The Waterman Expert Mk.1 was first produced, in France, around the late 1980s.
The Expert Mk.1 differed from the later versions in that it was lighter in weight, an important consideration at the time, had a slightly different trim, and a much more attractive, sculpted, flat sided, two tone nib with a distinctive elongated breather hole. The cap incorporates a cluth whic engages the ring at the end of the barrel so that the cap lip doesn't make contact with the barrel when posted, preventing scrstching.
The pen has a good, solid feel and is very comfortable in use. t wrtes with a smooth, medum line.
The pen is finished in Burgundy with 23Ct. Gold filled trim. A cartridge/converter filler, the pen is supplied with the original ink converter fitted, Cartridges are readily available online but using the converter with bottled ink is probably a better option.
The Waterman Expert is still made today in a large range of finishes but, in terms of quality, the Mk'I pen is still the best of the bunch. It is also quite hard to come by.
