PN - As do I. Need to send it off to have the bezel changed though, the markings are all scuffed. I never thought I'd be one to use a slide rule, but for quick back-of-fag-packet calculations, it's been far more useful than I had thought.
The "never needs a battery, never needs to be set" aspect is what appealed. Also the ease of changing the analogue hands between timezones. I use that quite a bit.
