I realized that the capacitors and also the board layout look very different from yours. I only had one 47uF and one 220 uF and both looked very modern. I thought it wouldn't make sense to replace them as they still looked fine.

As for the watch, I have a 200ohm resistor around which it looked pretty black. However, I could test it and so I assumed it must be ok.

What is your opinion on replacing these resistors and capacitors?

Thanks!
I would replace those capacitors for certain. The one says W. Germany on the side of it, I believe which puts it at the minimum of 20 some years.

If the resistor(s) don't look damaged or harmed in any way I would not bother replacing them. The capacitors are what can age and fail.
