Thanks for the info. If it isn't too much trouble, would you mind taking a few pictures of the bracelet and clasp mechanism? Its hard to find good information or pictures about these watches, which is surprising because they have been around so long.
I just wish the A158/159's were a bit dressier. I have been interested in a Nixon Re-Run for a while, because it checks many of the boxes I have been looking for. Dressy, digital, simple. However the price is just way more than I am willing to pay for something like that.
