    Longines Prima pocket watch 19.71N

    Hello,

    I am looking for some information regarding the "Prima" label on the dial of this 1922 Longines pocket watch. After some research on the Internet, I found some similarities with a Zenith pocket watch with the same dial and "Prima" label. I also found out that in 1928, Rolex was using a classification "Prima", "Ultra Prima" and "Extra Prima". Is there a link ? If you have any information, I would appreciate your help.

    Prima Tula watch and if I look a the movement it had at least 16 jewels probably 17 and an excenter regulage. Therefore I guess the "prima" is for a higher level of movement standart. Mikrolisk says 1919 as the year of production for the movement. Other uses also the term "prima" for smoothly upgradet movements. I'm not used to Longines to see if other nicety excist.

    Hello Hartmut,

    I read with a lot of interest your post regarding the Zenith Prima and its quality term used for this pocket watch and its micro regulation system by Charles Rosat. A few years ago, I posted a question regarding a Longines 19.71N niello pocket watch that I sent back to Longines for repair. I was asking what was the meaning of the Prima label written on the dial. Can we assume that this Longines has the same micro regulation ? I noticed actually a lot of similarities between the Zenith and Longines pocket watches of this era... Thank you, Have a good day! Jean-Mathieu

    Hi,
    I don't know if other brands had similar grading, but in the early 20th century Longines simple watches (i.e. without complications) were made in several grades : the basic ones had no name, then there was Prima and after Extra. On top was the chronometer grade. But those grades were not always written on the dial.
    You can see here a german sales brochure from the 1910s with all the grades available : https://www.vintagelongines.com/index.html#brochure1

    Hello, this brochure is really interesting. It looks like I found the «.Prima.» explanation with one of the sketch displayed! Thanks a lot! Best Regards Jean-Mathieu

    Hello, Enrico!
    Please excuse me for jumping in!
    Referring to the image: please, do you happen to have Longines „Fourniturenblatt“ for 19.71N and 19.73N?
    It would be of great help – see this thread…
    And do you know which calibers use the same balance wheel as19.73N?
    Thank you!
