Hello i figure i add some of my watches even though they are already known models...after looking at the exact year for this watch i notice there isn't any lone eagles of this kind with a 21 10ae is this the wrong movement in this watch??...or do i have the model wrong? when i got this watch it wasn't running after and good clean and oil it keeps time up to a minute plus or minus a day after regulation...i was going to sell it but i don't know if some want to make a decent offer i will consider it...but i really like it even though its on  a womens band i have a wire lug band coming for something else but that project when south when the yoke flew somewhere in the room... here are the pics..Corrected Ambassador, i now remember that...thanks for the correction..

Here is a "Lone Eagle and an "Ambassador" side by side...There is a big difference in case size, crystal size, and no, engraving on the Ambassador, plus the lugs have no spring bar holes going all the way thru the lugs on either of them.

For now it is neither an Ambassador or Lone Eagle...1940 Unknown or maybe a 100% Bulova Frankenbully, IMO.

IMO it's a "Modified" Lone Eagle. Lugs cut off at the rings and re-drilled (not very well, but effective) to be able to take a larger band.

It would help if we had the EXACT MEASUREMENT OF THE CASE so it could be compared to a un-cut Lone Eagle.

You may have hit it on the head.  Definitely modified from original with the pin holes drilled out.

You guys are tough, The lugs ARE done well and arent cut bad are even and doesn't look bad... it would have been almost impossible to find a band plus those metal bands are uncomfortable anyway(although they make the art deco look, they aren't practical to wear every day...i have have seen this model before with this done to it.and this type of band..i didn't see any mark on the movement to see what year it was made unless the AAA helps..i am not sure...besides the 21 10AE is a better movement anyway..at some point  awhile ago(since the way the watch was when i got you could tell it wasn't touch in awhile) changed the either broken 10ax or simply wanted a better movement...the case measures 40cm by 26cm... one more thing on the lugs, it was done awhile ago most likely because spring bar holes use to go all the way to the end and on the outside of the lugs...i am sure if it was done recently somebody will used a drill stop, but that was the style back then....
             Another question is there any standard way watchmakers make service marks on the watch case? Does every watchmaker put the month date and year,their own way, however they feel like it...

To my knowledge every watchmaker has his own style for marking service/repair, but other watchmakers can read the code.

As to cutting the lugs off at the rings, any good jeweler/watchmaker could do this with ease. I've sat and watched things like that being done. With a little filing, clean-up and polish/buffing....WAH LAA....Takes a standard band and eliminates the metal fru-fru band (even though for display purposes I'll take the orig. fru-fru).

As to the movement swap, I'm pretty sure that doesn't surprise any member of this site. Happens on a daily basis, which makes our job a real pain in the A@*...

BTW, on your measurements, didn't you mean mm not cm???

Any member have this particular Lone Eagle that can supply measurements????

right mm or 4.0cm by 2.6cm... anyway i bet this stuff happened all the time...the watch came in alot of two and i only paid forty six dollars for this and another watch that was mint, so i am happy even if i chose to sell i am sure i will do good on this piece, its still very nice and Wearable...

Good observation Bob,

This type of lug repair (if that's the case) could also circumvent any damage done to the original lugs from use of an incorrect band or springbars.

The Watch could also be the 'ENGINEER' as there is no SS Caseback showing. - 1941 ad. or one We have yet to see in print.

a humdinger.

Thanks Mark, sometimes the simplest answers are the best. I don't believe this watch is a frankenbully, just something modified.

As a footnote, I used to use a jeweler (now deceased) who was truly a artist with dental tools  :-)

This type of modification could be accomplished very easy with the right tools and a steady hand.

i was thinking a drill press at first but then the out side of the lugs look as where the bit came out at not in...so i dont know what tool would be able to get between the lugs to do this, maybe you guys do...
