Behold the amazing Heuer Calculator of 1975. The bezel is a slide rule! And it's in the process of doing an infinite number of calculations simultaneously: everything times 23. 17 times 23, for example, as you can see is 391.

Here's where you can see that 23 * 17 = 391. Actually all you can see is that it's a little over a number whose first two digits are 3 and 9. But it can't be 3.9 or 3900. And you know the last digit has to be a 1. So 391.

This thing is a monster by golden age watch standards: 45.5 mm in diameter and 15.5 mm thick, and all of that solid steel judging from the weight of it. It's over 100 g. But this watch has an excuse for being so huge: the precision of a slide rule depends on its length.

@paulg I'm sorry I don't understand how you read this. I'm interested. What am I looking at ?
@paulg I'm looking at this as if I have any idea how to use a slide rule.
Cool watch though
@paulg I’ll trade my panerai I never wear lol I don’t know shit about watches l
@paulg Cool! What are you calculating?
@paulg I am way too broke for this conversation.
