And before those climbers had Explorers and Oyster Quartz they used Oyster Perpetuals:

Many thanks Hannes. And there was also another famous mountaineer who wore an Oyster Perpetual:

Luis Trenker (*1892, +1990), famous author, actor and director of mountain films. Trenker was a also a phantastic narrator and when he was narrating it was nearly impossible to stop him.

Trenker has worn his Oyster Perpetual from the late 50ies until his dead in 1990. As you can see he wore his Rolex (when I remember it right it was a Zephyr) above the cuff of his shirt, as it was also done by Giovanni Agnelli.
