Some pros: Very accurate, the best mechanics with their + -4 seconds a day are resting. Quartz top. +- 4sec per month. Battery for 10 years, reliable, waterproof, not the first ones, so I know, I lost the past, I took the same ones, because they never let me down. Bathed in the sea with them, not a hint of fogging. In short, chic, brilliance, beauty. Cons below: Did not reveal, except as constantly twitching hair with a bracelet. But this is already a problem with most steel bracelets.
