Is this genuine sub insert modern or vintage?

Hoping to get an expert opinion on this one. I couldn't really see it that well with the camera angle and I have no clue about this stuff-

It appears to be modern as a vintage insert would have an acrylic pearl if it was NOS...

I second that. My vintage gen 1680 insert clearly has the acrylic pearl and looks much different from that one.

It could be a tritium insert from a 16800...they are very expensive!

The shape of the 4 in the 40 indicates it is not modern, or at least not the newest version. It could be from a modern sub with lug holes. It could be a 16800. It could even be a Seadweller insert and not a sub insert.

Note the style of the 4 on my gen 16610 insert with lug holes:

Note the style of the 4 on the newer 16610 insert (don't be thrown off by the part number - this IS for a 16610):

Thanks for the feedback...I'm not going to lie, I bought it before I even posted that picture, but figured it might be prudent to actually know what I was going to be getting. That's my style with these parts... I like roll in "blind" on their purchase and then make a game of it for the community to figure out what we're looking at. That's how I'm rationalizing it today.

The finish being more glossy seeming than what I usually associate with vintages causes me to wonder if it's more recent. At the same time, I've got a very old insert off a genuine red 1680 that has that same type of finish even though it's faded.

I just checked the measurement, and this should be the ultimate clue:

37 1/2mm

31mm

I keep squinting my eyes to see if I can make out a metal ring around that pearl, but I can't seem to squint hard enough...
