Is my winding crown not genuine?

[lawrencesiu]

So my dad gave me his Explorer 2 16570 he brought back in 1990. He had it serviced 7 years ago but was from an unknown 3rd party.

Having looked around and comparing my Explorer 2 Ive noticed my winding crown logo is a bit smaller.

Just wanted to make sure if the 3rd party might have given the watch a non-genuine watch crown? I could be overthinking and this might be the same crown that came with it but wanted to know your opinion.

Do rolex have different sized crown logos?
