Soprod P024

A three-hand date movement, read through an identified watchmaker's specification rather than assumptions about interchangeable calibres.

The P024 is represented here through a specific watchmaker's documentation. Hanhart lists the Soprod SOP P024 as one movement option for its PIONEER One, with three hands, a date display, 25 jewels and a 4 Hz frequency. The watch specification gives 38 hours after full winding. Hanhart PIONEER One technical data.

A named variant matters

The same page also lists a Sellita alternative. That tells us what Hanhart offers in this watch; it does not establish that either movement can be dropped into any case built for the other. Dial feet, hand fittings, stem height, calendar alignment and the manufacturer's complete assembly still need to be checked.

Likewise, Hanhart's named P024 version should not be used to assign identical finishing or adjustment to every P024-powered watch. A calibre name is a useful starting point, not a complete specification of the finished object.

In the atelier

P024 is the straightforward automatic three-hand/date choice, not a stock power-reserve-display movement. If you choose the builder's separately identified reserve-display concept, that represents a proposed mechanism rather than an added function certified for this Soprod calibre.

The graphic uses its selected calendar layout and winding family to organize the watch. Its rear components are illustrative; they are not a parts-ordering reference, material simulation or proof that every case and dial combination can be manufactured. Reserve text does not track winding energy, and decorative choices do not change accuracy. Compare the SW200-1 for a related design role without assuming universal interchangeability.
