Due to the very simple change mechanism for the strap, it can be good individualize / combine. At the enclosed black silicone band I bought with even a yellow silicone and a black leather strap.
The optics I find great, function is also given. The clock is running very well since> 6 months.
I (black / silver with white dial and brown leather strap) bought me this watch type nor the JR1390 recently. With this I can use the two black bracelets also.
I can only recommend this clock (s), so full 5 stars subjective.
