This is the front entrance - there is a nice parking lot right out front with many spaces available. I parked in front momentarily to include my vehicle in the picture.
Many of the rooms withing the museum are themed to varying degrees and decorated nicely. Since the museum is just minutes away from Lancaster there is a nice selection of historical items from Hamilton Watch Company.
To the left is the Grand Statuary Clock manufactured by Eugène Farcot in Paris. Eugène specialized in conical pendulum clocks and was awarded nearly two dozen patents for his horological inventions. And just in case you are interested, the museum contains and operates the Engle Monumental Clock which is also referred to as the 8th Wonder.
Here is a section of the library and research center. If you wish to spend time in this area I would recommend another full day, or more.
