For the writing sample, I filled this Bronze Corydoras Nautilus in medium point with Waterman Mysterious Blue. After taking a dip, I'd like to offer my first impressions of this new fountain pen design.
The thicker, weightier design feels substantial in hand. Even though you cannot post the cap on the back of this pen while writing, the Nautilus has a well-balanced weight. Combined with the large grip area and ebonite material, the Nautilus has a comfortable feel for an oversized pen.
The medium point on this stainless steel nib performs beautifully right out of the box. With previous Narwhal models, the nibs tended to write thicker than their size designations - the fine writes more like a medium and a medium more like broad. This medium writes like a European medium point with an average flow - not too dry and not too wet. I checked with Frank from Narwhal who confirmed that this new range of nibs conforms to European sizing conventions. So, if you're familiar with the line width of Jowo or Bock nibs, Narwhal nibs will be similar.
Material, Packaging, and Pricing
In contrast to the resin or acrylic construction of most modern pens, Narwhal builds the Nautilus out of solid ebonite - a material used in many vintage fountain pens. The difference is one that needs to be experienced firsthand to truly appreciate. It has a warmth that becomes more noticeable the longer you write with it. The downside is that the polished surface is a fingerprint magnet. Also, there is a characteristic smell - ebonite has a slight sulfur smell due to the vulcanization process that will fade over time. While it's not as bad as Noodler's resin pens, ebonite can be offensive to the olfactories after opening the box for the first time.
