Maker: Waterman.
The Charleston was one of the first designs offered by Waterman after its acquisition by Newell Rubbermaid, and depending on one’s level of cynicism, it is either a reassurance that the new owners are attending to the company’s history or a trick to make people believe just that. Its lines are based on the original Lucite incarnation of the Hundred Year Pen, broadly speaking, with a mid-body band flanked by small longitudinal incisions. It is not a precise replica, but like the latter-day Parker Duofold it gives a good suggestion of how the older pen might have evolved if it had remained in production across decades.
Unlike the Hundred Year Pen, the Charleston has a relatively small point. It is, like the rest of Waterman’s modern production, a relatively stiff point, and its short tines have little spring in them. It is smooth enough, but rewards a light hand more than it does a heavy.
Production Run: 2001 to present
Cost When New: MSRP in 2016 is about $240. On the 2007 price list, it was $130, an increase which is not quite accounted for by inflation (try try this calculator if you’re curious).
Size: 13.9 cm long capped, 14.7 cm posted, 11.9 cm uncapped.
Point: 18K gold.
Body: Plastic.
Filler: Cartridge, capacity approx. 0.6 ml or 1.4 ml (international pattern), converter of 0.8 ml

In profile, the modernity of the clip is even more evident. The false blind cap is highly suggestive of a piston filler, which renders this pen a bit of a tease.
