So I wanted to change the bracelet on the Invicta Pro Diver I received for reaching level 9 to a rubber strap to give it a more sporty look. I do like the look of it, but I don't like the gap it creates between the case/lugs. I'm thinking I could go with a curved ended strap to give it a more fitted look, but am wondering if curved ends are all the same or are they different curve diameters and will possibly not fit right. I know
