Hi all,

I recently won this Lone Eagle on eBay.  After I received it I exchanged emails with Stephen about whether it’s one of the 5000 based on the case number (6637743), and the movement, which is a 10AN and has a serial number of 227325.  Oddly, I can't find a date code on the movement, other than an arrow.  I'm aware of the arrow that is sometimes on 1926 movements.  I had commented on it recently on the 1928 President I had posted that has a 1926 9A movement with a triangle and an arrow.

So, perhaps this is another Bulova anomaly; a 1926 movement with only an arrow and no other date code?

Anyway, I just got the watch back from my watch guy.  It needed a new mainspring and it’s now up and running (and on my wrist as I post this…).  Stephen had asked me to look again to see if there was a triangle date code, and I’ve looked and looked, but all I see is the arrow.  In fact, when I took it to my watch guy, he also tried to find a date code.  He was also puzzled by the arrow, pulling out his chart with the Bulova date codes and pointing to 1937!!.   At that time we both looked and couldn't see one other than the arrow.

I’m anxious to hear what the panel thinks.  Hope it’s a 5000 LE…

David

Any update as to the possible date code?

Other than looking at the areas you had circled with the magnifiers I have, nothing new. As I mentioned, the one near the word UNADJUSTED is obscurred by the dust cover.   The dust cover was off when I took the original pictures, but then I took it in to have the mainspring replaced and he also put the dust cover back on.  If the screw obsures the date code stamp would it help if I had the screw removed so I could check more closely? Also, I expect my watch repair person has a stronger magnifier than mine, which may help.  I can take it to my watch repair guy, but I can't take the screw out on my own...

We did kind of "hijack" the thread w/ the 1st 5k theory stuff.  That's why I put the link out to the discussion to another forum post.  However, the criteria we may use for determining if this is ID'ed as a 1926 Conqueror or a 1927 Lone Eagle is almost completely based on that discussion.

David, if you are comfortable in doing so, the dust cover ring literally pops off and isn't that hard to get back up. If you are up to it, it would be good if you were able to take it off and re-examine the movement.

I'm pretty convinced I know what to ID your watch as, but for the sake of the other panel mambers it would be good to get some clarification.

I don't think removing the screw will reveal anything new as the date codes are normally in an area away from them.

Stephen,

I went to my watch guy today.  We removed the dust cover and carefully looked at the watch, especially the areas you had circled (I took the pictures you had posted with the circled areas to him).  He used a 20 x lens to look it over, and we also took a couple of  pictures (one with his phone camera and one with mine set to high definition), which I’ve sent to you and Will separately, since they are too big to post.  Unfortunately, still no triangle date code...

I'm not sure, but I don't think so? David and watchmaker looked w/ a loop too. Here's some closer snippets.

Geoff,

Good eye!  There is actually something at the arrow, but its very, very faint.  That couldn't possibly be the triangle, could it?   And of course, yesterday we were mainly focusing on looking at the areas Stephen had circled in the other pictures...

Well heck, sorry you gotta open it up again, but that area does look like something might be there- maybe?   I think with loope and watch in hand, you may be able to tell.
