Non-ferrous alloys were selected for the shafts, as well as for the balance wheel. The pallet fork and escape wheel are made of silicon and are meticulously matched to one another. The average is usually 70 percent.Īt the other end of the power line, we find a completely new escapement. In total, the movement uses 85 percent of the power provided by the barrels. The efficiency of the transmission of energy is also increased thanks to the new gear design. The system provides an efficient management of energy since the torque is low and thus the pressure on the gear train is reduced, which limits wear.

The two barrels are arranged in series and are unmistakable, as they take up almost half of the movement. To achieve this level of performance, two large barrels are needed with long mainsprings. The amplitudes fall from an average of 300 degrees when fully wound to 240 degrees on the fifth day. The rate remains remarkably stable throughout. The automatic winding mechanism provides two barrels with power, which can keep the movement running for five days when fully wound. Power for 120 hours comes from two large sequential barrels. It is less complex than a bidirectional winding mechanism but is still efficient and, thanks to the friction bearing, especially resistant to wear. The winding system in Caliber 400 is unidirectional. Engineers discovered that problems occurred with the unidirectional winding mechanism relating to the ball bearing, which allows the oscillating weight to rotate freely. Oris has eliminated the ball bearing and replaced it with a smoothly running friction bearing, in which a steel shaft runs through an oiled bushing. The eye remains on the center of the movement and on the unique bearing of the automatic rotor. Matte-finish bridges and a single fine finish on the skeletonized rotor give Caliber 400 a technically robust impression that is perfectly suited to the brand. It was created as a response to modern needs: offering the best possible quality at a reasonable price to give the customer real value and also to underscore the concept of sustainability, which Oris has pursued for years with numerous models and initiatives - ambitious goals within the Oris brand philosophy.Īfter a five-year development period, a movement was created that is based on a solid foundation that can be seen at first glance through the large, transparent caseback. The goal was to design a highly efficient and robust movement, according to Beat Fischli, COO of Oris, who developed the new caliber with his team. This automatic movement was redesigned from the bottom up and every detail was put to the test. Oris developed the Caliber 400 movement in-house and tailored it exactly to match the character of Oris timepieces and the demands of its customers. The Swiss brand chose the Aquis for the premiere of its new in-house base caliber. Because it’s important to Oris to offer good watches at affordable prices, Caliber 400 will not replace existing standard movements, but complement them, and it won’t drive up the prices of the models equipped with it. In addition to the in-house hand-wound caliber series 110 to 115, new in-house automatic Caliber 400 will join the series movements from major suppliers like Sellita.

With its unique architecture - which does not include any of the “High-Mech” trademarks (like the red segment on the winding rotor) for which the Oris movements are known – it is clearly something new. It’s clearly visible through the transparent threaded caseback. It’s a rather discreet way to show the innovation in the Aquis Date that Oris calls “revolutionary” - modern Calibre 400. On the lower portion of the dial, a second glance reveals the power-reserve indication of “5 DAYS,” just below the “30BAR/300M” pressure-resistance indication. This, along with the brightly glowing Super-LumiNova-coated hour markers and hands, is designed for safe diving.

The grooved ring ratchets in half-minute increments and has a dark blue, scratch-resistant ceramic inlay.

Surrounding it is the unidirectional rotating bezel that identifies the Aquis Date as a functional dive watch. Immediately apparent is the well-known gradient dial that gradually changes from bright blue in the center to almost black at the edge. It’s not immediately clear what awaits you inside. It debutted in the modern Aquis Date dive watch, a timepiece that represents the essence of the brand, which we revisit today in our latest visit to the WatchTime Archives in the story below from Fall 2021.Īt first glance it looks like a “perfectly normal” Oris Aquis Date. The movement, the Calibre 400, further runs five days and offers increased antimagnetic protection. After a development period of five years, Oris launched its new in-house movement with 10-year recommended service intervals and a 10-year warranty.
