    BubbleBack versus Ovetto

    I posted below, in a response on another forum, thought it may be interesting to some here.

    Bubbleback was a term used to describe the early Rolex Perpetual models, due to the thickness of the case used to house the oversized Auto-Rotor movement.
    Actually there are 5 models of Perpetual movements, each with different case back, the very first model (1933 to 1935) was not looking like a 'bubbleback' case but more like the bottom of a 'coke can'

    Here is a picture of the earliest and rarest Rolex Perpetual (a DIDACTIC 1933) versus a 'BUBBLEBACK' 1949
    You can see the 'DIDACTIC' is very less 'Ovetto'





    I own both of these

    Nice pair of case backs.
    Why is the 'DIDACTIC' very less 'Ovetto' and what does that mean? is it to do with being egg shaped?

    'OVETTO' is Italian for 'little egg' the affectionate name due to the shape of a 'Bubbleback' case.
    However Rolex first automatics in Q4 1933 and 1934 did NOT actually have that shape, the true bubbleback appeared around 1938. At this time I expect out of efficiency or less bearing wear the rotor was much more angled - and 'OVETTO' was named
    The first Rolex called 'DIDACTICS' actually look more like the bottom of a Pepsi Cola tin!

    The back sides are very nice but any chance of a glimpse of their faces.
