This is a good quality movement, with endstones on the escape wheel, as many English duplexes were; they weren't a cheap thing to make, being very dependent on the accuracy of the escapement, and despite their technical inferiority to the detached levers and detents, were quite highly regarded in the first half of the 19th century. This one could well have been cased in gold, and it's unfortunate that its cap is missing.These aren't my area but looks to be better quality. Anyway, any info would be appreciated.
That's good, are there any marks inside the cap? I know John Matthews records all the cap marks he can find and tries to attribute them to makers.Regarding the dust cover, it is present and is signed the same as the mvt.
Do you mean that the balance wheel is compensated? That isn't unusual with these, I've even seen a freesprung example, which is much more unusual....and that it is equipped with a balance wheel.
As far as I can see, so does Greg's, and they're all screws, not nuts.Miguel´s watch has quarterscrews/-nuts on the balance wheel.
It may not be unusual, but it does point to the appreciation some watchmakers had for the duplex escapement.Hi Miguel,
Do you mean that the balance wheel is compensated? That isn't unusual with these, I've even seen a freesprung example, which is much more unusual.

Mine its a duplex escapement tooIt is it dated 1835 and has a compensated balance wheel, which is original, it is very unusual. It is credible because Dent was one of the very few makers who put compensated balances on levers before 1850.
Jon - I do not believe this is valid for London finished watches with duplex escapements.few makers who put compensated balances on levers before 1850
