Nahvalur Eclipse Retractable Fountain Pen Review

Nahvalur Eclipse Retractable Fountain Pen Review

I love modern takes on classic fountain pen design challenges. Whether it is creating a better filling mechanism, modifying nibs to meet the needs of today's user, or trying make a better retractable fountain pen, I’m here for all of it.

Nahvalur decided to take on the latter challenge with the Eclipse, their version of a retractable fountain pen. We have seen several companies attempt to match what the great Pilot Vanishing Point brought to the market decades ago, but none have been able to equal it. Given that the VP is untouchable, how does the Eclipse stand up to the rest of the retractable pen market? Pretty well.

Nahvalur Eclipse Retractable Fountain Pen

The main design element of the Eclipse that differentiates it is the nib deployment mechanism. Instead of a button knock on the end of the pen (Vanishing Point, Platinum Curidas,) or a twist (LAMY Dialog,) this pen is what I’m calling a barrel knock. To deploy or retract the nib, you grab both ends of the pen and push it towards the middle. You can see the gaps in the middle of the barrel that allow the alternating aluminum parts to slide together and engage the mechanism. At the end of the day it’s still a knock mechanism, but handled in a unique way.

Nahvalur Eclipse Retractable Fountain Pen Barrel

Given this design, how do you get inside the barrel to access the nib unit and fill the pen? The rear of the pen twists, and in turn, unthreads the pen in the middle interior. The pen then slides into two halves where you can access the nib unit and ink converter. The pen fills by putting the removed nib unit into an ink bottle and using the supplied converter to draw in ink. Reverse the assembly process, and start to write!

I never used the launch version of the Eclipse, but there were reports of difficulty re-assembling the barrel once undone. Whatever the issue was seems to have been resolved in the current models, because I’ve had no troubles taking the barrel apart and putting it back together repeatedly.

From a writing perspective, I like the nib a lot. This one is a Fine Steel model (also available in Medium,) and both the line width and ink flow have been great. As someone who likes fine lines, I couldn’t ask for much more.

Nahvalur Eclipse Retractable Fountain Pen Writing

The Ecplise has many of the standard retractable fountain pen downsides, such as a long and wide barrel, and a clip in the grip area. It’s on the limit size-wise for me (my retractable preference lies with the Vanishing Point’s partner, the skinner barrel Pilot Decimo,) but still very usable. The bigger challenge with the Eclipse is the edginess of the aluminum parts in the middle of the barrel.

Close-up of the raised edges on the barrel.

The questions here are two-fold: 1. can you pinch your fingers when engaging the mechanism, and 2. just how sharp are those aluminum parts? To answer the second part, they obviously aren’t sharp, but each strip of aluminum has a raised lip along the edges. Given the number of them, you can really feel them on the barrel. Not so much when writing, but they are there. For the first question, I haven’t pinched myself yet, and I’ve used both single-hand and two-handed deployment options. If I didn’t pay attention, I do wager that I could get caught out.

Nahvalur Eclipse Comparison

Retractable pen comparison, top to bottom: Platinum Curidas, Nahvalur Eclipse, Pilot Vanishing Point, Pilot Decimo.

At $99, I think the Nahvalur Eclipse is a great option, if you can deal with the considerations listed above. Those considerations are what makes retractable fountain pens a secondary or specialty pen for many users, as for some people they just don’t fit their hand. For others, it offers something different than the Platinum Curidas in the same price bracket, and is much cheaper to try than the Pilot Vanishing Point and Decimo, both of which use 14k nibs. Overall, Nahvalur has made something interesting with this pen, and I look forward to continuing to use it.
