The Oris TT1 Engine Date Skeleton Ref. 01 733 7752 4124-07 8 24 08 is an original Swiss Made automatic watch belonging to the TT1 collection, part of the Oris Motor Sport family. The model is distinguished by its characteristic 42 mm steel case, the distinctive black skeleton dial that offers a glimpse of the mechanical movement, and the stainless steel bracelet. The configuration is completed by a sapphire crystal and water resistance of up to 10 bar / 100 meters.

The round stainless steel case measures 42 mm in diameter and approximately 11.60 mm in thickness. The design of the TT1 Engine evokes the world of motorsport, with sporty and technical lines. The crown is screw-down, while the transparent case back allows the automatic movement to be observed. Water resistance reaches 10 ATM / 100 meters.

The characteristic skeleton dial allows a view of part of the watch's internal mechanics. The indices and hands are luminescent, and the minute track is marked along the outer edge of the dial. The configuration also integrates a date display.

The automatic movement is the Oris 733 caliber, based on the SW 220-1, with a frequency of 28,800 vibrations per hour (4 Hz) and a 38-hour power reserve. The movement offers hour, minute, second, and date functions and is visible through the transparent case back.

The dial is protected by a scratch-resistant sapphire crystal, ideal for preserving the readability and aesthetic of the unique skeleton dial over time.

The stainless steel bracelet completes the original configuration of the reference and is paired with a folding clasp with push-buttons. The specified width for the bracelet is 24 mm.

A particularly interesting model for fans of skeleton automatic watches and motorsport, capable of combining traditional Oris mechanics with a technical and sporty design. The TT1 Engine Date Skeleton represents an original choice for those who desire a 42 mm Swiss Made automatic watch with an exposed movement and date display.
