You have the answer to your question. If you never wear it because of its glass, then no need to service it. You will not easily find a good glass, as it is not a common Geomatic.
So, either you send it to JLC for a service and a glass replacement, or you sell it.
But in this condition, you will not sell it well...
Best,
