Other “high beat” movements such as the Zenith El Primero operate at 5Hz (36,000 bph). What does a faster movement do? Well it makes the watch more accurate because small deviations in the rate of each beat mean less as there are more of them. Of course this isn’t going to offer quartz level accuracy (as those movements operate at close to 33,000 Hz), but it is a really big deal for a mechanical movement, and the technology required to make it work is impressive.Then my thoughts went back to Greenwich, and seeing Harrison’s H4 marine chronometer. I realized I could put the physics unit inside a pocket watch smaller than the H4,fake omega speedmaster watches and following his tradition, it would be the most accurate chronometer in the world. In our case, 1.5 seconds per 1000 years. The temptation to make the most accurate chronometer in existence was, of course, irresistible. The vision crystallized in a fraction of a second and I shouted out an expletive in excitement. Then I remembered I was in a restaurant, and now everybody was staring at me.
In fact that is exactly what they have done. We recently reported on Carl F. Bucherer’s first tourbillon with a hands-on look at the new Manero Tourbillon here. Now for a diver with the Patravi ScubaTec.The small balance wheels in the 7727 beat at a wild rate when you look at them through the back of the watch. There are two of them and they average each other out. Of course the hairsprings are in silicon, as is the anchor. Without silicon, this speed would not be possible. Breguet is among the few high-end Swiss watch brands that stood firmly behind silicon when it was first being tested over a decade ago. Not all,omega speedmaster replica but a fair amount of Breguet movements use silicon parts to increase the performance of their movements. Though operating at a 10Hz speed is something altogether different. Breguet introduced their first 10Hz watch in the Type XXII 3880ST Chronograph watch (hands-on). 10Hz movements are capable of measuring up to 1/20th of a second. Though that isn’t really part of the 7727 as it isn’t a chronograph.The No.10 consumes 40mA on full steam, which could mean a daily overnight charge, plus exhaustion of the physics unit if a multi-decade life is required. So there is an Atomic Disciplined Crystal Oscillator mode that, for long journeys without charge, which allows the atomics to sleep most of the time and then wake up, work out how much the crystal has drifted, and then correct for it.
