Smaller case or more coverage?

PACE Pro’s diameter adds 2.05mm on each side of a centered case outline. Compare the space beside each watch and where its band starts to curve around your wrist. PACE 3 offers the smaller outline; PACE Pro occupies more of the wrist.

Screen and bezel proportions

PACE Pro pairs its larger case with a 1.3-inch AMOLED display, while PACE 3 uses a 1.2-inch MIP display. Look at the screen, bezel and band together to choose the design you prefer.

Compare size, then color

Use one clear wrist photo for both black silicone configurations. Once you have a preferred size, try White on PACE 3 or Grey and Blue on PACE Pro. Keeping the source photo the same makes the differences easier to see.
