I am looking to buy my first Alpina. Looking for a sports watch that is not afraid of water. Don't need a true diver just one that can handle the pool without any issue. I do like the look of Alpina extreme diver, extreme avalanche, seastrong but these vary in price so wasn't sure if it was a difference just in look, features or movements driving the cost difference. Wasn't sure if there were movements the experts recommend. Kind of like if you are going Alpina look at watches with this movement in the sports category.
Any recommended buying sites? Feel free to PM me, even if it is for a private sale. The grey market has such huge discounts how can I not try one out?
