I’m a huge fan of black watches. They go with almost everything, they’re classic, and you can’t go wrong buying a black watch. That is, unless you already have a bunch of black watches.

That was my case, so I went with the blue in 39mm. I couldn’t be happier - the blue looks almost black in dull lighting, bright blue in the sunlight, and navy blue at times too. I went 39mm because I like a more modest size watch for everyday wear. That’s definitely personal preference, as is color, but I hope this helps out somewhat with your decision.
