24mm between the Lugs and thin hole Tropic strap

[AMK000]

Guys ,

I have this question.

I have a watch with 24mm between the lugs where I want to fit a rubber Tropic (similar) strap has that thin holes (for the spring bars to pass through)

1) What size of spring bars do I need ?? 24mm, 26 or 28 mm ?? (it all depends how you measure them non-depressed or depressed).

2) What is the thinnest diameter that I can find ?? 1mm , 1,30 mm or 1,50 mm ??

(that tropic has a very thin hole and trying to push in to it a 1,75mm or 2,00 mm dia spring bars , ....decreases the size of the strap ..to something like 23 mm and also its hard to take them out later)

Many thanks for the help guys
