i saw D'Andy selling one of this watch in the preowned section. Based on the wording, the 1000f = 300m is with the longer f and smaller gap between the =300m, hence i guess it should be the 16610 version, but strangely the clasp is not the usually 16610 but is the same of the 116610 version. i am confused now.
Saw that you were referring to my SubDate advert. If you looked at the advert pics, you could clearly see from the warranty card that it was a 116610LN, hence this referred to the current generation of SubDate. With regards to the dials, the 116610LN do have dials with both the descriptions in your post above; so it just depend on which was the one that came with the watch you purchased. Mine was from 2016 so it was clearly a 116610LN, with the newer 5 years warranty. If your research stood that the dial on mine was that from the 16610LN, you could probably think of it as that you were getting a more classic 16610LN dial cased in the newer maxi dial and lugs 116610LN, with the superior bracelet. The best of both worlds, if you will.
Likewise, I have last year flipped a 116613LB with the <space>m. Thereafter, I found myself wanting to have the same watch in my collection, so I bought another new piece. This piece had the <no space>m. Pretty sure that there was no blue dial for the 16610LN so this just shows that both dials were available for the watch, so don't fret it, mate.
