One you don't see too often.

Caseback.

Picture of crown side.

Thank you for the images. It's one mil-watch I have no experiance with. Does it hack?

Best regards,

Greg

I believe the pictures posted by James above is the same watch that I bought recently. I have only seen it couple of times in the past few years and appear to be rarer than the AC weems. I wonder if any body know many of this actually been produced.

The case is slightly bigger then the Weems, at ~31mm, and is basically identical to the 3-piece keystone case used in the other A11s.

The issue s/n on the caseback is 41-505 which matched the production date of the movement no 6076270. As opposed to Weems, it has has a fully hackable 12L movement (12.68N) via a hacking spring beneath the balance wheel. The caseback marking now included the full specification no. 94-27834 instead of just 27834 in the earlier Weems model.

Below are some side by side shots with the Weems I posted earlier.

This Longines has fascinated and evaded me for a long time, but I eventualiy did succeed in my quest

Longines A-11

Hi Werner

Looks like a nice Longines Type A-11. Appears the leather strap has been attached since the 1940s as well - looks great!

All the best, Ken
