Matching blue wedding band is awesome

[@Ybalrid]

Interesting. Not sure this is a "filling" system. It's a "sealing" system on an eye dropper pen 🙂

[@ccahua]

Glad Goulet is giving the Nexus some love with this deeper dive; one of the first retailers to do so. My Blue medium is indeed a great EDC daily writer 2 weeks on the same ink. Good warning on the heavy weight, had to adjust writing style on long sessions to let the pen write on momentum vs steady normal grip which will tire. Nexus is a tank, dropped my cap on the hardwood floor 🥲but no marring or damage 😅 The shut off mechanism really makes this a unique pen worthy of Diplomat's century anniversary.

[@nancymilawski1048]

Was the floor damaged. I drop things all the time and it's because most modern items are too slippery (example cell phones)😀😀

If you buy a pen from any of the brands under the Yafa Brands distributor (Diplomat, Conklin, Monteverde, Maiora, Nettuno, Stipula, Yookers...) then you get a free bottle of Private Reserve ink.

[@TMT98]

Actually we might have seen something like that before.... 20 years ago or so when I was still in school I had this pelikan or diplomat fountain pen with a super weird filling mechanism. But even back then the seller told me, that this was the last one he had and that they were not produced anymore. It was an eyedropper, which also had a inner sealing and you had to twist some part for it to release ink from the big tank into the actual writing tank. And for filling, it used a super weird special ink bottle, which had something like a needle at the top, which you had to put into the back of the pen. It really was the craziest filling mechanism I have ever seen. Really a pitty, that back then I was a stupid brat, that couldn't acknowledge the beauty of it and didn't treat the pen well.... Now it's gone 😭

[@Skraeling1000]

It looks like a nice pen, with a well thought out anti-spill method, but that plastic eye-dropper needs to go, lol! An old style glass one with a rubber bulb would be an improvement. Also, the idea of having a place you can sit the barrel in while filling is handy, but it seems too big, the barrel wobbles around in it. To me, the whole ink bottle/pen stand thing seems like an afterthought - I wonder if it was rushed to market for the Christmas sales?

[@jamiedanielus]

Why must you keep making me spend money? I love this pen, it's now on my wish list for 2023. Love the channel and the support you give your community.

[@TheEverfever]

An eyedrpoper pen, but some of the sections in contact with the ink seem to be metal. Wouldn't that cause an issue? Or am I seeing wrong?

[@brandonb417]

Plunger cutoff is cool. But, you fill the pen in Nashville and fly to Denver. Open the lid and the pressure difference sprays ink all over through the nib. I hope there is a solution to this.

[@chhppx]

I think its best described as an automated Japanese style eyedropper

[@senzen2692]

Questions for a long term update: reliability (drying out, even if it seems unlikely, consistent ink colours), any burping.

[@alexandrel3804]

Is this useful in case your hand makes the air inside the barrel hotter? It seems it’s only useful for burping when traveling

[@EPeltzer]

I have eyedroppers and the burping is most a problem when you uncap the pen and write with it. I believe it's mostly a problem because your hand is warming up the pen body while you write and this transfers to the air in the chamber. And yes it's definitely worse when the ink gets low and there's a lot of air in the chamber. I'm sure traveling could make this happen as well due to air pressure changes. So the mechanism here would prevent the burping into the cap but I don't see how it would prevent burping when it's uncapped and you're writing with it. Having used one for a long time I feel eyedroppers are just not worth it because when the ink gets about halfway down you feel that you really need to fill it up to prevent the burping. So you really can't use all that huge ink capacity anyway. A good eye dropper design would just have a very large cartridge that you would have to fill with an eyedropper but the cartridge would be insulated and double walled off from the pen body. Or maybe the cartridge would be plunger filled but the plunger rod would be detachable and that way the capacity would be much larger.

[@Ag3nt0range]

I've got a question, if you've got time. Let's say you cap this pen at sea level, then fly to Denver. Is there a best way to relieve the pressure inside the ink chamber prior to un-capping the pen? It seems like you'd uncap the pen, and the pressure inside the chamber would force a lot of ink out rather quickly -- am I wrong about that?

[@TheOkazakiGuy]

Interesting new system. But I wonder how well it works to prevent burping while writing. Since the ink chamber isn't sealed when writing, air warmed by your hand from holding it could still cause it to burp, no? Anyway, interesting new idea. I like seeing some innovation and new ideas in this market.

[@jamesaritchie1]

As near as I can tell, it does absolutely nothing to prevent burping when writing. As I said above, this is just a complicated way of do exactly the same thing the Opus 88 pens do very simply.

[@debhan]

​@@jamesaritchie1 One benefit over Opus 88 though, is precisely this - you have access to entire ink capacity while writing, without manually opening the shutoff valve. (That said, there is not much to that and I love my Opus 88 pens!)

