Movement and Caliber Performance

The upgraded version of SBF Panerai 441 with integrated movement and power reserve window has arrived. Upgraded with P9001 integrated mechanism; not that little workshop mechanism assembled with Nanning 2813 parts a few years ago.

1. P9001 integrated mechanism has enjoyed a good reputation for years and its quality is stable. The Nanning 2813 mounting mechanism was already eliminated from the market once in 2019.

2. Watch enthusiasts at home and abroad compared and modified the P9001 integrated mechanism; The thickness is exactly the same as the original. The Nanning mounting mechanism is thinner than the original.

3. Real bearing is used in P9001 integrated mechanism and original mechanism; The bearing does not rotate together. The bearing in the Nanning assembly mechanism is a decorative, fake bearing;

Therefore, when the rotor rotates, the fake bearing rotates with it. This is the simplest method of discrimination; Be careful not to buy such small workshop mechanisms.

I hope this article will be useful to you. I will share more detailed disassembly, real shot review and real-replica comparison in the future.
