Hi all how rare this hampden will be
its size 18 17J

Peter, when hitting us with these requests, we need to know the serial number. This could be anything from a "traveller's" watch to an early higher-end Hampden RR watch made when 18s and 17J were still RR Grades.

I should know better sorry here is the s/n 1338951

and here is the picture of the movement with out flag hallmark

You have a 3+ adjusted 1900 vintage Model 3, 17J RR Grade made with along with some "Deuber Watch Co. movements around its SN.

Given that it is marked adjusted, and that the Dual Hour Hand is original to the movement, if the case is a Decent Deuber Case, I would value it at $300-$400.00

Thanks David.

Dave I have few questions how do I know if this
double hour hand is original to the movement.
I been searching up and down on internet and few
book but can see any hampden watch with double hour hand can you point me to right direction or this is
you knowledge acguire from years of experience.
Or I just got my self Frankenstein pw put by some
"collector"

I don't think you have a franken-watch, you don't see a lot of dual time zone hands but I have seen them on most every brand. I would think it was not something that came from the factory but added by a jeweler per customer request.
