The fully mechanical drive is a Swiss product and is known as durable and accurate, you can screw on the clock with a little talent and confidently adjust it with a small screwdriver / feintunen: Automatic watches are rarely adjusted optimally with your first order. This should be based on + - let one second aberration or less per day to adjust a value that is not exceeded by a Rolex or Patek Philippe.
The bracelet is solid, but stiff, I recommend to replace it with an opportunity against a band of Junker specialists ankhstrap.com before disengages the seam.
Overall, a very nice, classic acting and highly recommended quality watch for any occasion, from German production.
