It has been four years since I wrote a post The Visconti Rembrandt v The Pineider Avatar fountain pen (8 September 2018). At the time, I had owned the Rembrandt for less than a week. I think my comments then were fair and still hold good. As to which one of those two pens you prefer, that is subjective and each has its merits.
It has been my habit for decades, to write a daily entry in my diary. Currently I use an A5 page-a-day diary from Rymans. This year, it was my intention to use a different pen and ink combination each month. I started out with a Cleo Skribent Classic Gold in January but was enjoying it so much that I continued with it for February too. Then, forcing myself to have a change, I started March with the Visconti Rembrandt. I am still using it now. By the end of August, I had been using the Rembrandt almost every day for six months, barring a few days when I went away and took other pens for holiday journaling.
As for ink, I have been using it with Kaweco blue cartridges. I had a stash of these, acquired on buying Kaweco pens, particularly the Perkeo of which I have several. With each purchase, there would be four new Kaweco blue cartridges, with the Kaweco name along the side. I particularly liked this ink and kept these cartridges in a Kaweco tin, separate from my hoard of generic blue standard international cartridges.
Since 9 February 2022, I have filled the Rembrandt eight times with these cartridges and am down to my last one. I plan to switch to Kaweco midnight blue next, as I have a box waiting. I will never get through all my ink, but it feels satisfying to have used up these Kaweco blues, at least.
Whilst using a standard international cartridge, the Rembrandt has space to carry a spare. The spare cartridge does rattle around though, and to stop this I cut a small cube of rubber from an eraser and dropped it into the back of the barrel. Be careful with this however: too large a piece and it will jam inside and you will not be able to get it out again unless you break it up with a cocktail stick.
I should mention the chrome section of the Rembrandt. Generally, I am not a fan of slippery metal sections. For this reason I have avoided the Lamy Studio (apart from the brushed steel version with the black rubberised grip section). But in all fairness, the Rembrandt’s shiny plated metal section has not been a problem for me at all. My grip on the pen does not slip. I do not have trouble controlling the nib or stopping it from rotating left or right. I think that this may be partly because the section and the nib are both relatively short and when I hold the pen, my thumb still rests on the purple barrel, serving to anchor the pen and stop it from rotating in my hands.
When I first got the pen, I preferred using it with the cap posted, but my habit has changed and I now use it unposted. If I had been put off buying the Rembrandt because of its metal section, then I would have missed out. The magnetic cap fastening still works well and is quick and convenient. It makes for a grip area free of any sharp step or screw threads.
Above, all, the pen writes really well. I get no hard starts. I did adjust the nib slightly when it first arrived, to ease open the gap between the tines to improve flow to my taste, but having done this in the first few days, the pen has written smoothly and effortlessly ever since and works well with the Kaweco blue cartridges.
As for the Pineider Avatar in its vibrant Lipstick Red, I still have it and it is a beauty. It has the “Wow factor” which the Rembrandt lacks and got the best admiring looks at our London pen club. Yet the Rembrandt has proved itself a solid performer over time and deserves credit for that.
