It’s been quite some time since I took apart this HMT Sona – as the barrel wheel screw broke off, I had to wait to get my hands on some spares, which have now materialized in the form of an old broken HMT Janata. Time to get the old plastic container out and to reassemble the watch …
I start off by cleaning the main spring, putting it back in and oiling it.
Bridges mounted, balance wheel happily turning …
Bottom plate ready for the dial.
Dial and hands mounted.
Movement goes into the case.
This is not too shabby – as the beat error is corrected at the collet, I’m not going to get crazy and try to correct a 1.1 ms. beat error on an HMT watch
A very nice looking watch indeed – especially considering the price.
If you consider value for money, this is a great bargain watch. The movement is well made, and the watch looks good.
One of my sons has an HMT Janata (the other one an Accurist), and this is a great watch as a first mechanical watch. If it gets lost or damaged, no huge harm done.
These go on eBay for around £20.
