HMT Mechanical to Quartz

on Sat Apr 08 2017, 09:47
I was looking through my box of oddments yesterday and found this old Indian HMT mechanical watch that does not work . This then got me thinking would I be able to replace the mechanical movement for a quartz one .



From what I have read online the HMT ( Hindustan Machine Tools Limited ) was created using citizen movements they did create their own movements later on but these are still based on the Citizen movements.

This is the HMT 020 mechanical movement



It is a 17 jeweled movements and  is more or less equal to a common Citizen handwound movement, the Citizen Caliber 0201 . Having measured the movement I see it is 26mm in Dia.

I am hoping that with the movement being based on a citizen that hopefully and that is a big hopefully that a Miyota movement might fit the case and maybe the dial feel position may just line up .

more to follow once I remove the dial and hands and find where the dial feet position

Had a little time spare so decided to have a look at the position of the dial feet . Removed stem took out movement and guess what the watch was only ticking away happily.

I then thought it a shame to remove a working movement and replace with a quartz so back in goes the movement and stem and onto a strap it went



Looks at the watch on my wrist quite happy it was working until I noticed it had stopped so I decided to pull out the crown to wind it up ..... Oops



Back to my original plan now to definitely put a quartz movement in .. should be fun trying to remove the stem though to get the movement out

Panic over it suddenly dawned on me that most crowns screw onto the stem so very gently I pushed the crown into the tube and gently turned the crown and hey presto it gripped and tightened up onto the stem. All fully working again as a mechanical watch.

Do not panic I am currently looking on Ebay for an old Mechanical non runner as this is a project I really want to do . Would be a shame to use the HMT especially as it is working now

I've had a few watches where this has happened. It is possible to screw the crown back onto the stem but sometimes it can either unscrew again, if being turned anti clockwise, or worse just fall off and be lost as happened to me recently. Evil or Very Mad

I have been advised in the past to apply a small amount of glue on the stem to securely attach the crown. A good idea though by the time I could fiddle getting the crown back on the glue had dried. Rolling Eyes
