without a doubt, ages ago I bought a Bergeon 6767-F due to constantly changing watch straps. Also the fact that my Orient Mako 2 has curved spring bars which made it a bastard to replace.
It's well worth buying a couple of spring bar tools, decent screwdrivers and a cheap loupe if you swap straps a lot. Saves a lot of case scratches and swearing.
