The optics and processing of the clock is similar to three times more expensive by other manufacturers. The bracelet is made of good leather and perfectly finished (contrary to other review not too hard) and 2 cm longer than usual, so that it fits on stronger wrists. The absorption of the clock takes some time to complete, since that has a power reserve of 36 hours. After about 25 rotations of the resistance when pulling is greater, overspeeding is unlikely. My clock is a day at about 7 seconds, so I have to pull out the crown only for 7 seconds to make it. Everything together makes this clock to my favorite watch although I possess far more expensive hand-wound.
