Today the SM 300 is going to service. I take your advice and keep crown and crystal.

If you are going to use it regularly replace both but keep the originals.
A true problem with ”keeping” the original 300 crystals are that very seldom are you able to re-install them without any damage / cracking as they are very fragile. So just think twice of being able to “put it back again” as it would never had left the watch. Just my 2 cents.

Acrylic crystals can degrade over time and lose structural integrity, especially if they have had a good dose of UV (sunlight).
One good bump could cause the crystal to shatter and you end up with bits of plastic all over the dial and hands.

For a watch of this value, I'd fit a new crystal to safeguard the innards and keep the old one in case some collector sees value in it.

Just my view.

I understand your point, but in this case i will only wear the watch on special occasions so i think the risk is minimal. 😀

Back from service (cleaning and oil), everything was in great condition but very dry .
We just changed the case gasket and nothing else. Happy to get it back, and now to decide to keep or trade 😀
