Right. Without hermetic sealing, the double oven would be negated by humidity effects. I tried to discover exactly what component was the major humidity "sensor" in the 10811, but was never able to narrow it down to anything specific. The crystal is not the humidity sensor because it is hermetic in its own package, even in the non-hermetic 10811.
