Omega Seamaster 300 Professional

Had decided to get the Omega Seamaster 300 Professional. After years of feeling and touching watches at the various boutique stores...
Got offered Rolex Explorer 36, but don't like. Tested Grand Seiko SBGA229, but no more stock when i'm ready to get. Wanted Rolex Submariner 41mm No Date, but waited for 3 years, still no call, and price rising like hotcakes. Between Tudor Black Bay and Pelagos LHD, Pelagos LHD almost get me to put down the cash, but finally still Omega Seamaster 300 won my heart. But i am comparing the bigger one 43.5mm one and the two tone yellow gold. Still feel that the yellow gold will tarnish after many years of wearing, so skipped this.
