Poljot caliber 2616 (2616.1H) is a vintage automatic watch movement that was produced by First Moscow Watch Factory in the Soviet Union (Russia). These movements were in production from circa 1970s to 1980s.

Some of the topics covered in this caliber listing:

2616.1H Vs 2616.2H:

You may see a caliber 2616.2H (sometimes written 2616.2N) with 23 jewels. This .2H designation indicates an evolution or version upgrade to the base 2616.

Difference between 1Н and 1N:

The “H” is Cyrillic and the “N” is Roman. The Poljot H and N designations are often confused and/or used interchangeably.

It actually isn’t an H, it is a Cyrillic letter En (written as Н). Learn all about this letter or sound on Wikipedia here.

Changing the date:

The Poljot 2616 does not have a quickset date. To advance the datewheel, turn the crown from 8:00PM to past 12:00AM, back to 8:00PM then past 12:00AM again. Each action like this will change the date by one day. This operation does not work in reverse.

Day/Date?

You may see some watches described as being 2616.1H, but with a day/date calendar complication. The 2616.1H is listed as just having a date, whereas the Poljot 2627 (2627H) was equipped with a day of the week in addition to the date.
