Opinions are divided between machine-builders and Swiss watch movements , where most of them are still hand-made by master watchmakers. But it is impossible not to admit that the renowned brand Bulova introduced in 2010 one of the biggest revolutions in the watch industry with the advent of Precisionist , a model that quickly became one of the biggest highlights of the brand. Patented by Bulova, Precisionist was considered the most accurate watch in the world because of its famous differential: while a watch with quartz crystal mechanism delays approximately 9 seconds per day, Bulova Precisionist delays 10 seconds per year.
Yes, the numbers are incredible, but the incredible thing is that the Precisionist is also produced with the quartz crystal mechanism!
But how is this possible?
In general, the watch’s quartz crystals have the shape of a tuning fork with two rods. For the creation of Precisionist , Bulova has created a quartz crystal with three rods, which already makes the watches work at high frequency , generating 262,144khz, just over 8 times the frequency of ordinary quartz watches!
In addition, there are other factors that impair the accuracy of watches, such as temperature and oscillation. Also in mind, Precisionist creators created a thermal compensation system to decrease the temperature effect and produced a second-hand, non-oscillating movement. They simply slide without hitting each other.
This combination of technologies made the Precisionist an extremely precise wristwatch, taking the stand of brands like Rolex Submariner and Grand Seiko 36,000, models that until then also very high in precision.
