The date on my Seamaster changed at 23:59:02

58 seconds before the stroke of midnight.

Is this considered accurate?

Can this change or will the date always change at that exact time on this watch?

What time does yours change?

The obligatory wrist shot.

Cheers.


O C D?

I just watched my green Seamaster again since I'm up and can't sleep and it changed right at midnight like the picture I took for the new year earlier this week.

For the semi-instantaneous date mechanism in the 8800 and similar calibers, the tolerance is +/- 10 minutes of midnight.

Cheers, Al
And if it's over tolerance? What does it mean then? Does it mean a watch that changes 8 min earlier is less accurate than a one changes on the dot?

Also, can it be cause due to playing with mechanism and changing dates in the 'bad zone'?

Who has a jbb where he/she needs to know the correct date between 11.50 pm and 0.10 am or else somebody will die if it's wrong?

Answer to your second question is no.

It means the hands were not installed properly in time with the date change.

Nope. The date change has nothing to do with the timekeeping of the movement. The date change is not even adjustable after the movement is completely assembled while the timing can be adjusted and regulated.

No.

A watch less accurate if the date change doesn’t happen precisely on the second when the time registers 12:00 midnight? You really have no idea, do you! Relieve yourself of your anguish, and buy a digital watch. Digital timekeepers are not watches, they are computers.

I think a lot of new mechanical watch owners have to manage their expectations.

This is tech from the 1600’s… breathe!

I'm usually asleep. When I wake up in the morning and look at my watch, the date's changed. Good enough for me.

Entertaining thread!

Mine are the same as above. When I go to bed, the date is accurate. When I get up, the date has correctly updated. My cheaper watches are equally accurate.

Next time I'm up at midnight, I'll try to remember to pay close attention for some more scientifically accurate data...
