About this entry

Daytona-style multifunction automatic (the title says "Daytona"; the dial reads "Captain Series, Superlative Chronometer, Automatic") with three subdials, a date window at about 4:30 and a "units per hour" tachymeter-style bezel. It is not a chronograph despite the spec list's "Chronograph" feature: the description's dial analysis (model "C8181M") labels the subdials month (at 3), day of the week (at 9) and a 60-second display (at 6), with the pushers at 2 and 4 setting the day and the month; the month subdial has no complications value. Movement: the spec list says "Movement brand: Mingzhu, Movement model: 3836"; no factory spec sheet for a Mingzhu 3836 was found, so only the movement type is recorded. Brand specs: stainless steel case, 40mm, 20mm band width, sapphire crystal, stainless steel band 21cm with a "Bracelet Clasp". Conflicts: the spec list says 10 bar and 12.5mm case thickness, but the description's parameter table says "50M waterproof" and 13mm and a "Waterproof" panel says the index "is up to 50M", so 50m and 13mm are recorded. The parameter table otherwise agrees (sapphire glass, stainless steel case and band, 40mm, 20mm, 210mm). A "Night" image shows the hands and markers glowing. Blue has a polished steel bezel, Black and White a black ring the description calls ceramic, and Golden (green dial) a gold-tone case, bezel and bracelet (plating not described); three-piece links are counted from the photos. The first description image is captioned "2021 New Style" (recorded as the release year). The caseback and clasp are not shown; AR coating, lug-to-lug and weight are not stated. $119.99 for all colours on 2026-10-24, all sold out on 2026-10-25. No independent review was consulted.
