schmooze 0 Posted June 27, 2011 I noticed a incredibly smooth movement on a watch while on holidays recently. When the salesperson informed me it was quartz I was floored. The Brand is Bulova and the range is precisionist. I have one on the way at the moment. I believe PWC have some AP's with this type of movement. http://youtu.be/zPZPsimxteA Share this post Link to post Share on other sites

trailboss99 997 Posted June 28, 2011 Different animal Foolish. What you are talking about is a synchronous MVT. It isn't actually a MVT at all, it's an electric motor that drives the hands. It relies on the frequency of the AC power supply to provide a count in the same way a quartz clock uses it's crystal today. The issue there is that if the frequency of the AC power is off at all so is the clock. They were used by power stations to check the frequency of their output and special clocks with a very accurate electricaly driven pendulum clock and a seconds only synchronous MVT were made for just this purpose by the likes of the Sychronome Company and others. What we have here is an actual clock MVT with sweeping seconds that has only been readily available in the last year or so. Col Share this post Link to post Share on other sites

I believe PWC have some AP's with this type of movement. http://youtu.be/zPZPsimxteA The Bulova Preciscisionist uses the Precisionist movement, it is a 16 beats per second movement. ULTRA smooth. Smoother than any mechanical movement. And no, Robert has nothing like that in his AP's. Those "smooth" sweep quartz chrono movements are usually 5 beats per second on the chrono hand only, the running seconds is still one beat per second.

It's a pity we can't obtain some of the higher end reps with a smooth sweeping quartz . Share this post Link to post Share on other sites

I have three chronographs that have the ISA 8172 quatz chronograph movement in them. That is one of the ISA movements that has the 5 beats per second faux sweep seconds hand. The normal person would never know that the chronograph was a quartz movement just by looking at the watch...as the chronograph second hand appears to be a sweep second hand...but the running seconds sub-dial is moving in the normal 1 beat per second.

Not very smooth, especially on a large hand. Share this post Link to post Share on other sites
