Sun out finally. Cracked these two out of long term hibernation. Both started first time, running sweetly and looking good. Happy days.


Something looks awfully familiar in your post!😉



I just can’t figure out what it is.😵‍💫

Anyway, today’s watch...

Tell me more about this watch. I am unclear about the outer two sets of markings. Why the pi?

It's a slide rule - effectively a mechanical analog computer. From the days before scientific calculators, laptops and iPhones. Found on Breitling Navitimer, Gallet Excel-O-Graph and Heuer Calculator amongst others. Used by pilots (as an example) to calculate fuel required, used and remaining, amongst other critical, complicated calculations.

Ever since I put this watch on the 1171 I’ve developed a whole new love for it. Pretty much wore it strait for the last week. Should’ve done this years ago.
