Gravitas Fountain Pen - Sentry - Raw Grade 5 Titanium - Limited Edition (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. With triple-start cap ACME thread profile, the cap smoothly disengages with just 2.25 turns, the delrin sleeve of the cap protects the surface of the barrel when posting. 

The 25mm-long section, tapering from 13.25mm to 11.5mm, is expertly crafted from Stainless Steel and features finely machined circular grooves for an enhanced grip. The cap and barrel are machined from a single block of Grade 5 Titanium making for a lighter sentry pen with a smooth raw metal finish.

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 its 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.
