Well, HMT is producing only one hand winded men's calibre as far as I now. It is a licensed Citizen, and is very robust and reliable as its ancestor. Good that in XXI century one can catch such a beauties on ebay any time !The movement in the Sona is common to most if not all hand wound HMT'S . I find them to be very robust and see lots of watches which have not been used for ages, spring to life with a simple cleaning/service.
Thanks for the tear down. The close up pictures are awesome.

That is a very generous offer of you - I've attached a photo of the part. You won't have the click spring by any chance as well - I got a bit negligent after the screw of the main spring winder broke ;-)If you could post a picture of the part you need, I can send it across... gratis.
I'll try that next time, thanks for the hintNice pics and story! Just a tip: if your camera has a manual white balance preset (most do), put it in the custom preset and snap a photo of a white piece of paper under the same lighting. It will adjust the white balance correctly so you don't get the yellow overcast. This is easy to do and removes the color cast from lighting.
Not to worry, I got a winding stem from an HMT Janata - that will probably fit.Ouuch!!!
After taking my new pilot watch apart to clean it (I found debris in it coming from the stem tube where there seemed to be some filler) I STUPIDLY managed to drop the movement about 30 cm onto my desk while the stem was fitted........ I was adjusting the hour hand to stop it touching the lume dots and it just slipped.
The stem hit the desk first and snapped off inside the watch.
I have removed the stub, but now have to track down a stem that will fit.
I should have left it alone.
Does anyone have a spare from a scrap watch?
GREAT!!!Not to worry, I got a winding stem from an HMT Janata - that will probably fit.
Shall I just ship it with the bumper when I do the hands?
How about starting now? An ideal candidate for your first foray into watch repair!My grandfather was an amateur watch-repairer, and I wish I had gotten into watches while he was still alive so I could fix my own stuff like you guys.
I recently got an HMT Jayanth (thanks Fateh!) that was working for 3 days until I tried to re-set the watch and pull the tiny crown. Long story short, my finger slipped and I think I pulled a little too rough, because now the dial moves when I turn the crown. And while the hands move, it feels like the crown loses traction at some point during a full rotation and spins freely for a few turns, before "grabbing on" again. The watch will run for about 20 seconds at a time before stopping. HMT is my first foray into mechanical watches so I don't know what's going on.
Trying to decide if this is worth servicing, since I have two sterling Janatas that work wonderfully and a Sona on the way.
It is likely that there is nothing much wrong, I think. Perhaps you have dislodged the stem slightly. Does it come right out, or is it still fixed inside the watch?Trying to decide if this is worth servicing, since I have two sterling Janatas that work wonderfully and a Sona on the way.
