Bulova 1974 Set-O-Matic

We have had discussions previously about Set o Matic being a function rather than a name although we see both ads as Set-O-Matics but usually this would be in a model line like Clipper or President.   Yours is very close to this 1974 ad as a President.  I am still digging for a match.   Unfortunately not an exact match but close.   

Não acho que o relógio no anúncio corresponda ao relógio em questão. Sem um anúncio, eu estaria inclinado a rotular este relógio como modelo 'Set-O-Matic', já que usamos essa designação no passado.

I don't think the watch in the advertisement matches the subject watch. Without an advertisement I would be inclined to label this watch as 'Set-O-Matic' model  as we have used that designation in the past.

Probably best to continue to group these, until we can find an official linebook entry that deterrmines an actual model name.
