AI-assisted summary

Description from the seller

A0000003792

The Montblanc 644 fountain pen we present is in a very attractive condition, showing an elegant and well-maintained presence that reflects careful use over time.

The body and the section, made of high-quality black resin, retain a deep and uniform shine. Very light micro-scratches typical of a vintage piece can be seen only under close inspection, but overall the material is very well preserved, with no cracks or deformations and a clean overall aesthetic.

The gold-plated metal cap presents a natural patina that is very characteristic and gives the piece a pleasant vintage character. The surface shows uniform and elegant wear, with soft marks from the passage of time that do not affect the cap’s structural integrity. The clip retains its correct shape and functionality, maintaining good fit and alignment.

At the very top of the cap the Montblanc emblem is clearly visible, well defined and properly seated. The engraving of the model number “644” on the culasse remains visible, contributing to the correct identification of this reference within the brand’s classic series.

The original Montblanc 14-carat gold (14C) nib is in very good condition, with sharp engravings and no structural deformations. The nib presents proper alignment and retains its proper form, showing normal signs of use compatible with the piece’s age.

The ebonite feed is clean and well preserved, maintaining its intact structure and ink feeding function.

The pen has been serviced and tested, delivered fully functional and ready for use, as is customary for pieces prepared by Collecting Legacy.

Overall, this is a Montblanc 644 with a very attractive vintage aesthetic, where the metal cap patina adds character without compromising the piece’s good overall condition.

Conservation recommendations

To preserve this fountain pen in optimal condition, it is recommended to use quality inks specific for fountain pens, avoiding pigmented inks or inks with particles. If not used for an extended period, it should be cleaned with warm water, dried completely before storage, and kept in a dry place, away from direct light and extreme temperatures. The mechanism should be operated gently to ensure proper longevity.

It will be shipped in a courtesy box for proper conservation.

Happy bidding!}
