Antique and Vintage Mechanical Clocks

During my travels through Ontario, I acquired a Seth Thomas Regulator #2, one of my newest additions. I discovered this clock in Bloomfield, a quaint village just minutes from Picton, a major hub in Prince Edward County renowned for its many wineries.

I first spotted the clock during a summer visit to the local antique shop and deliberated over the purchase for quite some time before finally deciding to take the plunge in the fall. These clocks are a rare find, and with the price being right and the clock in excellent condition, it felt like an opportunity I couldn’t pass up.

Perhaps best known as one of the most common regulator clocks in America, the Seth Thomas Regulator #2 was a fixture in many railway stations across the country during the last century—a testament to its accuracy and dependability. Robust, precise, well-engineered, and reliable, this timepiece was manufactured by Seth Thomas from 1860 to 1950, an impressive production run of 90 years. Few clocks can boast such longevity. It is an iconic American clock, and every serious clock collector aspires to own one.

A classic style, the #2 changed very little over the years. However, certain design characteristics help date the clock. The following identification guide describes dial and case characteristics that will aid in identifying the approximate year the clock was made.

The most distinctive visible characteristic is the design of the base.

Aside from the distinctive base, all but the earliest #2s had the pendulum mounted in the rear with “T” hands.

The chart also lists the limited run reissue in 1976. Most Seth Thomas aficionados would agree that while the reissue is a handsome and well-made clock that is a testament to the original it is not in the same realm as an authentic Regulator #2 and the prices for these versions reflect accordingly. However, those who have the reissue seem to be pleased with their acquisition.

ccording to the chart, my clock was made between 1922 and 1929 and features a base reminiscent of the earlier 1860 version of the #2. It has Arabic numerals with spade hands, and the bow-tie connecting the wooden dial bezel to the drop is a single piece (earlier versions featured a three-piece bow-tie). The clock includes a second hand positioned 2 inches above the center cannon; however, it is not a true second hand, as it runs off the escapement and takes 80 beats to complete a “minute.”

Measuring 36 ½ inches in height, the clock is veneered in mahogany. The movement is stamped with “77A” in the bottom right corner, with the letter “K” underneath, but it bears no other markings. While some versions of the 77 movement have lantern pinions, this one is equipped with cut pinions.

Are there issues with this clock? Certainly, it is over 90 years old!  There is minor loss on the dial, no label, a finish that has lost its luster and paint splatter on the top of the case not visible from the front. Is it really so hard removing a clock when painting a room!

Is it Perfect?

I brought this clock from Ontario to Nova Scotia by car. Removing the pendulum for transport is not a particularly simple process but if you are familiar with the pendulum arrangement on a typical weight-driven Vienna Regulator this one is no different. Like Viennas, the pendulum is hung behind the movement.

Both the weight and the pendulum must be removed for transport. There is many a story of broken glass when weight and pendulum are free to move around inside the case. To remove the weight, simply unhook it from the cable wheel.

To remove the pendulum the movement must be taken out. First, the hands are taken off. In this version, the minute hand is held in place with a nut. Older ones have a pin. There are 8 small screws that hold the dial in place. Once the dial is removed, two larger screws on the wooden second-hand rail are removed. Four cylindrical column posts hold the movement in place. Unscrew these beginning with the bottom two and lift the movement out. Once the movement is out, the pendulum can be unhooked from its suspension spring. The entire process takes less than five minutes.

The trapezoid 77A movement with maintaining power in this clock looks clean. There is evidence of having been worked on in the past as there are 4 punch marks around the winding arbour to close the hole; a common practice in the past to close a pivot hole. Otherwise, the movement looks very good.

Getting the clock to run reliably was a challenge and it took a week or so to sort it out. The clock would run for a few minutes and stop.

Following a process of elimination, I removed the movement, inspected it for wear, found very little, oiled the pivots, and returned the movement to the case. I installed the dial, then the hands. The clock would run for a few minutes and stop. I removed the hands and dial; left the dial off but reinstalled the hands. Still, it would run only a few minutes. I then took the dial and hands off. I ran the movement for four days to eliminate any underlying issues and to convince myself that the problem lay in the positioning of the hands. The problem was definitely with the positioning of the hands.

On day five, I put the dial back on, then the second hand ensuring that there was sufficient clearance between the second hand and the face. Next, I put the hour hand on the pipe and pressed it in far enough to clear both the second hand and the minute hand. I attached the minute hand, inspected it for sufficient clearance, and screwed it in place. I started the clock.

Success at last! Regulating the clock is fairly simple and is achieved by turning the rating nut on the bottom of the pendulum. This clock must be level and in beat to function properly.

I used Murphy’s Soap to clean the grease and grime from the case. I chose to leave the paint splatter intact, as it adds a bit of character to the clock. Additionally, I polished the brass weight and pendulum bob to restore their shine.

This clock boasts a striking appearance and a rich, illustrious history, making it a perfect addition to the front entrance of our home. Unfortunately, its journey over the past 90+ years remains a mystery.

The question of whether it qualifies as a “true regulator” is a debate for another time.
