The AP Royal Oak replica has been a popular choice among watch enthusiasts, with the JF and ZF factories being the main competitors in producing this model. J12 was the first factory to create a replica of the AP Royal Oak 15400, and they have been manufacturing it for over five years. Over time, they have made several improvements, and the latest version, V5, showcases these enhancements. On the other hand, ZF entered the market for replica AP RO 15400 two years ago. Initially, their case finish and bracelet quality were not on par with J12, but ZF has since made significant improvements, and now both J12 and ZF offer similar quality for the AP Royal Oak 15400.
APS is not a newcomer in the watch manufacturing industry. Prior to creating the AP RO 15400, they successfully replicated the Royal Oak Perpetual Calendar 26574, which received positive feedback and attracted a significant number of buyers. In 2021, APS factory introduced the Audemars Piguet Royal Oak 15400 replica, with its standout feature being the movement. Regarded as the best clone 3120 available in the market, APS 15400 has garnered attention and is priced higher than its counterparts, J12 and ZF.
Due to the use of the in-house 3120 movement, the APS 15400 is considered to have the most accurate case profile. It has a diameter of 41mm, which is similar to the genuine watch. Additionally, the case thickness of the APS 15400 is 9.8mm, which is closer to the thickness of the authentic watch compared to the JF or ZF 15400, which have a case thickness of more than 10mm. APS also claims that the case construction and assembly method are the same as the original, allowing all case parts to be interchanged with the genuine watch. The most significant improvement is that the movement is no longer based on the Miyota 9015 with extra plates, making it no longer a “fake 3120” movement.
I have measured the case thickness of both the ZF 15400 and APS 15400 watches, and there is a subtle difference between them. The case thickness measures around 9.7mm or 9.8mm, which may not be noticeable unless you have both watches in hand. However, some people do pay attention to these details. It is quite challenging for a replica watch manufacturer to reduce the case thickness while maintaining the authentic construction of the original watch. In the case of the AP RO 15400, APS factory has successfully developed a clone 3120 movement and made improvements to achieve a perfect result.
The AP RO 15400 from APS factory is highly regarded for two main reasons. Firstly, it features the best clone 3120 movement, which closely resembles the authentic AP 3120 Calibre. This ensures a high level of accuracy and performance. Secondly, the watch has the correct case thickness and all case parts that can be used on a genuine AP 15400. This provides a sense of authenticity and quality.Regarding the stainless steel AP RO 15400, APS factory offers three models, each with a different dial color: black, blue, and white.
