I have a West End Secundus watch I was told between 1910 1930. Anyhow...the watch worked amazing when i got it. Literally kept time right to the second for over 2 weeks straight with regular winding. Now all of a sudden it stops while holding it in various positions and angles. I sent it for servicing and the guy said it was dry somewhat and he oiled it for me but other then that it looked in good condition on the inside. Its worked great for him...he took a video of it before he sent it back to me and showed me and rotated it in all positions and it worked excellent. I get in on my arm it stops. i hold it it stops..i set it down it runs. i pick it up it stops. I don't get it. Any help would be great as its very frustrating !!!
