The Jubilé Atmos is dated 1983 (and not 58, what is logical as jubilé means 50th anniversary)
The Jubilé Atmos caliber is the 550, the clock looks externally like an Atmos I (but with a gas cartridge in place of mercury.)
In fact technically the watch movement is the same as the cal 526/528 and the clock movement also shares numerous parts with cal 528/529
Numbering is specific and out of the usual range (1500 produced).
