Some feedback on the recent UI changes; it's now somewhat challenging to view/open multiple listings as you can't right click a tile listing in a new tab with view item button removed. Additionally, the link to the item page and sellers site is tucked away below the contact dealer and watch item options. Would you consider moving the item and dealer links to a more prominent position, or changing the properties of the tiles to allow opening in a new window?

The knot looks authentic and in good condition. Wouldn't pay much attention to anything AI says about this sort of thing.

There was supposed to be more in that reply, but Shodai Yasutsugu was a very much a Keicho era smith and Nanban Tetsu has a broad meaning not just limited to Dutch or Portugese trade.

It was a Mumei Gendai:

Agree with Nathaniel, uma-ha came to mind immediately. Compare to a Gendai I used to own:
