Same in Italy, tax report is actually not needed if you're a regular employee and don't have anything else to declare. If you do, each year you get a pre-filled form on which you only need to add your deductible expenses and/or additional income outside the regular employment.
I guess it depends on what affordable means to you. You can find quite a few Orient watches without date at really reasonable prices, a couple of Timex too. If you're willing to spend a bit more you can also get various no-date Hamilton.
