Today I successfully found a workaround for replacing the crown seal on the 6105: I wrapped the stem with teflon tape and added in a little silicone grease and bob's your uncle. I pressure tested it for 5 minutes under 6 BAR and it held like a champ. I don't dive with this one but I am no longer afraid to splish a few splashes on it while washing the dishes. Cheers!
