I have a early wristwatch made by Longines in my Collection. The silvercase with a hallmark from England. Year=1905. Casenumber= 4808123. Movement caliber= 1184N.

When was this caliber produced?

The case number usually matches the movement (serial) number on these early Longines and a serial number of 4808123 dates this piece to about 1929. I would be interested to see a picture of the hallmarks as 1905 is quite early for a wristwatch. Also, a picture of the numbers by the balance cock may be helpful as well.

 

The movement might have come from a lady's pocketwatch and was mated at a later date. Pretty common with these types of watches.

Caliber 11.84N - first produced in 1909, it was a thinner version of the 11.84 from 1899.
Width: 11.5''' . 26.0 mm Height 4.1 mm

 

I believe that the dial and hands are original to the movement and appear to be for a wristwatch. The hinged caseback is odd for 1929 however the flat hairspring is indicative of the late twenties.

I will retrieve an extract, using the case number, and see if it leads anywhere.

 

Hi,

Thank you for interesting information. This is a great forum !
I am rather sure this is an original wristwatch. I will take some better photos during the weekend and come back. The year is a mysteri. I will check the hallmark (Sheffield) and year (?) again. Perhaps my interpretation of year is wrong...

If the case was mated to the movement as I suspect, the serial numbers will designate different years. Longines serial numbers are easy as most of us have a chart, but a casemaker's serial numbers will be completely different.

The 11.84N was first produced in 1909 so there's no way it can be from 1905. Please get us the caliber's serial number.

 

Interestingly, Longines do not want to provide an extract without photographs of the watch.

 

I am afraid I was wrong reg. the hallmarks and the age of this watc.

I checked the watch closer today (pictures below). The silvercase is marked with AB (Arthur Baume)? and London importmark. Year 1928?. Casenumber is 4808123. Movement with caliber: 1184.N Movement is marked "B&Co" (Baume Co?). There is no movementnumber visible..

Thanks for the photographs!

I agree that the "n" date letter, likely corresponds to 1928, which is probably when the movement was manufactured as well. The "AB" is definitely Arthur Baume and the B&Co seems to be expected according to David Boettcher's website: http://www.vintagewatchstraps.com/sponsorsmarks.php
