As you can see, the SLA025J1 appears to a class to itself. It has a unique case construction, deeper water rating and uses a higher caliber movement.



In terms of comfort, in my opinion, the SLA017J1 is a clear winner. Its smaller dimensions makes it more suited for all occasions compared to the other two. For more information, please visit the complete review I've made on each watch.
