Mechanical watch time will drift over time because machining mechanical part has imperfection due to machine tolerance.

Traditional battery watches runs on internal quartz or crystal oscillator which is very accurate but over long period will also drift. The microseconds inaccuracy is diving clock pulse will accumulate over time. Battery factor will only comes to very end of battery life cycle because the circuitry can be designed to drive at constant current.

If accuracy is very important, then you need to go for watches that sync with cellular base station or GPS. Your phone use clock data from cell station which is synchronized to GPS satellite. Yes, due to distance from satellite to earth, the info delay 1s+ (no more than 2s if not mistaken), but the GPS receiver has auto-compensation to calibrate itself.  thumbsup.gif

Agree on the part of very accurate time keeping, mechanical watches will fade, but I don't see Rolex or Omega or Patek slowing down, in fact the demand to fine craftsmanship have surge as the people has growth in wealth. Not everyone need to have clock that tell to exact mili to nano seconds, in fact sometime I do wear watches that stop working, but the presence of having a mechanical watch on the wrist play the tricks on people's mind, especially the subconscious.

Lol I hardly wear the BLNR anyways. Maybe weekends, at most.

It's usually apple watch on the wrist for about 2~3 months.

Get a couple more of mechanical watch, then you will have different understanding in collecting watch. Accuracy is part of it but it will be less important as the journey progress... Only thing that is important is the $$$ in the pocket.  tongue.gif

Yea, I think I’m poison now and start saving for more premium watch zD

Rumours are saying that this year Apple Watch might be round shape and it looks nice tongue.gif

Thanks for the explanation. In fact someone also recommend me to get the Seiko GPS watch before which will automatically change time when we travel to another time zone.

Thanks for sharing, that link is super useful! rclxms.gif

But are you satisfied of your watch being slow constantly at 20seconds per 24 hours ?? hmm.gif

P/s to update, my watch just lost 0.5 seconds in 24 hours since yesterday! Wow! And I let it in the crown up position when I Went to bed. Will try another position tonight

Not satisfied but no choice, u need to pay higher price for higher end movement .

As u said, different position will affect the beat rate..

Guys, just to update, and i don't know why, suddenly the accuracy of my watch getting poorer and poorer.

it has now slowed by a total of 6 seconds/day as compared to my 2 seconds per day for the first week. The watch is now in its 2nd week of operation and the average accuracy im seeing is around 6 seconds lost per day sad.gif
