Dennis has steered you in the right direction to get the info you seek, but in the meantime, I will say that eBay seller
holbensfinewatches has had very positive feedback by members of another watch forum that I'm on. I myself have no personal experience of Holben, but he was very well regarded as a straight dealer by the guys there.
As to the particulars of the watches themselves, there are many on this forum more qualified than me to comment.
Good luck and welcome to the forum.
