If you're looking for a quality, inexpensive homage to the Submariner, this is it. Seiko is known for their great quality and the SKX031 doesn't let down. The only downside to this watch is the bracelet and it's cheaper folded links. Although, some people enjoy the stock bracelet. I purchased an aftermarket bracelet for my 031.
I was surprised to find this watch new, as Seiko discontinued it several years ago. Luckily, Mr. Watch is still selling it, but obviously you're paying a little extra premium for their ability to source this discontinued watch.
Mr. Watch shipped fast, and I was happy with that. But they placed my watch in the watchbox, without a proper mount. Then, they place the watch box in a cardboard shipping box, about 3x the size of the watchbox. This would have been all good if they had padded the watch box in the shipping box, but it was in there all alone! So, needless to say, when my package arrived, the watch had been bouncing around the cardboard box outside of it's original watch box. Oh well. It didn't have any damage. It could've all been avoided with a little bubble wrap or some newspaper.
