Baumgartner BFG 866 - Removing centre seconds wheel


Recommended Posts

Thanks Jon. I've recently completed a similar economy BFG movement that is in my wife's childhood watch.  I was flying blind on best pratcies so tried to use general principles. I missed lubrication of the impulse but did sheepishly utilize a minimum of oil for the pallet pivots. Fortunately I haven't closed the case since I'm waiting for an upgraded crystal so can still address the impulse...
