The M805 Ocean Swirl is a stunning yet controversial 2017 Special Edition from Pelikan.
While my initial view was ambivalent, in actual use, the pen has moved into the same vaunted category as the understated, equally variable, City Series San Francisco. I was fortunate enough to see seven copies among the local DC/MD stores and two additional copies from Pen friends; 9 in total. Particular thanks goes to Pen Boutique for helping me land mine.
Pattern and Color Distribution: Some posts seem to hint that some pen copies may have "nearly" 100% blue-green and others verging on total black. Not what I saw and may be due to range in perception. All 9 copies had clear bands of fluorescent blue-green swirls alternating with darker bands of shimmering deep blue-black occurring in approximate quarters as a constant. None of them were nearly one color, and certainly not pitch black (see a true black pen comparison side-by-side below). Granted, as a matter of degree, two copies leaned toward the darker side a tad more, but most were ~50/50 distribution, or close.
The fluorescent bands are striking when light hits them and depending on the warmth there is a bit of green peaking through, but to me its a blue-leaning teal or brilliant turquoise in most instances (Yama Dori calls!).
Pattern Alignment: Much has been made of the alignment or the lack there of between the fluorescent and darker bands in some copies. This is true. Not all the pens had aligned-patterns, but most seemed to have at least one vibrant band that aligned upon choosing the right cap-thread. I am sure there are some cap/body combos out there that do not align at all, along any thread. If this is important, seeing pens in person, or getting pics may help, but unaligned patterns look quite nice to my eye when in actual use. My copy does align, but when misaligned purposefully, the darker cap still looks elegant to me (pic below). YMMV.
Work-appropriateness: almost black, but not quite
My Ocean swirl saw more use simply because it was not a pen that immediately attracted attention, but still had a subdued elegance about it. In conservative settings, pulling out even a marginally showy pen, may go without comment but not without notice. This pen is work appropriate. In comparison, the Burnt Orange frequently invites comment (lovely nonetheless).
Dr Jekyll and Mr Hyde
Here's the Ocean Swirl next to the somewhat showy Burnt Orange
I chose a Fine nib. Luckily, it turned out to be a true fine, not "Pelikan- Fine".
My take on it: The color pattern is truly beautiful and unique. The pattern alignment issue can't be helped unless there is a way to nail down each body to a specific cap all the way through the supply chain and retail counters: fairly a tall order once it leaves the Pelikan factory given the number of hands that may handle them. Also when misaligned, the black cap contrast actually looks ok to me in actual use, YMMV. There are scores of pens out there that cover the whole pen with a single mosaic pattern from countless manufacturers including Pelikan (M620 Chicago anyone?). What's novel in that? This is more of a brave choice from Pelikan that is fairly subtle and renders a different look from one lighted room to another. Yet I doubt they will ever try this again. Cheers!
