The Calibre 489 was massively produced from 1950 to 1958, as some 47 500 movements came from the Manufacture at this moment.
You will notice that on the following watches, the reference of this Calibre slightly changes, as it is mentionned P 489/1.
It is exactly the same movement, but the P stands for Parachoc ( shock protected ).
Exit the Tubular shaped lugs, and welcome the classic straight or teardrop lugs, a nice evocation of the style and design from the fifties.
You will also notice, like on the very first Memovox, the variatons on the design of the dial, with indexes and numbers, indexes alone, numbers alone etc.
- The 3151 ( this watch was produced in 1952, while the reference was in the catalog till 1956 ) .
Radium index numbers and Losange hands:
- E 850:
This reference was produced from 1954 to 1958 in 4262 pieces.
As often, several dial variations saw the light.
Nice large bezel, thick case and lugs, for this 33 mm watch.
Here a superb model, with its Dauphine Hands, and the 6 / 12 applied index numbers.
- E 851:
As written on this catalogue from the mid fifties, the E 851 is 2 mm bigger than the E 850, and was available in solid gold or stainless steel.
The watch pictured below was released in 1954:
And this one, in 1953:
Please note that the E stands for etanche ( water resistant ) which means that the case back of the " E " Refs is screwed, at the contrary of the non " E " References, which have a snap bakc case.
- And to end, a last reference, the Memovox 3154, housing a movement which is close to the Cal 489, the Cal 601.
Here, a picture of the Cal 601 provided by our friend Greg B:
The Cal 601 was made in a quantity of 2 000 pieces.
The particularity of the watch to which it is related is that the Alarm disk has been replaced by an Alarm hand.
The case is gold plated.
This particular watch was released in 1952.
