+ The pleasant leather strap is long enough and enough good for about 20cm circumference.
+ There are also here the housing ends slightly curved towards arm circumference: so that the clock is nestled up well 18cm wrist circumference perfectly ...
(-) ... Unfortunately she sits at my joint 20cm circumference at the side edges but already slightly on the radius and ulna on, rather than fully to conform. (A little bit of the effect that bothers -only so much more with just a large Gelenksumfang- the Sport model of Vibralite8. See my local review)
