1.43-inch AMOLED, 466×466 resolution, sapphire crystal. Bright, sharp, with always-on support — the RTOS efficiency chip keeps the AOD battery cost low.
Suunto Race
1.43-inch AMOLED, 466×466 resolution, 1,000 nits brightness. Sapphire crystal (titanium model). Beautiful screen — but the always-on wake transition is the slowest DC Rainmaker has measured.
