The 7300-1450 reference in steel makes this replica twenty-4 730014 36mm one of the more accessible entries in the Twenty~4 automatic range. 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.

Technical Overview

• Case diameter: 36mm
• Case material: stainless steel
• Bracelet: integrated steel links
• Crystal: sapphire
• Movement: automatic (324 SC caliber)
• Water resistance: 30 meters
• Functions: hours, minutes, seconds, date

The 324 SC caliber is the same automatic movement found in the men’s Nautilus and Aquanaut, giving this 36mm case the same mechanical reliability that powers the sport watch range. The integrated bracelet tapers from the case to the clasp, following the contour of the wrist rather than sitting flat.

Inside the Movement

Using the 324 SC in a dedicated women’s line was a deliberate choice. Earlier Twenty~4 models ran on the E15 quartz caliber, which kept cases thin but required battery changes. The automatic upgrade eliminated 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 gold version of the same 7300-1450 reference shares identical dimensions and movement but delivers an entirely different wrist presence through its case finish alone.

What Sets It Apart

Steel Twenty~4 models outsell precious metal variants in the genuine market because they accommodate a wider range of daily situations. 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 Philippe positioned this reference as the entry point to the automatic Twenty~4, and it remains the most versatile option in the lineup. This replica twenty-4 730014 36mm delivers that everyday versatility in the collection’s most practical metal.
