Poljot Alarm 2612.1 Movement

Post by roo7 » 22 Apr 2011 20:42

My first CCCP watch is the Poljot Mechanical Alarm, caliber 2612.1. (It's also my second mechanical watch.)

When I first received it, I was amazed by the rattling of the alarm.

How it works
I'm not well verse in the parts and the terminology of watch movements, so please correct me if I'm wrong. :)

The top crown at 2 o'clock is for alarm adjustment and winding.
The bottom crown at 4 o'clock is for the time adjustment and winding.

The parts
Image

1. Stud attached to caseback
2. Alarm hammer
3. Spring for alarm

Once fully wound, when the alarm is triggered, the spring will rotate the gears to vibrate the alarm hammer.

From the diagram, you can visualise the hammer going left to the watch movement and going right to the stud when the case back is screwed in.

History:

The first alarm wrist watch was first introduced in 1947 by Vulcain. The Cricket watch was also nicknamed "The Presidents' Watch", since Eisenhower, Nixon and Johnson were all loyal customers and eminent ambassadors for the Cricket.

In 1959, 1st Moscow Watch Factory developed the first Soviet Wrist alarm clock "signal" 2612 ("Flight"). It was almost a copy of the A.Schild 1475. (I can't find much information on the AS and Poljot link)

In 1978, a new mechanism of 2612.1 has come to replace them.

So far, I have identified the following key differences on both movements.

Image
- serial number on the barrel bridge
- the 1MWF logo on the wheel bridge
- no "2612" or "SU" markings.

Image
- "2612.1" on the barrel bridge
- no serial numbers marking
- SU on the wheel bridge

Locally, I think it's tough, so far I haven't seen them locally, you can try your luck at CSC or ATC. Most of my Russians are from eBay.
