Omega SMP 300 power reserve time?

Gentlemen,

Bought my first ever Omega SMP 300 watch and I'm super excited about it. 😀 Also this is my first ever automatic watch. This could be most likely my lack of experience speaking but it bothers me. OK to my question, I know that the power reserve time specified by omega is of 48hours but mine doesn't seem to hold up that long. I don't wear this watch every day to work but in the weekends. I noticed that my watch get stopped after 10 hours or so once left in in the drawer without any movement. For an instance say that I wear it from on 1st of Jan from 10am to 2pm and place it safely in my drawer. Isn't the watch supposed to be stop working around 2pm on the 3rd of Jan at 2pm? Mine would just stop around 2nd of Jan perhaps at 1am in the morning or so. Mind you though I don't wind the watch much. Please can someone explain? Do you think that the watch is having some kind of a fault?

Also I'd like to know, given my usage is it advisable wind the watch once a day so that I don't have to set time every time I wear it during the weekends? Also how many winds should I do at a given time? I dont think crown will stop or give me any indication as to whether or not the watch is fully wounded. I read somewhere that the screw will be stiff and no longer can be wound when it is fully wound?

Really appreciate your inputs gentleman so that I can ease up my mind about this. Attached a pic of my beauty for ya 😀

I'll defer to the more knowledgeable members of the community, but my initial assumption you're haven't started with it fully wound which is why you're seeing a <48 hour power reserve.

On the master coaxial movements you can hear a subtle clicking sound once it's fully wound. I would imagine it's the same for the regular coaxial movement (?). Admittedly I haven't tried to 'fully' wind my non-MC watches.

If you really want the maximum reserve, then just manually wind the watch for say 30 turns before putting it away. You can't overwind a modern automatic, as they have a slipping clutch. Do this, and tells us how long you get before it stops. It should be in excess of 45 hours.

Thanks a lot for your inputs gentlemen, Really appreciate it.

Will certainly run that test and see where things are going. Can someone of you tell me how many turns I should do before I reach the point where the watch is fully wound? is it 30 or more? Although the modern automatics cannot be over wound is there a way for me to determine that the the watch has reached it's maximum number of winds. Perhaps a click or a locking sensation? Maximum I've done this is 30 winds and that's also once or twice but I never felt a difference.

Sorry for being a pain by asking lot of questions but I just need to confirm that, for the watch to be water resistant the crown has to be locked right? As in water can get in if the crown is at winding position ? I will wait for your inputs before I run the test gentlemen. Thank you very much.

You should hear a repeated click as the clutch slips in the mainspring barrel. But dear to stop after five mins of winding though!

Mine runs for about 48 hours after being fully wound.

When I wind mine, I give it about 40 winds or so from fully stopped. If you fully wind it you will hear a very quiet clicking sound as the clutch slips to prevent over winding. Screw the crown down before you wear it.

Hope you enjoy your new watch!!

Greetings gentlemen,

Apologies for not posting sooner. I did run the test and turns out my watch is bugs free, thank god. I full winded the watch at 11.10pm on the 15th of June (Australia local time) and safely placed inside the drawer. Guess what watch stopped on the 18th at 6.16AM. So it lasted whooping 55 hours 😀 when it was full wound. Oh I gave it about 60 turns before I assumed that the watch has reached max number of winds. Unfortunately I still cant figure out how to physically determine if the watch has fully wound cos didn't feel any difference(No slipping, clicking sounds etc). I just gave tit 60 turns and gave away.Nonetheless I'm relieved and that all that counts.

Gentlemen I'd like to confirm one more thing before I leave this thread. As you all know I wear this watch only in the weekends. Given that, is that alright to wind the watch just before I wear? or should I just wind once in 2 days or so, in order to keep the watch running always? In other words if the watch is kept powerless for long would it create mechanical problems and etc..?

Again thank you so much for all the good and valuable advice you've extended in order for me to get rid of a big headache guys. 😀 Awaiting your advice on my last question through. 😀
