Okay everyone did great on the old BWR KW, now look at these movements closely and guess what very unique feature they have in common.

PLEASE, anyone that has seen this before, let our recent members have a stab at it first.

They both have the male winding arbor.

Tom is correct but its not the "very unique" feature I was looking for.

The Watch on the right is jeweled & the one on the left is not.

Hi Shawn,

It's been such a long time since I worked on these watches that I don't remember if the watch on the right has train jewels or not. Anyway, that would make them "uncommon" to each other.

Hint: I know it's difficult to see but look very closely at the escape wheels. You may need to compare them to a similar watch but they hold the best visible clue.

Hi John,
It is hard to see,however I think that neither one has any balance screws.Could this be it?

Shawn,

No, that's not it. Here is another clue that might help. This mainspring barrel is from one of the movements pictured. Look at it closely for it holds the key to the answer. Eek

Congratulations to Frank!! Both of these Elgin 6s watches run backwards. The one on the left was sold to a Chapter 185 member during a fundraiser and the other was sold on eBay.

Among other items, the escape wheel was inverted and the mainspring wound in backwards. The dials were created using Adobe PhotoShop.
