This replica twenty-4 730012 36mm brings the round automatic format that Patek Philippe introduced to the Twenty~4 line in 2018, moving the collection beyond its original rectangular quartz roots. The 7300-1200A reference sits at 36mm in stainless steel, a size that balances presence with proportion on most wrist sizes. Unlike the smaller 30mm rectangular pieces, this round case houses the caliber 324 SC automatic movement, giving it a mechanical heart that matches the rest of the brand’s sport-luxury range. The sunburst dial pattern catches light differently at every angle, shifting between silver and warm grey depending on the environment.

Case & Movement Specs

• Case diameter: 36mm
• Case material: stainless steel
• Shape: round automatic
• Dial: sunburst pattern
• Movement: automatic caliber 324 SC
• Bracelet: integrated stainless steel

The integrated bracelet tapers smoothly from the case, following the same design language established by the Nautilus and Aquanaut lines. Each link is alternately polished and satin-brushed, creating a subtle interplay of textures visible even at arm’s length.

Caliber Breakdown

The 324 SC inside this 7300-1200 is the same base caliber found across several Patek collections, known for its Gyromax balance and Spiromax hairspring in the genuine reference. At 36mm the round case provides ample space for the movement, resulting in a comfortable thickness profile. The automatic winding rotor keeps the watch running during daily wear without manual intervention. For a broader look at the collection, explore the Twenty~4 lineup. You can also compare this round version directly against the 30mm rectangular 4910-1200 version to see how case shape changes the overall character.

How It Compares

The 7300 series essentially redefined what the Twenty~4 means. Where the original 4910 was a jewelry-forward quartz piece, this 36mm automatic stands as a proper mechanical watch that happens to be designed for women. The round case, larger diameter, and self-winding movement close the gap between the Twenty~4 and entry-level Nautilus references. This replica twenty-4 730012 36mm captures that transition point where dressy elegance meets everyday mechanical reliability.
