The watch is equipped with a fixed solid steel bezel with a tachymeter scale, and it includes screw-down pushers and a screw-down winding crown. It is presented on an Oyster bracelet fitted with a blade clasp. The dial displays the date at the 3 o'clock position under a cyclops lens.

The matte black dial contains three silver-toned subsidiary registers featuring concentric finishing.

- Bracelet and Condition
- The watch is accompanied by an Oyster-style bracelet. The auction description reports that this bracelet is correct for the model but describes it as slightly later than the watch head itself. The bracelet utilizes a blade clasp for securing the watch to the wrist. The overall condition of the example is described as strong. The dial is reported as immaculate, and the luminous plots are noted as fully intact, reflecting the preservation of the piece as offered.
- Movement and Functionality
- This reference 79180 belongs to the 'Big Block' series, which represented a shift in the evolution of the Tudor chronograph line. The primary technical advancement noted in this series compared to the preceding Monte Carlo models is the transition to an automatic-winding movement. The watch functions as a chronograph and features a date display. The screw-down configuration of the crown and pushers is a standard design choice within this product family, maintaining the functional intent of the Oyster case architecture.
