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.

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.
