Review: Staur Copernicus Open Heart Watch - This a very nice watch at this price point. Mine keeps very good time and the band is larger than most and that is a good thing for those of us with larger wrists.
Review: A nice quality watch for an affordable price. - It is a very handsome watch and does not look cheap. Just received it today. Came faster than expected and came in a nice cardboard box. Love that it is easy to read. A nice feature for older adults like me. Set up was simple. The watch band is nice. It does fit my small wrist,however, I wish it was a tad smaller. The other benefit is that I never have to buy a battery. I have other watches that cost me $20 each for a new battery that only last a year. The only other down size might be you do have to treat it with a little more care. Overall I am very happy with this watch and provided I take care of it, it should last for years.
