Cool! The fifth pinion design is always interesting. Yours is not a private label like the thread here, but it's a grade 6. It has that awesome Johnson's regulator, which was the first one Aurora used. I cant seem to find much info on that regulator.

The second patent regulator Aurora used (Hurds Patent regulator) was filed July 21st 1886 and granted August 30, 1887. So from my limited understanding of Aurora, since your grade 6 has the earlier regulator that would tentatively put your watch somewhere in 1885 or 86. (Please correct me if I'm way off).

Thanks for sharing.

You're quite right about this watch appearing in the wrong thread. I asked the moderator to move it to "most recent additions to your collection."
Can't comment on the dating as I'm waiting for a copy of Greg Frauenhff's booklet from the NAWACC library but I believe your estimate is correct. Just a few years prior to Aurora morphing into Hamilton.

It's a nice watch that deserves it's own thread.

Super nice Aurora. A date of 1885-86 is most likely. Railroad grade for its time. Incidentally, nearby #60975 was used in RR service on the Burlington Route in 1889/90.

Regarding Johnson's regulator, the only information I ever discovered on it was a minor mention in a period Aurora newspaper article wherein it was noted that Aurora was switching from it to Hurd's new regulator. No patent has ever turned up for it.

Being something of a ham-handed clutz I am stumped by how to open the back of this watch for a photo. The seller was kind enough to allow me to use one of his. I can use some guidance from you experts. :)

From the pictures I think the center section lifts out of the rear half of the case once the front is open.
Lift at the pendant.

Might it be this one?

Rick, it is exactly as you described it. It is nice, finally, to contribute something to this forum rather than inundating you veterans with questions. :)
