I love the look of these ringke bezels. I'm debating on the stainless with black numbers or the aluminum (also black numbers, but little more bold and says, "tachymeter" on the dial).
I'm curious if the aluminum version matches the metal case as well as the stainless. Hard to tell from pics online. Both materials seem to match about the same, even though the case is supposed to be stainless steel from what I've heard.
I have the GW-06-22 aluminium Ringke bezel and although not steel, it matches perfectly. Sometimes the bezel will catch the light more than the watch case, for example if there is overhead light (as the bezel is closer to the light source and the case further away and curved downwards). You will then perceive that the bezel is more shiny, but this isn't a negative, it actually looks superb and it's not a tacky shiny, it's subtle. If you angle your wrist so that the case and the bezel catch the light at the same time, you will see they are identical in colour, shade and to the eye, they seem made of the same metal.
And that's going into a lot of detail. Long story short, yes they match, they are the same colour and compliment and match each other perfectly.
I can't vouch for the ones with black numbers and 'tachymeter' engravings, but if they are like my 02 model, you certainly won't be disappointed. Hope this helps.
