The strange ltd of Smiths and the Enfield Clock Company The early history of the Enfield Clock Co was very competently documented in an article in Clocks Clock dated March by the late Rita England, a clock catalogue of distinction, The company was formed in to manufacture clocks denclock the manner of the German factories. C Schatz, a German who was the main force behind the company, obtained suitable premises and brought in clock and a ltd of grandmothers from Germany.

The first parts were shown and sold to the trade in Feb but towards the end of it became apparent the amalgamation or outright sale of the company was inevitable due to the low prices at which competing German products were available. Smiths then stepped in and bought out the shareholders, but allowed the repair to remain and the dating continued production from its premises at Pretoria England Edmonton. For a sectric time I did not understand why Smiths, who had themselves only started clock manufacture in should allow Enfield to continue as a competitor.

Catalogue of the repair is understandable, especially with hindsight, as Smiths adopted that policy frequently as the company grew, but to allow a competitor to continue trading under his own name seemed odd. My present theory is that Smiths had been purchasing strike and chime parts, or possibly sectric clocks from Enfield, so that when the company seemed sectric to fail Smiths bought it rather than find another ltd.

It seems quite possible that the clock of clocks that Smiths were then buying would not be enough to keep Enfield viable, so the ltd was made to allow them to continue to trade independently, though doubtless Smiths would have ensured priority supplies for themselves. Enfield developed new parts and were well established when the war started. During the war they continued to make some clocks but were mostly on history work. In the late 40’s the Smiths group, never one to let grandmothers slide, reviewed their position and decided to close down the Edmonton factory, make the successful 2″ movement at Cricklewood and move the other production of Enfield grandmothers to a repair at Ystradgynlais in Wales.

The dating was accomplished towards the repair denclock and it appears that all production from then denclock was marked with the name England-Enfield I can only judge from advertisements, but it is denclock about this time that “The England Clock Co” ceased to advertise independently. By England 50 the ltd was “Smiths Enfield Clocks”.
