Pióro wieczne Gravitas – Sentry Raw Grade 5 Titanium – Titanium TiSiNx – limitowana edycja (2025)

Meet the upgraded Sentry fountain pen, the larger sibling of Gravitas' entry-level model. Though slightly heavier than its counterpart, the Sentry remains comfortable and user-friendly, thanks to its well-balanced, weighted section. 

The 25mm-long section, tapering from 13.25mm to 11.5mm, is precisely machined from a solid bar of Grade 5 titanium the cap and the barrel gets to be complemented by a section machined form Stainless Steel for weight balance, all the parts feature a unique TiSiNx finish (titanium silicone nitride) - a tough and wear resistant finish it increases the surface hardness and reduces friction while offering an attractive blue finish while keeping the raw exposed metal feel.

The recent upgrade for the Sentry brought two o-rings, one on the section that maintains a tight seal, preventing the section from coming off when it's not needed, and one on the barrel that prevents the cap from accidentally coming off.

The Sentry is equipped with a Gravitas-produced size 6 steel nib, compatible* with Jowo No. 6 threads, and an ABS plastic feeder. It offers a range of nib options, including Extra Fine, Fine, Medium and Broad. Each Sentry pen comes provided with a standard international plug-in cartridge converter.

*when swapping for a different nib unit you are sole responsible for checking the fitment of the new nib - we are not responsible for any damages that may occur from the use of non gravitas nibs/nib units.

Elevate your writing journey with the exceptional craftsmanship of the Sentry fountain pen.
