The movement inside This reference is built with either calibre. The choice changes the price, the rate and the reserve — nothing else about the watch.
| Base | Seiko NH35 or Miyota 8215, automatic | Swiss clone of the maison's own calibre |
|---|---|---|
| Rate | ±15 to 25 seconds a day | ±5 to 10 seconds a day |
| Reserve | About 40 hours | 55 to 70 hours |
| Balance | 21,600 A/h · six beats a second | 28,800 A/h · eight beats a second |
| Servicing | Any watchmaker can service it; parts are everywhere | Serviced by a specialist; finished as the original is |
| Suited to | Wearing daily, keeping simply, spending less | Matching the reference exactly, and glass casebacks |
The Swiss movement is $50 more. That figure buys the rate, the reserve and a movement that reads correctly through a glass back — not a different watch.
Which we would take. If it is to be worn every day and serviced down the road from you, the Japanese is the honest answer. If it has to survive a loupe against the reference — or the caseback is glass and the movement is meant to be seen — take the Swiss.
The exact base calibre for this reference is confirmed in writing, with the QC film, before anything is dispatched. The two movements, explained

Description
PPFactory's newest "Steel King," the Patek Philippe Ref. 5726/1A Nautilus Collection Annual Calendar watch, has officially taken the throne! Featuring the signature Nautilus collection design with its rotating case window, PPF's craftsmanship, identical to the genuine article, employs forged and polished finishes, creating a striking contrast and perfectly replicating every detail of the original. The dial is a deep blue hue adorned with horizontal embossed patterns that radiate outwards from the center. The day, month, and date windows are clearly visible in black on a white background, and the 24-hour display with its elegant moon phase adds a touch of sophistication. Overall, it exudes a unique and elegant feel, making it one of the most beautiful Nautilus watches. The sapphire crystal case back houses PPF's exclusive 324S QA LU 24H/303 automatic integrated movement mechanism. The 21K gold rotor ensures efficient winding, and the fish-scale pattern beneath the Geneva stripes on the ruby bearings is exquisitely detailed. The movement finishing remains an industry benchmark. As PPF's first annual calendar watch, it accurately distinguishes between months with long and short dates, requiring only one date adjustment on March 1st each year. PPF welcomes your purchase; let's hold hands and journey through life together!
