Can I change the steel strap to a Casio leather strap?

I swapped the original steel wristband for a 20mm nato strap. There is a very slight gap, probably about one millimeter on each side.

hola el producto es 100% original y en cuantas días llega a la ciudad de bagua - peru

Hola el producto es 100% Original, muy elegante y funcional. Yo estoy afiliado a una empresa que brinda el servicio de importación y llegó a mi país (Costa Rica) en 18 días.

whats the difference between this and the non EF model?

EF I believe stands for the illumination material of the the hands of a chronograph watch. Stock numbers on products normally describe products which they are assigned to. They are not random numbers, they are descriptions. I hope that helps.
