Gravitas - Sentry Aluminium Black

Meet the upgraded Sentry fountain pen, the larger sibling to the entry-level model from Gravitas. While slightly weightier (depending on the material) and bigger than its counterpart, the Sentry maintains a comfortable and user-friendly design, thanks to its weighted section. With triple-start cap ACME threads, the cap effortlessly disengages in just 2.25 turns. The cap now features an inner Delrin sleeve to acomodate a smooth posting motion without leaving marks on the barrel.

Machined from a solid rod of Aluminium, the new Sentry Aluminium is sporting the new 2025 Gravitas finish - Anodised Black with a bead blasting texture, equipped with double o-rings : one at the link in between the section and the body, to ensure a solid connection and prevent the section from untwisting - and one red o-ring at the link in between the cap and the body to ensure air tight seal and prevent the cap from coming off when the pen is carried. 

The 25mm-long section, ranging from 13.25mm to 11.5mm in width, is expertly crafted from 304 stainless steel. Coated in sleek black PVD and adorned with micro-machined grooves, the section ensures a secure grip during every writing session. Equipped with a Gravitas-production size 6 steel nib compatible* with Jowo No. 6 for threads - abs plastic feeder, the Sentry is offered in versatile writing options: Extra Fine, Fine, Medium, Broad and Fine Flex.

*when swapping for a different non Gravitas 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.

Enhancing your experience, the Sentry comes with a standard international converter provided with each fountain pen.

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