Been wanting one of these for a while (even though it isn't a 'proper' Elgin). It came in a lot with another Swiss Elgin of gargantuan proportions.
Had to replace the calendar jumper spring and stem, but going great and on my wrist for the day. They both need a little crystal work to tidy them up.
I admit, it was the sextant that first got me , a few scrapes that need polishing out.
And, finally wrist shot...
Sorry, no movement shots yet - I'll add them later (forgot to grab some when they were open).
