Rare Chelsea 'Crystal' Ships Bell Clock, c1909 in exceptional condition. We (the clock community) have only seen maybe three of these... and the others were totally beat up (and one had a wrong hour hand). The 'George E. Butler San Francisco' dial is also desirable to collectors. Note that the clock went back to Chelsea in 1912 for servicing, at which time it was updated to the 1912 patented gong block with improved sound, ribbed gong block and wooden sounding board in the base.
