To be more precise, JLC released the first Alarm automatic movement ever made ( all brands included ) since 1956.
This movement is referenced Cal 815, and was in production till 1966, while its Date " brother ", the Cal 825 was released 3 years after ( 1959 ) and produced till 1969, while the Cal 815 saw its production stopped in 1966.
The Cal 815:
The Cal 825:
Both of these calibres are 17 jewels bumper automatic movements, beating at 18 000 vibrations per hour, shock protected or not ( P or K prefixes ), and were produced at 17 000 pieces ( Cal 815 ) and 67 000 pieces ( Cal 825 ) with an autonomy of 45 hours, and 20 seconds for the Alarm.
Let's see the related watches in the detail.
- The Ref E 853:
This reference was in production from 1956 to 1963, and released to 11 856 pieces, in stainless steel and in solid gold.
The stainless steel:
The gold version:
Here, no date, all purity. The Great Class.
- The Reference E 855.
Certainly the most and better known reference on the different foras.
It is logical, as this watch was massively produced ( around 48 000 pieces, all metal and dials included ) fore approximatively 10 years.
What is less known is the incredible variety of E 855 made.
Yellow Gold, Rose Gold, silver dial, black dial, ebony indexes, large indexes, here is, summed in pictures the great richness of the E 855:
° The most common E 855: Applied indexes, silver dial, Dauphine hands: ( 1960 )
On its Gay Freres stainless steel bracelet, made for JLC: ( 1961 )
In black, this watch gains a lot of strenght, without loosing elegance ( 1961 )
If you're a colored gold guy, you also have a nice choice between the white and the black dial.
But wait, this is not all... Some E 855 came with the so called Ebene indexes, like this one from 1968:
And others came with larger and shorter indexes, like this one from 1969:
Both the " Ebene " and the shorter and larger indexes share the same hour and minuter hand, by the way, less elegant than the Dauphine, but this is not enough to not want them, in my opinion.
Of course, I will reserve a further post on a very special E 855 I saw, but we already be admirative in front of such a diversity inside only one reference!
