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
[IWS Factory 2023 highly recommended highest version on the market] The new IWC Portofino Day & Night Automatic Watch 34MM presents the beauty of the changing of day and night with a highly poetic visual effect, and is equipped with gorgeous diamond setting to highlight its elegant and noble temperament.
1️⃣ With a diameter of 34mm, this case is especially suitable for women's slender wrists, making it lightweight, delicate, and exquisite to wear. The bezel is set with 54 brilliant-cut round diamonds, each measuring 1.7mm. The special prong setting maximizes the angle at which light enters the diamonds, resulting in a more dazzling and brilliant fire effect.
2⃣️ The dial features a sunburst pattern, giving it a softer luster. The slender hour markers and elegant leaf-shaped hands complement each other perfectly, with each hour marker set with a diamond, ensuring a delightful experience every time you check the time. The 6 o'clock day/night indicator on the dial is decorated with a gold moon and sun, rotating once every 24 hours. Notably, the sun during the day is surrounded by sunlight rays, while the moon at night is surrounded by a twinkling starry sky.
3⃣️ Equipped with a custom-designed automatic winding movement, beat rate 28800, and 50 hours of power reserve.
4⃣️ Paired with a soft and comfortable small calf leather strap + original buckle, multiple strap colors to choose from!
