The Waterman Edson Diamond Black is a legendary instrument that reigned as the brand's flagship for over two decades. Introduced in 1993, the first color in the collection (followed the 1993 Emerald Green and Ruby Red), it is named in honor of the company’s founder, Lewis Edson Waterman.

Architecture & Performance

• The "Buttery" Inlaid Nib: The soul of the Edson is its distinctive 18K solid gold inlaid nib. While it is famously stiff—often compared to writing with a high-precision nail—it is celebrated for being "smooth as glass" on paper.

• High-Altitude Engineering: Designed for the modern executive, the Edson features a sophisticated three-fissure ink feed system. Waterman famously guaranteed this system to be leak-proof up to 30,000 feet, preventing ink discharge caused by aircraft cabin pressure changes.

• Commanding Presence: This is a substantial, oversized pen designed for those who prefer weight and girth. It weighs approximately 47 grams (capped) and measures 15.2 cm in length, giving it a commanding feel in the hand that rivals other "grail" pens like the Montblanc 149.
