Need a little help regarding working of automatic watches:

Sourab Supreme is my first automatic watch, on manual winding it runs for 40-45 hour without me wearing it for any time at all. But when I put it on wrist from a dead position, it runs for about as much time as wrist time - Yesterday I wore it for 10 hours and it ran for about 11 hours. Am I doing something wrong with how I should wear it? Does it need a combination of winding and wearing? Or the less running hours are due to less frequent wrist movements in wearing time? Hope the watch by itself is fine.

When picking up a dead watch, manually wind it fully and then wear it. Subsequently the watch will continue to self wind sufficiently so that 8 hours of use on a moving arm will allow it to tide over 16 hours of non use on your table. The key is to wear your watch daily, you will never need to handwind it, except maybe on friday evening to tide over till Sunday afternoon.

Excellent photo!
Jalal, your photographic skills are excellent ...like Sudip
Dear Mike and Vikrama thank you very much.
My photos are nothing in comparison with Fateh, Hari, Prashant Pandey, Sudip.....these gentlemen inspired everyone towards hmt with their good photographic skills.

Ultimately the rate of auto-winding will, as you suspect, depend how active you are. The movements in these watches self-wind somewhat less efficiently than those of, for example, Seiko, and so the advice about hand-winding seems sensible.

I am looking for some advise on my recently purchase of hmt watches. I have collected Janata, Rajat Supreme & NASS 09. Could you please help with the below questions?

1. When I change the time in Janata, I could do it only in the anti-clockwise direction. The clockwise movement unscrews the crown. Please note the winding stem is still intact, its just the crown seems to loose? What is the best way to tighten the winding crown?

2. In the Rajat Supreme, when I pull the crown, its seems to pull very easily and I couldn't stop easily for Day/Date adjust and I don't hear the usual 'click' sound. However, with the NASS 09, I could easily stop the crown for the Day/Date adjust or the Time adjust and I hear the 'click' sound very well.

3. The Day/Date change in automatic winding watches seems to be little hard and I have to turn tha crown a bit harder to move the day/date in both the NASS and Rajat. Please note I generally change the Day/Date when the Hour hand is at 6 o'clock position. Is it common in automatic watches?

4. I don't have a self-winding watch box and I hate to see Day/Date to be appearing incorrectly in my watches. How do you guys manage to keep the date/day correct on your self/auto winding watches.

Thanks in advance!!

Changing date is simple, but I think for 28-29-30-31 day months, you may need to adjust in such months seeing whether there are extra or lesser days. I have alos bought an automatic recently and not very experienced with its working, but this seems to be the way to me.

btw from where and when did you get Rajat.

Hi Ruminance - I bought the watches from hmt website on August. Please note when I say the date/day is hard, I am not complaining about the process, I feel like I am finding the day/date wheel mechanism to be a bit tighter as if the wheel got struck in-between while trying to advance the day/date.

The proper method to tighten the crown to the stem will require you to remove the stem and then do it. I suggest you live with it or take it to a competent watchmaker...

every watch is different, you will have to develop the knack to determine the first pull out stop
.
yes, day/date change operation is a bit torquey on newer 8205s installed on HMTs. Avoid adjusting the Day/date when the watch is showing between 1700 to 0600hrs.

If the watch is kept running, the day will advance correctly. the date will need advancing depending on the month. so if you don't have a watchwinder, just manually wind your watches everyday.
