 24 08 represents a particularly balanced configuration of the TT1 collection, thanks to the combination of the 42 mm steel case, black dial, steel bracelet, sapphire crystal, and Oris 735 automatic movement.
