It's interesting that this clone movement has 28800 bph instead of 25200 bph like original Omega 8605 caliber. That means that power reserve will be not 60hr but much less. For me is 28800 bph much better and nicer in terms of smoother second hand so this is not a problem. Timegrapher show me about -5sec / day accuracy, in real life it's about -15sec / day so I will make some corrections on caliber after about 14 days.
Regarding clasp. It doesn't "click and lock" easily, and you need press it hardly to secure it. Links on bracelet aren't treated so nicely like on genuine bracelet, but it's acceptable. I'm looking for 21mm rubber strap too, but for now it's unavailable. Genuine SS bracelet cost too much.
In general I'm very happy with this watch and that we have new Omega player on the floor named VSF.
