The original Royal Oak was originally supposed to be a luxury sports watch, but compared with sports, it paid more attention to luxury. In the offshore area, this problem was corrected by doubling the water resistance to 100 meters, adding some magnetic resistance and timing complications. The increased size makes the case more durable, and the internal AP movement 2126/2840 requires more space because it uses JLC-based 888 and adds a Dubois-Depraz chronograph module. Then consider that the movement is also wrapped in a soft iron inner cage to increase the magnetic resistance, and the dial must be unfolded to include the tachymeter scale on the outer flange. All these factors will significantly increase the size of the watch, so all these factors can easily justify the increase in the proportion. As far as I am concerned, the increase in quality is worth the increase in durability and functionality. I won’t feel comfortable using the standard Royal Oak for body surfing, but I do like its design. There is no need to hire babies at Royal Oak Offshore, I think this is one of the main added value.
