From 1952 I have seen quite few Rolex documentation.
Just a small amount of sales cataloges survived until today - and this one is a very special in Enmglish and Spanish.
Why bilingual in English and Spanish - wouldn't the latinamerican and spanish market justify a Spanish only version?

But now let's have a look at the ladys models of the old times:































What someone notices is the small variability in the style, nearly all models are "camouflaged" as a bracelet.
Also the recommendation for oiling service intervals are interesting - gents watches every 18 months, ladys every 12 months.
