So my main concerns at first were overall build quality, and whether or not the SW510 had been optimized or somehow altered to better accommodate manual winding vs the 7750/SW500, which I’ve read have been known to have problems when hand winding just like the 2824/SW200. So far, the case has been really great and it hides it’s thickness very well. The pushers are very crisp. The bezel was very hard to turn, but I’ll get to that in a minute. The tropic strap is actually quite thick and comfortable, and the buckle very high quality.
The manual winding action is quite nice, so that tells me that this probably isn’t just a 7750 clone with the rotor removed. It was quite hard when researching to find anything definitive about the SW510mbhb, in terms of what is different about the movement. Perhaps because it’s so new and only in a handful of watches at this point. Regardless, it is running +3 after four days, and I’m pretty sure it gained most of that after the first day. There isn’t much change I can discern during the last two days, but I don’t have a timegrapher(just going off of my atomic g shock).
So anyways, I was pretty thrilled with this piece, and decided to keep it. Then today, upon turning the very difficult bezel, and mind you this is bidirectional, so no ratcheting, the bezel literally popped off. It slides back on and stays firmly in place, but if you apply the smallest amount of upward pressure, it pops off. The only thing holding it in place is a gasket. Is this normal for a friction bezel(that’s what this is right?)
Anyway, wrote hodinkee an email, because it probably needs to go back. Really irritated because this has been the best timekeeper I’ve had outside quartz.
