Worldtimers are brilliant until daylight saving time gets involved.
With the 57.05 Comet, Ming has taken that familiar inconvenience and turned it into the central idea of the watch, using a patent-pending bezel system that separates cities that shift their clocks from those that don’t.
It’s also a more approachable return to the complication for the independent brand, pairing a stainless steel case with a Sellita-based automatic movement and a deeply animated dial treatment.
At a glance
- Ming has introduced the 57.05 Comet, a 200-piece limited-edition worldtimer with a daylight saving time adjustment system.
- A rotating outer city bezel advances DST-observing locations by one hour while non-DST locations remain fixed on the inner bezel.
- Orders open on 27 August 2026 at 1:00 PM GMT, priced from CHF 6,950 before taxes.
A worldtimer built around daylight saving time
The clever part of the 57.05 Comet sits at the edge of the dial.
Instead of placing every city on one fixed ring, Ming splits the worldtime display into two layers, with locations that don’t observe daylight saving time on a fixed inner bezel and DST-observing cities on a separate rotating outer bezel.
When the season changes, a single click moves the relevant cities forward by one hour against the 24-hour scale.
The mechanism locks into position with a spring-loaded ball and matching recesses, while an aperture near 9 o’clock shows the selected setting in silver for standard time or red for daylight saving time.
It’s a neat answer to a real-world problem, especially for travellers who regularly cross time zones or work with multiple markets.
The Comet Tail dial and fifth-generation case
The name nods to the de Havilland Comet, the first commercial jet airliner, but the dial is where the aviation romance becomes more abstract.
At the centre, overlapping raster structures create a shifting interference pattern Ming calls the Comet Tail.
As the layers move in relation to one another over the course of the day, the dial changes character rather than sitting still.
The 24-hour worldtime ring is finished in blue and black for day and night, with blue-emission Super-LumiNova X1 for daytime hours and orange-emission Super-LumiNova X1 for the nighttime section.
The hands glow blue, while the DST ON indicator emits red light in darkness when activated.
The 40mm case is made from 316L stainless steel and belongs to Ming’s fifth-generation design language, complete with the brand’s triple-stepped lugs.
Those lugs are more involved than they first appear, requiring nine separate components for their construction.
Sellita power and a more attainable Ming worldtimer
Inside is the Sellita for Ming calibre 330.M2, an automatic GMT movement running at 28,800 vibrations per hour with an approximately 50-hour power reserve.
The movement is visible through the sapphire caseback and has been treated with skeletonised brushed bridges, anthracite coating and an anthracite-coated baseplate.
This is a different proposition from Ming’s higher-end worldtimers, bringing the concept into steel and using a movement architecture that helps keep the price below the brand’s more elaborate executions.
The watch is offered on a cobalt-blue goat-leather strap by Jean Rousseau Paris with quick-release spring bars and Ming’s flying-blade tuck buckle with micro-adjustment.
A version on Ming’s titanium Polymesh bracelet is also available.

The 57.05 Comet is appealing because it doesn’t treat the worldtimer as a solved format.
By addressing daylight saving time with a mechanical interface that’s simple to use and easy to read, Ming has given frequent travellers and complication-minded collectors a watch with genuine practical intent behind its visual theatre.
