Platinum 3776 Century Chartres Blue GT Fountain Pen
The Platinum 3776 Century Chartres Blue GT is a fountain pen that captures the elegance and serenity of Gothic art. Its translucent deep blue resin body is inspired by the luminous stained glass windows of Chartres Cathedral in France—widely regarded as some of the most beautiful in the world. The unique shade evokes both depth and clarity, as if each word written were touched by colored light.
Chartres Cathedral is a UNESCO World Heritage Site designated in 1979. The stained glass windows, dating from the 11th to the 13th centuries, are world-renowned for their brilliance. The deep colors of the glass—especially the remarkable blue—are considered nearly impossible to reproduce with modern techniques. While technological advances have produced brighter tones, the depth and richness of the so-called “Chartres Blue” remain unmatched, earning it recognition as a color in its own right. This pen pays homage to that legendary hue, translating its visual and emotional intensity into a writing instrument.
The gold-plated trim provides a warm, elegant contrast to the deep blue resin, enhancing the timeless character of the pen. Ideal for those who appreciate refined beauty and Japanese precision, it unites historical inspiration with modern craftsmanship.
Design and concept
The 3776 Century series by Platinum represents the pinnacle of writing design. Named after Mount Fuji’s elevation (3,776 meters), it symbolizes the brand’s pursuit of perfection. In the Chartres Blue edition, this classic form is elevated by a color that embodies light, history, and contemplation.
Functionality and filling system
Equipped with Platinum’s patented Slip & Seal mechanism, the cap prevents ink from drying out even after a year of non-use. This ensures a consistent ink flow and a smooth start every time. The pen uses Platinum cartridges or the included converter for bottled ink.
Package contents
The pen includes a Platinum converter, a blue-black ink cartridge, and a complimentary ink bottle from Inktraveler. It is presented in a standard gift box—ideal for both personal use and gifting. (Images are for reference only; actual product may vary slightly.)

Brand heritage
Founded in 1919, Platinum Pen Co. is one of Japan’s most esteemed fountain pen manufacturers. Known for combining craftsmanship and technological innovation, Platinum created the 3776 series to set a new standard in writing excellence.
The original 3776 was designed in 1978 by the late writing expert Haruo Umeda—nicknamed “Mr. Fountain Pen”—in collaboration with Platinum’s in-house design team. It quickly became a success, selling over 150,000 units within its first six months and earning lasting admiration.
Between 2009 and 2011, the series underwent a complete technical renewal based on over 40,000 writing data samples collected by Platinum’s subsidiary Nakaya. This research led to the development of the “Motosu” and “Century” models, featuring new materials, re-engineered nibs and feed systems, and a philosophy focused on functional and aesthetic perfection.
"Like light through stained glass, every stroke leaves a trace of luminous clarity."
