New member here, but not new to watches. Have been buying, selling, trading watches for quite a few years now. I was recently able to pick up a grail of mine, a Polar Explorer II 16570. This specific watch is a Z series from 2008 with solid end links, and came with full kit. Deceptively light (probably due to the hollow bracelet links), and extremely comfortable. Loving the pure white dial (my first white dial watch too), and the contrasting red GMT hand.
