Prometheus Design Werx - when limited is not limited??

So the SPD x MKII Paradive came out a while ago and iirc ALL SOLD OUT

Today I get an email alert from PDW that reads:

Subject: Restock SPD X MKII Paradive • New SPD X Deneen Rancher Mug

includes image




I'm here wondering, How is a "Re-Stock" on a Limited Edition even possible???

Straight from the website...

SPD X MKII Paradive
The SPD Edition MKII Paradive is a special, exclusive collaboration in partnership with the American watch brand MKII Watches. Featuring our SPD Kraken Trident mark on the dial, orange tipped sweep and a PDW logo on the case back. This exclusive collaboration includes 2 PDW Ti-NATO Straps and an Expedition Watch Band Compass Kit.
Limited to only 45 pcs, SN 6 through 50.

What gives?

I checked my ORIGINAL summer release SPD and it has a number "3# / 100" ... not giving my exact number.

But how the hell is someone getting my serial in this release??

something is fishy or at least very confusing...
