··LemaniacHi @Northernman
On these Lemania, and several others in gold from Lemania, the hammer head mark with a number in it, the number is 105.
So the casemaker was:
Les Fils de Jules Blum, from 11.07.1934 to 16.05.1974.
Based on that assumption, I presume it will not be so easy to date them.
For the chronometer model, seems to me, there was two types of case.
One with larger lugs, on case serial 20400 and 20433, and other case with thinner lugs on case numbers 20547, 20531, 20527 and 20552.
Even so I am finding extremely difficult to date them, as per my research.
Movement serial number 21176, has the case number 20547
Movement serial number 21233, has the case number 20531.
So I found no logic on sequential case numbers, has a lower serial number movement, has a higher sequential case number.
I will keep digging.
Thanks,
João
As to case serial numbers I am leaning to the conclusion that Lemania did not put too much emphasis on this.
I would guess cases were bought in batches, and fitted with movements as orders came in.
They were first and foremost a movement manufacturer. Movement serial numbers from Lemania are seemingly much more consistent.
Movement numbers in the 20xxx range (according to my very unofficial lists) would date from 1946 to 1947.
Winston Churchill’s CH27 ref 177 had movement serial 12565. It was giftet to him in Switzerland on September 19th, 1946.
In 1948 Lemania switched to 6 digit serial numbers.
