Ming 57.05 Comet: A Worldtimer with DST Compatibility

Introducing the Ming 57.05 Comet

As Geneva Watch Days approaches, Ming has unveiled the 57.05 Comet, a worldtimer that tackles the perennial issue of Daylight Saving Time (DST) with an innovative two-piece bezel. The watch continues the tradition of decorative worldtimer dials, here featuring a dynamic interference pattern that evolves throughout the day.

The DST Challenge and Ming's Solution

The worldtimer complication, popularized by Louis Cottier in 1931, was already facing obsolescence due to the widespread adoption of DST around 1918. Many brands have attempted to address this, but often with complex or cluttered results. Ming's approach is elegantly simple: a rotating bezel section that can be moved 15 degrees counterclockwise during summer months to align with DST-observing regions. A cut-out reveals a luminous red indicator to signal summer mode.

While not a perfect solution—since DST start and end dates vary globally—the system works for most of the year. For instance, Europe and the US have slightly different DST schedules, but the bezel adjustment covers the majority of the time.

Design and Build

The Comet features a 40mm stainless steel case, just 10.33mm thick, with faceted lugs characteristic of Ming's fifth-generation design language. The two-piece bezel has a brushed finish and notched perimeter, giving it an instrument-like feel. The red DST indicator adds a subtle asymmetry that is both functional and visually appealing.

The dial's centerpiece is the 'Comet Tail'—overlapping striped discs that create a dynamic interference pattern as they rotate. This decorative element honors the tradition of worldtimer dials, which often feature guilloche or enamel maps. The city ring uses a mix of IATA codes (e.g., 'EUR'), airport codes (e.g., 'SFO'), and city abbreviations (e.g., 'TOK'), with a charming nod to Ming's Malaysian roots via 'KUL' for Kuala Lumpur.

Powering the Comet is the Sellita SW330, customized for Ming. It offers 50 hours of power reserve and beats at 28,800 vph. The watch is water-resistant to 100 meters, making it suitable for everyday wear.

Authenticity and Buying Tips

The Polymesh bracelet, priced at an additional CHF 1,000, is a worthwhile upgrade for its comfort and durability.
