That's a very vivid blue and very few companies offer a blue in that tone. I recall, and may VERY well be wrong, but I think JLC may have offered a dive watch (since discontinued) that is a very bright blue.

The only other thing, without any context behind the photo shared, is that it's a TAG Heuer Aquaracer but their blue is not that bright. I think Badhobz is on the ball for Submariner or an Invicta.
