Pelikan Erase, erasable pen

I don't understand why is there a need for a pen that can be erased instead of using a pencil, but for the sake of the test let's go on with the Pelikan erase

TEST #1: Writing

Writing with the pen feels creamy, but the ink is not coming out with consistency. If you take a look at the picture above you can see numerous parts of the text where the pen skipped, or where the line density is different from normal.

Taking apart a Citizen watch

In the previous post, I was writing about a Citizen automatic 21 Jewels day and date watch that I bought on eBay for 11.5 dollars. The watch came with a small problem, the second's hand is not staying in place. At the moment, because the watch was not winded enough, I thought it was keeping horrible time. I found out later it is running very well.
So the only reasonable thing to do was open the watch and see what can be done. The first obstacle was removing the crown and stem to take out the mechanism. For that I didn't need tools, just a steel sheet to open the back, and a Rotring Tikky to press the stem release button. (see previous post)
I put the second's hand but it does not want to stay, it's a two-hand watch now. But this was not all. The manual date/day change was a bit scratchy, so I thought it just needs a few twists to loosen it. I did the day/date change while the hands of the watch were not in the correct position. This caused another problem. The most serious one.
The day/date can't be changed manually anymore. I decided to take the Citizen watch apart, even though I didn't open a watch before.

Step one, buy a set of watch screwdrivers. 
I bought the cheapest set in the world. Under 2 €.
