Object description

Case and Dial Design

The Chopard Mille Miglia GT XL reference 8997 is constructed with a 44.5 mm stainless steel three-body case, finished with a polished surface. The design incorporates functional elements such as a protected screw-down winding crown to aid in water resistance, and a glazed case back secured by eight screws, allowing for visibility of the internal mechanics. The sapphire crystal is equipped with an internal magnifying lens, positioned over the date aperture for legibility.

The dial is black and features applied luminous indexes and large Arabic numerals at the 12 and 6 o'clock positions. Further utility is provided by a red-accented minute division and an outer raised 1/5th seconds scale. A central world map motif serves as the backdrop for the 24-hour numerals, which facilitate the second time-zone display. The hands are luminous steel baton types, paired with a distinct central red hand for the GMT function.

The escapement is a straight-line lever type, complemented by a monometallic balance and a self-compensating flat balance spring.
