Why do most of the watch ads display the time as 10:10?

Tweet

watch ads stick to roughly 10:10. Strangely, we also found plenty of digital watches set to the same time. This is obviously some kind of advertising standard. Why? Did some famous watch inventor die at 10 past 10? What's the significance? According to a reliable source, the reason is purely aesthetic. A watch reading 10:10 has a clean, symmetrical look. Also, the hands don't obscure the watchmaker insignia, which is usually located directly below 12 o'clock.
