Without stones and in steel, this Patek Philippe Twenty~4 Automatic replica in the 7300 style keeps the blue dial, Breguet-style numerals and date at six of the round ladies’ model. A plain polished bezel and a blue sunburst dial make this steel replica Twenty~4 one of the more accessible entries in the Twenty~4 automatic range, as a factory variant of the stone-set 7300/1200A-001. Patek Philippe launched the round automatic Twenty~4 in 2018, moving the collection beyond its rectangular quartz origins into mechanical territory. At 36mm with a steel case and integrated bracelet, this version balances wearability with presence in a way that the smaller 25mm rectangular models never could. Our guide explains why the steel 7300 normally has a diamond bezel.

The clone Cal. 324 S C copies the automatic movement once found in the men’s Nautilus and Aquanaut, giving this 36mm case the same layout that powered the sport watch range. The integrated bracelet tapers from the case to the clasp, following the contour of the wrist rather than sitting flat.

From Battery to Rotor

Using the 324 S C in a dedicated women’s line was a deliberate choice by Patek, and the clone follows it. The rectangular Twenty~4 models run on the E15 quartz caliber, which keeps cases thin but requires battery changes. The automatic 7300 avoids that maintenance cycle while adding the sweep seconds hand and the mechanical heartbeat that quartz cannot replicate. For a visual comparison in a warmer metal tone, the rose gold-tone plain-bezel version shares identical dimensions and movement but delivers an entirely different wrist presence through its case finish and silvery dial.

Blue Dial Without the Stones

Steel Twenty~4 models suit a wider range of daily situations than precious metal variants. The neutral tone pairs with any wardrobe without the formality that gold imposes. Within the full Twenty~4 collection, steel references function as everyday watches rather than occasion pieces. The 36mm diameter hits the current sweet spot for women’s automatics, large enough for easy time reading but not so large that it overwhelms smaller wrists. Patek’s entry point to the automatic Twenty~4 is the stone-set steel 7300/1200A, and this plain-bezel version strips even those stones away for an everyday look. This replica Twenty~4 delivers that everyday versatility in steel, with nothing on the bezel to catch on sleeves.
