Introduction to Sinn: a Convergence of Watch*** and Engineering

If you look a bit closer, you'll see a clear motif in the finishes of the steel: flat su***ces have a brushed finish, and bevels are mirror polished. The bracelet follows this same pattern which makes it both interesting and understated. The font and printing on the bezel are also excellent and easy to read. Unlike most other bezels, every minute is marked, *** for easy and accurate timing — a very impressive and welcomed detail.There's a second motif of circular detail, as well: the yellow ring on the crown, the subtle reflective circles of metal around the hour markers, the circle of luminescent paint on the hour hand, the round covers on the lugs. The weight feels just right to counterbalance the mass of the watch.The movement is Kinetic quartz which means there's a rotor and generator inside the case.When you move your wrist, the rotor spins and a small voltage is generated that gets stored in a rechargeable battery. Unlike the new Seiko Velatura, you can't handwind the SKA367, but it's efficient enough to not be a drawback. The SKA367 uses the 5M62 movement which has a six-month power reserve, low battery warning, and a nifty button at the 2 o'clock position that temporarily re-purposes the second hand to show you the amount of charge currently in the battery. As with most quartz movements, it's accurate to ±15 seconds per month.As you can tell, I very much like this watch.
