???? Why We Chose APSF for this Model?

Many clients ask: “What makes APSF’s frosted gold 26240 better than other factories?”

Here is the honest truth: While other factories offer basic gold plating, APSF excels in replicating AP’s proprietary frosted finish—the most distinctive feature of this modelAudemars Piguet. Additionally, APSF wins in terms of movement integration and case thickness, which are critical for the 26240 Chronograph’s wearing experience. The frosted texture requires exceptional craftsmanship to replicate, and APSF’s version captures the subtle light play and tactile quality of the genuine hammered gold finish far better than competitors who often use flat or poorly textured gold platingAudemars Piguet.

Full Disclosure: Being a heavy plated watch with a frosted finish, we recommend treating it with care to avoid deep scratches that could damage the delicate textured surface. Also, the rotor on the clone 4401 can be slightly audible in a dead-silent room, which is standard for this integrated chronograph architecture and identical to the genuine’s sound profile.
