Citizen’s alarm series - like this 1960's Citizen Phynox alarm watch here - represent a balance of a classically-shaped 1960’s mechanical chronograph, ie: not too thin, nor too thick.
The Citizen here, with a gently curved caseback that allows the watch to sit rather comfortably on the wrist, features a caseback that snaps into position to place it in a specific position to allow the alarm to ring as designed.
This Citizen features two crowns – one for the time at 4 o’clock and a second for the alarm at 2 o’clock; after winding the alarm crown, it is set by pulling the crown to the second position, counterclockwise, and once set, left in the second position (akin to the Seiko Bell Matic).
Pressing this crown in while the alarm is ringing will halt it. The alarm works via a small hammer mounted on the movement, which strikes a pin on the inside of the case back.
This Citizen alarm comes on a vintage stainless-steel bracelet, and with a leather pass-through strap, springbar tool, and rugged travel case.
