These are not original. I have one and have reasearched on these. IF the strap is detachable, this is a 1st copy. If not, this is a C or maybe a D copy. And the copies break really easy. I've got one and it has become un wearable after maybe 6 months, it's a B copy. The bezel has lost it's color, shows the wrong time, etc etc. From the buckle alone, the poster's watch looks a D copy. So, please DO NOT call it an original. Another thing, A copies tend to last a little bit longer and are of better quality.
This is what an original looks like:
