So I just got this Ansonia clock from a local yardsale. For $30. It is in nice condition. It ran without the pendulum (making the clock run super fast) but did not run with the pendulum attached. I raised one side of the clock up a bit (letting that raised side sit on the back cover. The clock not only worked with the pendulum but kept great time. As the clock was sitting on a level surface before I raised it and it was not working, this told me that it’s issue was due to a beat issue. I…

A Yard Sale Ansonia Clock

Crew, In an effort to spend less time on my phone, I’m looking for an alarm clock so that I can leave my phone in the other room.

I like watches, obviously, so it seems a shame to put some hunk of glowing cheap plastic on my nightstand. What should I be looking for? Brands? Search terms? Sources?

I’m drawn to older stuff like the Oris below, but I’m open to other options like the “flip” alarm clocks, etc.

Thanks in advance!

I know cliche, but when cleaning out the family house basement I found amongst other things several watches and a clock. The watches im going to try to identify a bit myself before asking for help, but i am hoping to get a hand with this clock… pictures below.

The serial number is very worn away. I think it is 14_382. I wouldn’t swear to that and i think theres a number worn away between the 4 and 3. It is definitely mechanical and does still work. It also reads “chelsea clock company…

From a survey of the literature, Seiko has used two methods:

1. In 1996, Seiko published one method involving a spring and a viscous damper:
“we adopted a method in which a third wheel, whose gear and pinion are elastically connected by a coil spring, and a fourth wheel, whose rotational load is applied by the viscous resistance of grease, are installed in the gear train”

The spring…

Following my ‘starter’ GPS clock, I have acquired another from the same makers:

My cost: under $300.

This version foregoes any display but adds an oven controlled quartz oscillator (OCXO). This keeps the XO within a tight temperature band in order to stabilize its rate, both when the clock is autonomous and for the more usual application of correctly subdividing the 1 pulse/second…