[@RubensMateusPadovezeArquimago]

legal, difernete e segura

[@welchianachi7707]

The best filling mechanism would be Sheaffer's Snorkel mixed with piston filler instead of sack. I have converted my two vintage Sheaffer Snorkel pens into piston filler, you operate them like old good piston filled pens by turning knob on the back. And for those concerned about spillage and drying, old Pelikan m30/p30 m60/p60 etc. they have seal on the cup so good that even after many months of being not in use they start writing upon touch.

[@pieromattirolo5430]

have you also retained a working snorkel along with the piston filling? This would be the best of two worlds. I once had a Sheaffer PFM. It's only drawback was limited ink capacity.

[@welchianachi7707]

@@pieromattirolo5430 Unfortunately that task was beyond my limits, but Snorkel tube is still present as it is in fact part of the feed so you can not get rid of them. Nevertheless even having not retractable Snorkel gives benefits, you only need to submerge nib 1/2-to-3/4 in the bottle of ink to be able to suck ink. Ammount of ink maby is not so great because i use Parker piston cartridge(twist type) but for my daily tasks it is sufficient.

[@joanwerthman4116]

Just wondering if they do anything to the metal to keep it from corroding from being in direct contact with the ink. Or is aluminum exempt from having a problem with this?

[@jamesaritchie1]

No, aluminum is not exempt. It may well be the very worst metal out there for corrosion from ink. There is a lining, but I don't know what it's made from. Probably plastic/resin.

How long did the ink take to fill the feeder to the nib? I just got one of these with the demonstrator model and filled it over 8 hours ago on July 6, 2024 and still no ink. Upside down, on its side, opened it up to let air get in and filled it a little more. Uncapped as well when it is on the side. Please tell me how to get the ink through to the nib. You never tell us the “average” time that it takes to ink the nib in any video. Please tell me. Or what am I doing wrong? 🎉

[@jamesaritchie1]

Isn't this just a very complicated way of doing exactly what the Opus 88 pens do very simply?

[@LoopedFeedback]

Even detrementially so, I think: with the Opus 88s, you can move the piston by fully unscrewing the blind cap to facilitate filling the pen. No such ability with the Nexus. It would have been truly innovative to have the Nexus "piston" simply be the piston face for sealing and putting a one-way valve in the piston face that one could push the pipette through to fill that way. And at north of 300 dollars, you could get three Opus 88 pens for the same amount, all of them having similar JoWo nibs. Or a Pilot Custom 823 with a beloved gold nib.

[@martinlebl631]

Except it is automatic, no need to remember to unscrew the release. But otherwise yes.

[@_TheTaoJones_]

I think for $100-150 this pen would make sense but when you start getting past Lamy 2000 and Pilot Custom 823 territory it’s a bit of a hard sell considering those pens still have plenty of ink capacity plus gold nibs, with incredible build quality and a lot of respect from the community. I feel like at this price the Diplomat is more of a novelty purchase for someone that has a collection already and money to burn.

[@def1ghi]

What is the feed on this pen like? I've never owned a Diplomat. Is it just a plastic feed? Seems like that would be key to get the thing writing fast after uncapping....

[@cpcfreak]

Is the fancy packaging / stand supplied because the new filling mechanism might make the pen a greater chance to leak if laid down on a desk? From the design, I suspect you want to hold it upright when you uncap, especially if you have changed altitude.

[@randy-9842]

Justin H: Imagine opening it up after your airplane flight has reached altitude ... or ... at an important office meeting after leaving it in the car on a summer's day. My thoughts exactly!

[@cpcfreak]

@@randy-9842 Yep. Normal eyedropper fills you can avoid the burp by equalising the pressure build up from expanding air, storing it upright in your pocket so air is at the top of the chamber the pen will naturally equalise pressure. But any of these pens with sealed chambers chambers are like pressure vessels, until you crack the cap, at which time after a rise in altitude the pressure will equalise any way it can. If you crack the cap with the pen sideways or pointing down after an altitude gain it's going to be an issue.

I personally prefer pens with innovative filling mechanisms and in this agree with Brian.

It's a nice looking pen but the sealing mechanism seems a bit gimmicky and over-designed to me. A simple system, such as the one in Opus 88 pens, is more appealing to me. The price is definitely a deal breaker. Even approaching two hundred bucks for a pen with a common, inexpensive steel nib seems outrageous. Such pricing has kept me from purchasing a great many other pens and it certainly guarantees I will not be considering a Diplomat Nexus. The shape of the ink bottle is familiar. Diplomat sources nibs from Jowo. Does Pelikan manufacture the inks?

[@martinlebl631]

Many people with an Opus or a vac filler keep forgetting to unscrew the release, so this is pen for them as the plug disconnect is automatic on uncapping.
