Movement w/ both triangle and square date symbol, but model not released until 1929? Has Jan 11, 1927 patent date in case back. 15J USA Adj
{updated to new DB format, case SN corrected, and images added 2012/03/22}
{updated From 1929 lone eagle to non-conforming to indicate movement swap w/ 1935/36 10AN based on comments from admin 2012/03/24}
In reply to i really the white on this by Ellierose
Possible triple date code stamp of machine stamped triangle, hand stamped square-possibly stamped over another hand stamped symbol which I can't make out. Could be anything, but it appears square was stamped over the top of what ever it is.
So 1926/1927 movement Year of watch updated to 1929 based on Case Serial Number
In reply to Will, the movement is not by mybulova_admin
Thanks Admin I don't think I've looked at this movement, watch or record too close for years....I see it's the 96th record in the watch database....and I really made a mess of things back then. I'll update.
I just took photos of it, added them, and didn't even look at the photos....my bad.
Here's where that non-conforming comes in handy...but the darned thing sure looks like a lone eagle....sans movement replacement at least ten years after 1926....probably more recent than that.
So ideas on what forced entry to put in for manufacture date w/ this watch record. Can't decide what to put, since later mvent replacement. Wouldn't make sense to have a manufacture date?
This begs some other questions which we will see again and again w/ these types of watches.
Suggestions anyone/all?
Maybe this watch doesn't' belong in the database at all, short of education and a learning curve for how to address these things. There are several examples of a "conforming and production correct" 1929 lone eagles in the database. Thousands of combinations of "non conforming" are possible. At very least, the star rating for these are moot?
It serves no purpose to have a three star non conforming 1928-1936 dated lone eagle. what ever that would be. ...and for my own watches, I have never been in favor of changing back to period correct movement etc. For me, it would be a recent marriage to period correct....not a reproduction, but a reconstruction not even using NOS parts. Fine line for me personally, but I'm not saying if someone/anyone did this it would not be "as original". I just stray away from these marriages.
If we are trying to look for movement serial number correlations to cases and series/ID's, adding another 1926 or 27 10AN is a problem from point of view of mvnt SN.
In reply to Will it is what it is a Lone by mybulova_admin
OK I'll change it back from Non-Conforming to Lone Eagle. The comments will address differences. Don't know what I should enter for the manufacturer year in the record. Case SN is for model/case but it would make no sense to have this as 1936 Lone Eagle. Just doesn't quite feel right. Personally I won't be giving it more than one star because I believe a two or three star rating would be misleading for this example.
Suggestions?
