Ardmore Alarm, ca. 1906
The Venus 230 movement is one of my favorite alarms to use - straightforward operation, and thoughtfully designed to make it difficult to accidentally reset the alarm time when the alarm is armed. The indicator window at 9 o'clock is a nice bonus, and the fact that the armed status on this one is luminous is just cool. The fact that the brand name sounds like something out of Lovecraft is also appreciated.
