The Mingzhu DG2812 is an automatic calibre produced by Mingzhu (PTS Resources Limited), a Chinese movement manufacturer. It is a day/date movement featuring a day window at 12 o'clock and a date window at 3 o'clock — a complication layout associated with references such as the Rolex Day-Date. The DG2812 operates at 21,600 bph with 21–22 jewels and approximately 42–44 hours power reserve. The V3 designation refers to the third-generation modification of this calibre by replica manufacturers: adjustments made to case fitment tolerances, rotor stability, and production consistency relative to earlier versions of the same base calibre.
The DG2812 measures approximately 29.0–29.4mm in diameter and 5.45–5.85mm in thickness depending on the supplier variant. It features a quickset day/date mechanism and centre sweep second hand. The V3 designation reflects replica manufacturer modifications to the base calibre — not a Mingzhu factory revision. The core calibre architecture and complication layout remain consistent with the base specification.
In Practice
- The DG2812 V3 operates at 21,600 bph — producing a sweeping second hand motion characteristic of automatic movements. The day/date complication adds both a day window at 12 o'clock and a date window at 3 o'clock, making it the appropriate movement for replica references where both complications must be functional.
- The base calibre carries 21–22 jewels and standard accuracy for this production tier. Actual daily performance depends on regulation quality at the point of assembly by the replica manufacturer.
- Power reserve is approximately 42–44 hours from full wind — slightly longer than comparable automatic calibres in this tier. A watch left unworn over a weekend will typically retain enough reserve to resume timekeeping; a watch left unworn for two or more days will require manual winding via the crown before wearing.
- The V3 designation reflects replica manufacturer modifications to case fitment and rotor tolerances relative to V1 and V2 versions of the same calibre. These are assembly-level adjustments — the fundamental movement architecture and complication layout remain unchanged.
- The DG2812 V3 is a closed caseback movement in practice. For references with exhibition casebacks where movement appearance matters, a clone movement is the appropriate choice.
