Self Winding Clock Co. Slave (Secondary) Clocks. Uncommon and very interesting.

IBM and Standard Electric Time had reliable master clock-slave clock systems. And so did the Self Winding Clock Company but not much is known about their system. The various voltages and number of pulses per minute are explained. Self Winding was well known for it's master clock connection with Western Union Time Service and Subsidiary clocks but not for it's master clock-slave clock systems.

Always appreciate your detailed and knowledgeable descriptions. You're a big help to all amateur electric horologists.

i have no clue why i am only finding your channel now. your collection is magnificent, thank you for sharing your knowledge and your collection. i wish one day i could find a SWCC master, thank you for posting these videos so that the history of these clocks is preserved.

[@SelfWindingClocks]

Thank you for your very kind comment. I happy to hear these videos are informative. I do think it is important to share with others how remarkable these clocks are. SWCC master clocks do appear. Keep watching.

Thanks for another great and informative video!
Seeing a new video from you pop up today was a great way to start a day

[@SelfWindingClocks]

Thank you very much Richard. You certainly added my day.

[@SelfWindingClocks]

Make that .... you certainly added to my day.

Great to see another one of your fascinating videos. Your videos did indeed get me into collecting master clocks. I should do a video of my National Time Recorder Master Clock and two NTR programmable slaves one day.

[@SelfWindingClocks]

Thank you Matt. I love the idea that these videos help get you into master clocks. A video on your National Time Recorder Master Clock and slaves sounds very interesting. Do it!

[@theeatonskbunk]

Thanks for another interesting video. Liked and Subscribed. Is there a way one can contact you with questions about a specific clock?

[@SelfWindingClocks]

I would be happy to try to help. Pictures are important. Alan [e-mail]

Very interesting Videos! Do you know about the clock System, made/used by the german company "Telefonbau und Normalzeit"? It might be interesting for you, although it's for sure much simpler.

[@SelfWindingClocks]

Yes I know about T&N. They seem to be beautifully made. I have seen a few but never had one. Alan

[@jojo_318]

@@SelfWindingClocks I have a few Masterclocks, but I have the Fortune to live in Germany, werw they were produced. I even uploaded little clips of them in Operation to my own channel.

Amazing videos. I too am a former IBMer and history buff. I just purchased a 1919 international (IBM) school clock. Could you, would you assist me in how to get this clock running? I was in sales, and not nearly as technical as you. Much appreciated!!!

[@SelfWindingClocks]

Hi Russ, Please send me a few photos of your IBM clock and I will try to help getting the clock running. [e-mail]

[@joedyhicks9415]

Wonderful video as usual Mr Bloore.
How can I get in touch with you ? I have several questions about master clocks in general but I have come across a clock and can not find another example.
I was hoping you might be able to help.
