Gravitas Sentry Aluminium Black

Meet the upgraded Sentry fountain pen, the larger sibling of Gravitas entry-level model. Though slightly heavier and bigger than its counterpart, the Sentry remains comfortable and user-friendly, thanks to its well-balanced, weighted section. With triple-start cap ACME threads, the cap smoothly disengages with just 2.25 turns and now features a Delrin sleeve for posting with no marks left on the barrel.

Machined from a solid rod of Aluminium – the new Sentry is featuring a finish not used till now by Gravitas the Anodised – Bead Blasting, a unique texture that further refines the experience of using one of these writing instruments. Different from previous versions – the Sentry features two o-rings : – a black one that ensures the link in between the section and barrel is solid – a red one that ensures the cap’s airtightness and prevents the cap from coming off when its not needed. 

The Sentry is equipped with a size 6 steel nib, compatible* with Jowo No. 6 threads, and an ABS plastic feeder, offering a range of nib options. Each Sentry fountain pen comes with a standard international 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.
