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
IWC's Aquatimer collection has a history of nearly 50 years, and today the name Aquatimer has become synonymous with diving. This particular model features a simple and elegant design: a stainless steel case with a black rubber strap that can be easily removed by hand; a round dial with a date window at 3 o'clock; a large 15-minute diving bezel; and the "luminous" function highlighted in a striking yellow to ensure easy monitoring of oxygen levels even in deep water. The "luminous" functions are incredibly powerful, featuring six "luminous" markings and a Super-LumiNova* coating, ensuring you're the brightest star whether you're deep in the ocean or clubbing. The dial has a sandblasted finish, giving the dial lettering a three-dimensional look, and the luminous markers have a raised, glossy finish. The crown is a lock-type water resistance mechanism, providing 2000m water resistance. It has a 44mm case diameter, an anti-reflective sapphire crystal, and a Swiss-made Eta-SW300 movement. Complete packaging! Arrived in perfect condition.
