The clock for cool calculators - not with an adjustable strap.

The integrated calculator does the job. The buttons are easy to operate.

On the wrist, the clock also acts not as clunky as you would suspect, according to illustration. Overall, my husband is very satisfied.

But a major disadvantage. In my view, the clock for the online shipping not suitable because the strap can be adjusted only by a watchmaker on the corresponding arm size. It must in fact be removed from the bracelet individual members, which can be naturally pay extra watchmaking.
