Ming 5705 Comet Worldtime Adds a Patent-Pending DST Bezel
Ming has released the 5705 Comet Worldtime, a 200-piece 40mm steel watch that is 10.33mm thick, for the brand’s ninth anniversary. It uses a patent-pending DST bezel with a 15° click, a Sellita-for-Ming 330.M2 movement with a 50-hour power reserve, and 100 metres of water resistance. Prices are CHF 6,950 on leather and CHF 7,950 on Polymesh.
Worldtimers usually fail at daylight saving. Cities jump an hour; the bezel stays put. Ming’s 15° DST click is an attempt to make that jump a tactile adjustment rather than a mental one. According to the brand’s brief, the bezel is patent-pending. That is the industry-news item. Travellers who build GMT mods instead of buying a worldtimer still need a clean 24-hour hand; see the Seiko GMT mod build guide.
Case, calibre and straps
Forty millimetres and 10.33mm is a contemporary sports-dress box. One hundred metres of water resistance is enough for rain and a swim if the gaskets are real. Sellita-for-Ming 330.M2 is a dedicated execution of a workhorse automatic, with 50 hours of reserve—short of a weekend-and-a-bit, long enough for a two-day desk.

Why a 15° DST click is news
A full 360° city ring is 24 hours. A 15° step is one hour. If the bezel can take a single click to jump a city onto daylight saving, the wearer stops doing arithmetic at the airport. Patents pending are claims, not court victories, but the construction is the story: Ming is trying to productise a problem most worldtimers ignore.
Bezel feel is a manufacturing problem. Clicks that are too light drift; clicks that are too heavy fight a 10.33mm case. Aftermarket insert work on dive watches has the same tension. Material and fit notes are in the bezel insert material and fit guide.
Leather versus Polymesh
CHF 1,000 separates leather from Polymesh. That is a strap premium, not a movement premium. Buyers who travel will likely want the mesh-like Polymesh for humidity. Buyers who want a ninth-anniversary object on a shelf may prefer leather. The same split, on very different hardware, is discussed in the rubber vs metal bracelet guide.
Crystal and AR coating will decide whether the worldtime ring is readable in a cabin window. Sapphire is the expected answer at this price; upgrade logic for other platforms is in the sapphire crystal upgrade guide. After any battery-free mechanical service or case opening, 100m is a claim to re-test, not a lifetime sticker. See the water resistance testing guide for the home-build analogue.
FAQ
How many 5705 Comet Worldtime watches will Ming make?
200 pieces, marking the brand’s ninth anniversary.
What is the DST bezel?
A patent-pending bezel with a 15° (one-hour) click intended to handle daylight-saving adjustments on a worldtimer.

Ming’s 5705 is a 200-piece worldtimer whose news is a one-hour DST click, not a new diameter. Forty millimetres, 10.33mm, and a Sellita-for-Ming calibre keep it wearable; the bezel is the argument.
