I haven't worn my Bulova Precisionist for, probably, over a couple of years. It's been sat in a case, along with others of my collection, ticking gently away. Anyway, I thought I'd get it on the wrist today - what with the clocks going back an hour this weekend.
I took it out of the case and checked the time against the atomic clock - it was exactly, to the second, one hour fast. In other words, though not changed to compensate for changes in BST and back over two years or so, it had otherwise kept completely accurate time. The second hand is sweeping as smoothly as you would expect from a Precisionist.
I think that's pretty good, and also a tribute to the Bulova brand. This is one of a very few quartz watches that I own and, I have to say, it's a beauty.
