·Thank you all for your help, I’m really appreciate! I live in Canada and came visit my dad in Taiwan, so I figure I’ll get the watch repair here since it will be cheaper than in Canada.
One more question, for date adjustment, is it the same for all mechanical watch that, you can’t adjust date during 9pm to 3am range? Does it apply to all vintage Omega?
And what was the MSRP for a 1969 Omega Seamaster at the time?
Thank you @wagudc for the 168.024 story and history
Some newer ones have components designed to break if you force a quick date change in an off position
Some older ones have components that have sliding date changers that could absorb a mistake but if you get it caught, I've heard it jams and damages components
I'm not an authority but I'd say you shouldn't quick date change by pulling the crown around 9pm as at around 10pm the date change starts, and you shouldn't quick date change 1.5 hour after the date change to be safe, which is usually around 12pm - this is on a health watch
I advance the hour hand by 6-7 hours before changing the date to be safe, as it's a tiny effort
