IMHO strap changes are easy
small strap tool widely available
there will be much opinion on what brand
i have several cheapies that came w/ various kits i have bought
one tip broke, but it came w/ 2 spares
Bergeon is considered the best, but i never got around to buying one
changing straps lets you totally change the look of the watch
i have Isofrane (black & orange), Hornback, silocone (orange, black & blue) digital camo, natos, zulus and a custom leather and canvas inbound
Straps are a inexpensive (well sometimes

way to play around w/ your watch(s)
DONT put 24mm tubes on your watch, Bes will have to cut them off for you

(tubes are common on some straps, goes in tunnel on strap, then springbar goes inside)
24mm tubes on a 24mm lug will fit BUT no room to remove em...
enjoy buddy
