The joints will be strong enough IF you follow the golden rules of
soldering (clean, well fitted, fluxed, heat quickly, don’t overheat,
remove heat when you see solder flow, etc, etc).
Make sure your bezel is not made of metal which is too thin, and that
the jump ring is also not too thin. I would personally use hard
solder and file a little bit out of the jump ring to correspond to
the curvature (if any) of the bezel setting. That way, there will be
a longer and stronger solder joint.
