10an with center sweep second possibly 1934?

JUST... got this watch this afternoon.  I suspected in the sale photos that it was unusual but boy howdy.

Hinged case, case serial# 441508, movement serial # 637253 15 jewel 10 an movement.

The case is 10k Rolled gold plate and the only Bulova indication on the case is just above the 10k marking.  Nothing but service marks on the interior of the case.

By the word unadjusted on the movement is what looks like a circle date mark.  1934.

Of course nothing even close in the ad section.

1934 maybe but I'd guess 1944. I've seen an ad in the data base for this watch but can'y remember what year. I'd start looking in 1944, then go back 10 years. Case style just dosen't work for 1934. IMO but could be.

I was figuring late 20s or early 30s because of the hinged case.  Those didn't seem to continue much past 34 or 45.

The Case style is '33 'TRIDENT' ..not certain who the manufacturer is.

Did the Trident come in non-engraved? The two examples on here are both engraved on the side verticles although I agree the case shape is similar.

Also the movement database lists the 10AN being produced from 1925 to 1937.

David, the movement data base is like the ad data base, not 100% accurate just yet. We have had to adjust some of the start/end years based on new movements discovered and watch/ad combinations.

I'm not seeing an engraved Bezel in the ad - Circle would Date it to 1934

ad Dated 1933. The Center Seconds is a humdinger...

With the description part about keeping time to the split second, that kind of covers the outer second track on mine as each second has 5 divisions in it, and each tick of the movement covers 1/5 of a second.

Oh, I forgot to mention that it is also keeping accurate time...;-}

Here is a different example which sports the same movement.  This one date codes to 1929.  The case is marked as Bulova.
