Good quality, but produces skin irritation

First the positive:
The bracelet is decorated very stylish and simple.
It is men and also women alike.
The holes cover the majority of the common arm circumferences.
The quality is good, come after a lengthy gestation period
dark color discoloration due to through the leather.
The closure makes a robust impression,
bend is not possible without great force effort.

The drawback:
Here I can only speak of me,
I noticed, however, that after about 2 weeks gestation
dry on my arm and itchy places occurred.
After removing the bracelet they disappear within a week.
This behavior is reproducible.
I suspect that the metal of the buckle causing these skin irritation.
Whether Nickel is, I can not say the suspect would but close.
