Caran d’Ache Timegraph - Fountain Pen With Mechanical Movement

With the exception of a few clocks and other time-indicating objects, wristwatches are the only expression of watchmaking these days. But this has not always been the case. Naturally, there were pocket watches but also watches disguised in all types of objects: canes, miniature music instruments, pendants, keys, or even perfume-dispensing guns. Reviving this tradition, Switzerland’s well-known writing instruments company, Caran d’Ache, presents Timegraph, a fountain pen that tells time thanks to a miniature mechanical movement.

Thanks to this miniature movement, the Caran d’Ache Timegraph is well-proportioned and keeps an excellent balance for optimal writing comfort – it is 15mm in diameter, and 151mm long (with the cap). The body is PVD-finished while all metallic elements are palladium-coated. The hand-polished nib is fashioned out of 18k gold and is available in various sizes from EF to B. Three sapphire crystals allow you to discover the nib and both sides of the movement finished with Geneva stripes – just like a traditional movement from a wristwatch.

  1. Cool and unbelievably expensive gadget.
    Having said that, the time is hard to read due to the mechanism behind that. But I guess the watch face is customisable so that may not be an issue.
    The positioning of the crown should really be improved: as it is at risk of breaking and it will get caught in jacket pockets,etc. For the asking price I don’t believe this is a good enough design.
