the 4th gen bezel click mech is not like the gen (too loose and flimsy) the case shape is wrong, crown is wrong, bracelet is bad (needs a rubber strap- easy fix), and the logo on the dial is placed wrong and too big...... the ultimate needs a gen crown, and a correct logo on the dial and double AR but some gen owners "wash" off the outer AR anyways so this will pass. both are great but the ultimate sets a new standard! i really wish the chrono had correct subdial spacing which will never happen. what movement is in the gen? maybe if i can swap the movement and get a genuine dial..................
