This seems like a fun concept, though with arbitrary exposure it's tough to gauge relative brightness. Photo taken within a few minutes of watches being in sunlight; taking another shot in a couple of hours might make for an interesting comparison as well. From left to right: Seamaster Pro (2019), Speedmaster Pro (2018), Seiko SKZ327 'Stargate', Lum-Tec B7 While the Speedmaster is a legible watch, after dark the Seamaster outclasses it by a mile - this is even more obvious on the wrist than it is in that photo. The Seiko punches way above its price class - it costs an order of magnitude less than either of the Omegas and shines brighter than either. The Lum-Tec isn't as bright as some of the others, but its markings are so clear that it's the easiest to precisely read in the dark.
